5 APPLICATION DATA

5.1 L.P.H.W. version

5.1.1 Water temperatureMaximum water temperature is 110°C.The minimum acceptable return water temperature is, for gas fired boilers 45°C and for oil fired boilers 40°C, at aflow rate corresponding to a ∆t of 20°C at nominal heat output.

5.1.2 Water pressureMaximum pressure 6 bar.The boiler is suitable for open and sealed systems up to a maximum pressure of 6 bar and a minimum pres-sure of 0.8 bar. The boiler is suitable for installation in basement or rooftop boiler houses.

5.1.3 Flow rateThe minimum flow rate through the boiler is obtained from the following formula:

nominal heat output (kW) = m3/h70

This minimum flow must be maintained for 5 minutes after the burner stops firing to avoid high temperature shut-down due to residual heat gain. Due to the design and manufacture of the boiler no specific minimum water flow requirement exists other than for over-temperature protection.

5.1.4 Water treatmentThe system should be filled with mains cold water (for the UK this will usually have a pH of between 7 and 8).Pressurised installations with a boiler/system content ratio of 1:10 or less should not require water treatment, provided that the following conditions apply:1. The system is flushed thoroughly to remove all fluxes

and debris and then filled completely once.2. Make up water is limited to 5 % per annum.3. The hardness of the water does not exceed 360 ppm

(20°D). All scale deposits will reduce the efficiency of the boiler and should be prevented. However provided the above is complied with any scale produced will not be too detrimental to the boiler efficiency and will not reduce the anticipated life expectancy of the boiler.

NOTE: Scale deposits in excess of 3 to 5 mm will reduce boiler efficiency and greatly increase the risk of premature casting failure.

As most systems contain a variety of metals which can react with each other to cause corrosion. It is con-sidered good practice to provide some form of water treatment (especially in open vented systems) in order to prevent or reduce the following:- Metallic corrosion;- Formation of scale and sludge;- Microbiological contamination;- Chemical changes in the untreated system water.

Suitable chemicals and their use should be discussed with a specialist water treatment company prior to car-rying out any work. The specification of the system and manufacturers recommendations must be taken into account, along with the age and condition of the system. New systems should be flushed thoroughly to remove all traces of flux, debris, grease and metal swarf generated during installation. Care to be taken with old systems to ensure any black metallic iron oxide sludge and other corrosive residues are removed, again by thoroughly flushing, ensuring that the system is drained completely from all low points.

NOTE: Please ensure that the new boiler plant is not in circuit when the flushing takes place, especially if cleansing chemicals are used to assist the process.

Under no circumstances is the boiler to be operated with cleaning chemicals in the system.

To summarise:- Minimise water loss;- Prevent pumping over in open vented systems;- Provide adequate air venting at all high points;- Keep pH level between 7 - 9 when using additives;- Maximum chlorine content of 200 mg/l;- Take advice on the suitability of inhibitors.

5.2 EconomisersECO’s can be delivered upon request (for natural gas only).

5.3 Flue gas dischargeFor the discharge of the flue gases, chimney draught is not required.Tests have shown that very good combustion results are obtained with zero draught at the boiler outlet.

Remeha P 200

5.4 Noise productionThe noise level taken at a distance of 1 m around the boiler is approximately 70 to 85 dBA. The noise level at the chimney outlet will, depending on load, type of burner and chimney situation, vary from 70 to 90 dBA, measured at a distance of 1 m from the outlet. If this noise production gives rise to problems in the imme-diate vicinity, then noise reducing or absorbing measu-res should be taken.9

5 APPLICATION DATA

5.1 Hot water version

5.1.1 Water temperatureMaximum water temperature is 110°C.The minimum acceptable return water temperature is, both for gas and oil fired boilers 40°C, at a flow rate cor-responding to a ∆T of 20°C at nominal heat output.

5.1.2 Water pressureMaximum pressure 6 bar. The boiler is suitable for open and sealed systems up to a maximum pressure of 6 bar and a minimum pressure of 0.8 bar. Installation of the boiler on rooftop or in basement is possible.

5.1.3 Flow rateThe minimum flow rate through the boiler is obtained from the following formula:

Nominal heat output (kW) = m3/h70

This minimum flow must be maintained for 5 minutes after the burner stops firing to avoid high temperature shut-down due to residuel heat gain. Due to the design and manufacture of the boiler no specicific minimum water flow requirement exists other than for over tempe-rature protection.

5.1.4 Water treatmentThe system should be filled with mains cold water (for the UK this will usually have a pH of between 7 and 8).Pressurised installations with a boiler/system content ratio of 1:10 or less should not require water treatment, provided that the following conditions apply:1. The system is flushed thoroughly to remove all fluxes

and debris and then filled completely once.2. Make up water is limited to 5% per annum.3. The hardness of the water does not exceed 360 ppm

(20°D). All scale deposits will reduce the efficiency of the boiler and should be prevented. However provided the above is complied with any scale produced will not be too det-rimental to the boiler efficiency and will not reduce the anticipated life expectancy of the boiler.

