The new Bosch Hydronic Air Handler can replace furnaces with a ducted system, eliminating the need for a gas pipe, venting, and fresh air in-take required for furnaces. The new air handler has an integrated control board that connects to the home’s thermostat. When the thermostat calls for heat, the air handler will turn on the integrated pump immediately and turn on the fan 30 seconds later to allow the heat exchanger to preheat. When the thermostat calls for cooling, the control board will only activate the blower.
The air handler connects seamlessly with tankless water heaters, transferring the highly efficient water heater’s hot water through a hydronic heating coil within the air handler. As the hot water circulates through the coil, warm air is sent through the residential duct system as the cool water by-product recirculates to the tankless unit to be reheated and reused.
The air handler is available in two models, AHU 50 and AHU 70, which can be sized with most CFM and BTU output ratings to suit a range of home sizes.
