Description
Single Wall Flue available in either 80mm (15-41kw) or 100mm dia (41-68kw) and for condensing models only, see page 12 for full accessory range.
Converting from a single wall to Twin Wall flue system in either 125mm (15-41kw) or 150mm dia (41-68kw) - suitable for condensing and non-condensing models, see page 12 for full accessory range.
Mistral has an established history spanning 10 years in designing, manufacturing and supplying the industry with reliable and extremely efficient EXTERNAL oil fired boilers.
Our unique inner Y section centrally located waterway design allows for excellent heat transfer to take place, particularly in the lower combustion chamber which greatly reduces the pressure build up normally associated with conventionally manufactured boiler types allowing for some of the highest efficiencies available today ( see inner back page ).
All outdoor models including the Std Utillity, Sealed System, Combi, Mega Combi and Combi Plus are supplied with a multi directional flue and terminal guard, and ( with exception to the Combi ) are supplied with a factory fitted Frost stat.
With the exception to our System boiler, which has four outputs ranging from 15-41kw (50-140,000) BTU all other Mistral Outdoor boilers are available in seven outputs ranging from 15-68kw70 40(50-230,000) BTU by far the widest number of outputs in the market today.
All models are self contained weather resistant units which are pre-treated, zinc phosphated for corrosion protection, then polyester coated in a durable green texture allowing them to blend naturally with their external surroundings.
All cabinets include multiple access points for pipe work and electrical connections and have a double lockable front access door.
Boilers can be purchased as either condensing or non condensing models (2 or 4 port).

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

The Mistral tdoor RangeThe Mistral Outdoor Range
Mistral has an established history spanning 10 years in designing,manufacturing and supplying the industry with reliable and extremeleyefficient EXTERNAL oil fired boilers.
Our unique inner Y section centrally located waterway design allowsfor excellent heat transfer to take place, particulary in the lower combustion chamber which greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types allowing for some of the highest efficiencies available today (see inner back page).
All outdoor models including the Std Utillity, Sealed System, Combi,Mega Combi and Combi Plus are supplied with a multi directional flueand terminal guard, and (with exception to the Combi) are suppliedwith a factory fitted Frost stat.
With the exception to our System boiler, which has four outputsranging from 15-41kw (50-140,000) BTU all other Mistral Outdoorboilers are available in seven outputs ranging from 15-68kw (50-230,000) BTU by far the widest number of outputs in the market today.
All models are self contained weather resistant units which are pre-treated, zinc phosphated for corrosion protection, then polyestercoated in a durable green texture allowing them to blend naturally with their external surroundings.
All cabinets include multiple access points for pipe work and electricalconnections and have a double lockable front access door.
Boilers can be purchased as either condensing or non condensingmodels (2 or 4 port).
- Front servicing- Free up space within the property- No oil entering the property- Easy outdoor access for servicing- Double locked front door- Std outdoor model has low level Multi Directional Flue outlets
(left, right or rear exit) see pg 8
Description
Single Wall Flue available in either 80mm (15-41kw) or 100mm dia (41-68kw) and for condensing models only, see page 12 for full accessory range.
Converting from a single wall to Twin Wall flue system in either 125mm (15-41kw) or 150mm dia (41-68kw) - suitable for condensing and non-condensing models, see page 12 for full accessory range.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

The Mistral tdoor RangeThe Mistral Outdoor Range
Mistral has an established history spanning 10 years in designing,manufacturing and supplying the industry with reliable and extremeleyefficient EXTERNAL oil fired boilers.
Our unique inner Y section centrally located waterway design allowsfor excellent heat transfer to take place, particulary in the lower combustion chamber which greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types allowing for some of the highest efficiencies available today (see inner back page).
All outdoor models including the Std Utillity, Sealed System, Combi,Mega Combi and Combi Plus are supplied with a multi directional flueand terminal guard, and (with exception to the Combi) are suppliedwith a factory fitted Frost stat.
With the exception to our System boiler, which has four outputsranging from 15-41kw (50-140,000) BTU all other Mistral Outdoorboilers are available in seven outputs ranging from 15-68kw (50-230,000) BTU by far the widest number of outputs in the market today.
All models are self contained weather resistant units which are pre-treated, zinc phosphated for corrosion protection, then polyestercoated in a durable green texture allowing them to blend naturally with their external surroundings.
All cabinets include multiple access points for pipe work and electricalconnections and have a double lockable front access door.
Boilers can be purchased as either condensing or non condensingmodels (2 or 4 port).
- Front servicing- Free up space within the property- No oil entering the property- Easy outdoor access for servicing- Double locked front door- Std outdoor model has low level Multi Directional Flue outlets
(left, right or rear exit) see pg 8
Description
Single Wall Flue available in either 80mm (15-41kw) or 100mm dia (41-68kw) and for condensing models only, see page 12 for full accessory range.
Converting from a single wall to Twin Wall flue system in either 125mm (15-41kw) or 150mm dia (41-68kw) - suitable for condensing and non-condensing models, see page 12 for full accessory range.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

