Aquatherm
When a First Co. Aquatherm® “Combo Heater” (air handler) is connected to an adequately sized natural gas, LP, or oil-fired water heater, the water heater becomes a dual function appliance that can provide comfortable, efficient space heating as well as hot water for domestic use.
Aquatherm
Aquatherm air handlers substantially reduce installations costs, heating costs, and increase the life of the water heater. Any water heater sized to accomplish both functions (space and water heating) will work…no special water heater is needed! Water heaters used for space heating will generally require extra gallon capacity and higher BTUH input. (See “Equipment Sizing”.)
