Four new hydronic furnace models are available. The design of the furnace works in conjunction with the company’s tankless water heating system to efficiently heat the entire home. According to the manufacturer, the hydronic furnaces produce comfortable, hydronic heat that is less dry than the heat from a typical gas furnace. To accomplish this, the unit uses hot water generated by the tankless water heating system to heat the air, which is then distributed throughout the home via the unit’s blower and the home’s existing ductwork. The hydronic furnaces feature electronically commutated motor (ECM) technology. The units accommodate standard cased evaporator coils. They offer a lower speed range that supports continuous fan operation, resulting in improved filtration and reduced temperature swings throughout the conditioned space. The microprocessor controller ensures maximum comfort by regulating the pump and fan sequence according to available hot-water flow and stopping operation to ensure that domestic hot-water needs are satisfied. The hydronic furnace knows to give priority to hot water during periods of heavy demand and will completely shut down the blower to prevent cold air from being spread throughout the home.