SafetyPlease note that the products are extremely heavy, and great care should be taken when moving appliances around. Specialist equipment should be used where possible, and a full risk assessment, and plan of action should be undertaken, prior to purchase to avoid any injury.
Mistral manufacture a comprehensive range of Sedbuk A rated,high efficiency oil boilers for domestic and industrial heatingapplications. Culminating from years of boiler manufacturingexperience, ongoing research & development and our wealth oftechnical knowledge the specially developed Mistral ‘Y’ Section heatexchangers are fitted to all Mistral condensing and non condensingboilers providing much improved performance and operatingefficiency.
The unique ‘Y’ section centrally located waterway design allowsexcellent heat transfer to take place, particularly in the lowercombustion chamber. This greatly reduces the pressure build upnormally associated with conventionally manufactured boiler types.The ‘Y’ section design allows baffles to be a more open tolerance,providing for better overall running performance, smoother startups and cleaner combustion.
Baffles fitted to non central waterway heat exchangers, normallyhave to be extremely tight to attain required efficiencies, which cancause pressure build up and increased soot deposit in the boiler.The additional surface heat transfer area created within the boilerby the ‘Y’ section heat exchanger also allows Mistral tomanufacture high KW output boilers within typical domesticappliance size enclosures.
Mistral Boilers Limited are committed to offering the mosttechnically advanced and extensive range of domestic oil boilersavailable.

The Mistral Kwic Loc Balanced Flue System www.mistralboilers.com
The Mistral KWIC - LOC balanced flue systems have been developed to provide for both fixed and individual flue design options and, utilising the “0” ring seal and clip fixing system allows all parts to be quickly assembled.
All non condensing boilers need a boiler adapter to take up the space of the condensing unit.
The stainless steel LOW LEVEL BALANCED FLUE KIT is designed to make installation simple with a telescopic system and seals to allow for a perfect fit each time. The kit is compatible with all ( HX ) accessories and has a maximum extension of 575mm and a minimum of 355mm. Kits are supplied with burner air hose/clips, lubricant, boiler outputs between 15-41kw ( OD dia 120mm ) and with 41-70 for outputs between 41-70kw ( OD dia 150mm ),
We are now able to offer single wall flue systems in BOmm and 100mm diameters compatible with the Low Level Balanced Flue system. For more information please contact our sales staff.
The stainless steel HIGH LEVEL HORIZONTAL FLUE KIT is designed for simple installation with a vertical and horizontal adjustable extensions and seals which allows for on-site adjustment to suit individual conditions. The kit is compatible with all ( X ) accessories and can now create an offset system by using a 45deg elbow ( s ) and extension ( s ). Kits prefixed 15-41 are for boiler outputs between 15-41 kw ( OD dia 120mm ) and with 41-70 for outputs between 41-70kw ( OD dia 150mm ).
The stainless steel 3000mm VERTICAL FLUE KIT shares the same accessories ( X ) as the High Level kit and is designed for simple installation with seals to all accessories. By using our 45deg elbows, extensions and adjustable extensions it is possible to create offsets and therefore versatility from the system. The kit can be extended to a tested 6M and whilst traditionally ending with a Terminal Rain Cap as an alternative a Terminal Discharge Elbow can also be offered. Kits prefixed 15-41 are for boiler outputs between 15-41 kw ( OD dia 120mm ) and with 41-70 for outputs between 41-70kw ( 00 dia 150mm ).
Twin wall Plume elbow options are available which permit Low Level and Outdoor flues to be converted into vertical positions using ( X ) accessories.
NOTE - Local conditions, flue position and overall flue length can have an adverse effect on the boiler performance. The boiler may require further adjustment to suit the site conditions.
