Abstract: A clothes dryer may rely on a hybrid heat source for drying clothes. In some embodiments, the clothes dryer may rely on a combination of electrical energy to power the clothes dryer and hydronic heat to dry clothes. The hydronic heat may, for example, use hot water from an outdoor wood boiler circulated into a hydronic coil. Air passing over the hydronic coil may be warmed and delivered to the clothes dryer. The hybrid heat clothes dryer may reduce energy consumption from about 27 amperes to about 3 amperes.

Abstract: A dryer comprises a cabinet, drying drum and heat supply duct and refrigeration circuit. The refrigeration circuit includes a compressor, condenser, metering valve and an evaporator jacketed within an evaporator jacket containing a liquid. The heat supply duct houses the condenser and a resistive heat element. A blower passes air over the condenser and the resistive heat element and into the dryer drum. A temperature sensor is housed within the heat supply duct and positioned to measure the temperature of air entering the drum. The sensor is in communication with a control circuit. The control circuit switches the resistive heat element on and off in response to the sensing of air entering the dryer drum. In one embodiment the liquid jacketing the evaporator is sourced from a washing machine cold water supply line. In a second embodiment the liquid jacketing the evaporator is sourced from a geothermal heating system.
