Londonderry, New Hampshire: Bosch Thermotechnology has announced launching its new Bosch Hydronic Air Handlers — a compact and advanced home heating system — which, when paired with the Bosch Greentherm Gas Condensing Tankless Water Heater, homeowners, the company claimed, can benefit from a more efficient heating system, with a virtually endless supply of domestic hot water.

The air handler, the announcement said, can replace furnaces with a ducted system, eliminating the need for a gas pipe, venting and fresh air intake required for furnaces.

The entire system, the company said, is easily managed by an integrated control board that connects to the home’s thermostat. When the thermostat calls for heat, the air handler immediately activates the integrated pump, turning on the fan 30 seconds later, allowing the heat exchanger to preheat to deliver comfortable warm air from the beginning, explained the company. After the thermostat is satisfied, the company said that the blower runs an additional 30 seconds to deliver conditioned air. The company added that the air handler has an integrated pump timer that turns on the water circulator for two minutes every six hours, to help prevent bacteria growth in the hot water system.

The company informed that the air handler may be configured to work with air conditioning systems, providing a complete heating, cooling and hot water solution. When the thermostat calls for cooling, the control board activates only the blower, it added.

The hydronic air handler, the company informed, connects seamlessly with tankless water heaters, transferring the unit’s hot water through a hydronic heating coil, which is circulated through a pipe and the warm air is sent through the residential duct system. The cool water in the hydronic coil then recirculates to the tankless unit to be reheated, it added.

Bosch Thermotechnology said that combining the two systems can simultaneously provide domestic heating and hot water to homeowners.
