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
