How it works
The CompleteHeat® combination heating system consists of two modules,a heating module that produces heat andan air handling module that sends warmed air throughout your home. The modules can be installed together or separate to meet specific application requirements.The process begins when you shower, wash dishes, launder clothes or your house needs heating comfort. The internal thermostat senses the heat leaving the storage tank to satisfy these needs and triggers the combustion process to start.The heating module tells the combustion blower to draw in outside air, which is used for combustion. This means the system doesn't waste your home's conditioned air. After a short safety delay,a fuel/air mixture is sent into the burner where it's ignited by an electrical spark. The heated combustion productsmove through the stainless steel helical coil within the water storage tank, and the water in the tank is typically heated to 120° F (49° C) or your preferred temperature. After the combustion products have traveled down through the coil in the tank, condensation (water) is separated and drained, and the combustion products are vented safely out the top of the unit and on through the PVC piping to the outdoors. Hot water is directed to your faucets through plumbing at the top of the heating module. The same fuel that heats your water also heats your indoor air. When your home's thermostat senses a need for heat, a small water circulating pump draws hot water from the heating module and sends it through the space heating coil in the air handling module. The hot water in the coil warms the surrounding air. The blower turns on only after the coil has been heated andwarmed air is then sent throughout the air duct system into the rooms of your home.Water is continually recirculated back into the heating module to be reheated until your home reaches your desired comfort level.
