Effinity 93 Benefits
What This Means to the Building OwnerGrower
17% Fuel Savings Over Standard Power Vented & Separated Combustion Units
40% Fuel Savings Over Natural Draft Gravity Vented Units!!!
May Qualify for Local Rebate & Tax Incentive Programs
Separated Combustion Advantages– Reduced Air Changes & Heating Loads– Longer Lasting Heat Exchangers, Burners & Controls
PVC Vent Pipe & Power Exhauster Wheels– Lower Installed Costs & Replacement Costs vs. Metal
All Other Advantages of Gas-Fired Unit Heaters Apply– Warm Air Circulation, Vented Flue Products, Redundancy, Heat De-Stratification, Zone
Control, Low Installed Costs, etc.
Direct-Fired Efficiencies Without Direct-Fired Disadvantages– Water Vapor, Ethylene, Required Air Changes
Boiler Efficiencies Without Boiler System Disadvantages– High Up-Front Costs, Mechanical Rooms, Piping System Complexity, No Redundancy, Lower
Water Temperatures