Note: Scale deposits in excess of 3 to 5 mm will reduce boiler efficiency and greatly increase the risk of prema-ture casting failure.

As most systems contain a variety of metals which can react with each other to cause corrosion. It is consid-ered good practice to provide some form of water treat-ment (especially in open vented systems) in order to prevent or reduce the following:- Metallic corrosion;- Formation of scale and sludge;- Microbiological contamination;- Chemical changes in the untreated system water.

Suitable chemicals and their use should be discussed with a specialist water treatment company prior to car-rying out any work. The specification of the system and manufacturers recommendations must be taken into account, along with the age and condition of the system. New systems should be flushed thoroughly to remove all traces of flux, debris, grease and metal swarf generated during installation. Care to be taken with old systems to ensure any black metallic iron oxide sludge and other corrosive residues are removed, again by thoroughly flushing, ensuring that the system is drained completely from all low points.

Note: Please ensure that the new boiler plant is not in circuit when the flushing takes place, especially if clean-ing chemicals are used to assist the process.



5.2 EconomisersECO's can be delivered upon request (for natural gas only). For specifications please refer to Technical infor-mation ECO 13/14/15.

5.3 Flue gas dischargeFor the discharge of the flue gases, chimney draught is not required.Tests have shown that very good combustion results are obtained with zero draught at the boiler outlet.

5.4 Noise productionThe noise level taken at a distance of 1 m around the boiler is approx. 70 to 90 dBA. The noise level at the chimney outlet will, depending on load, type of burner and chimney situation, vary from 70 to 90 dBA, taken at a distance of 1 m from the outlet. If this noise production gives rise to problems in the immediate vicinity, then noise reducing or absorbing measures should be taken.

5 APPLICATION DATA

5.1 L.P.H.W. version

5.1.1 Water temperatureMaximum water temperature is 110°C.The minimum acceptable return water temperature is, both for gas and oil fi red boilers 40°C, at a fl ow rate corresponding to a ∆t of 20°C at nominal heat output.

5.1.2 Water pressureMaximum pressure 6 bar.The boiler is suitable for open and sealed systems up to a maximum pressure of 6 bar and a minimum pres-sure of 0.8 bar. The boiler is suitable for installation in basement or rooftop boiler houses.

5.1.3 Flow rateThe minimum fl ow rate through the boiler is obtained from the following formula:

Nominal heat output (kW) = m3/h70

This minimum fl ow must be maintained for 5 minutes after the burner stops fi ring to avoid high temperature shutdown due to residual heat gain. Due to the design and manufacture of the boiler no specifi c minimum water fl ow requirement exists other than for over-temperature protection.

5.1.4 Water treatmentThe system should be fi lled with mains cold water (for the UK this will usually have a pH of between 7 and 8).Pressurised installations with a boiler/system content ratio of 1:10 or less should not require water treatment, provided that the following conditions apply:1. The system is fl ushed thoroughly to remove all fl uxes

and debris and then fi lled completely once.2. Make up water is limited to 5 % per annum.3. The hardness of the water does not exceed 360 ppm

(20°D). All scale deposits will reduce the effi ciency of the boiler and should be prevented. However provided the above is complied with any scale produced will not be too detrimental to the boiler effi ciency and will not reduce the anticipated life expectancy of the boiler.

NOTE: Scale deposits in excess of 3 to 5 mm will reduce boiler effi ciency and greatly increase the risk of premature casting failure.

As most systems contain a variety of metals which can react with each other to cause corrosion. It is consid-ered good practice to provide some form of water treat-ment (especially in open vented systems) in order to prevent or reduce the following:- Metallic corrosion;- Formation of scale and sludge;- Microbiological contamination;- Chemical changes in the untreated system water.

Suitable chemicals and their use should be discussed with a specialist water treatment company prior to car-rying out any work. The specifi cation of the system and manufacturers recommendations must be taken into account, along with the age and condition of the system. New systems should be fl ushed thoroughly to remove all traces of fl ux, debris, grease and metal swarf generated during installation. Care to be taken with old systems to ensure any black metallic iron oxide sludge and other corrosive residues are removed, again by thoroughly fl ushing, ensuring that the system is drained completely from all low points.

NOTE: Please ensure that the new boiler plant is not in circuit when the fl ushing takes place, especially if cleansing chemicals are used to assist the process.



5.2 EconomisersECO’s can be delivered upon request (for natural gas only). For specifi cations please refer to Technical infor-mation ECO 13/14/15.

5.3 Flue gas dischargeFor the discharge of the fl ue gases, chimney draught is not required.Tests have shown that very good combustion results are obtained with zero draught at the boiler outlet.

5.4 Noise productionThe noise level taken at a distance of 1 m around the boiler is approximately 75 to 90 dBA. The noise level at the chimney outlet will, depending on load, type of burner and chimney situation, vary from 75 to 90 dBA, measured at a distance of 1 m from the outlet. If this noise production gives rise to problems in the imme-diate vicinity, then noise reducing or absorbing measu-res should be taken.
