Abstract
Compressed refrigerant from a heat pump compressor flows through a first of three heat exchanger passages that are in mutual heat transfer relationship. Radiator water from a reservoir flows through a second of those passages and back to the reservoir in a heat exchange circuit. A radiator circuit that has at least one radiator is connected with the reservoir in parallel with the heat exchange circuit. Through the third passage a source of unheated tap water is communicated with a tap system from which heated tap water can be drawn, flow through that third passage being counter to refrigerant flow in the first passage. In the heat exchange circuit radiator water can be pumped through the second passage counter to refrigerant flow to be heated or counter to tap water flow for tap water heating. A separate pump in the radiator circuit circulates radiator water through it as needed to meet heat demands at the radiator. For supplemental heating another heat source can operate in a third radiator water circuit that is connected with the reservoir in parallel with the heat exchange circuit and the radiator circuit.
