1. A heating system comprising:
an evaporator having an evaporator inlet and an evaporator outlet;
a compressor having a compressor inlet in fluid communication with the evaporator outlet and a compressor outlet;
a water storage tank;
a first condenser proximate the water storage tank;
a first refrigerant circuit in fluid communication with the compressor outlet at a first end of the first refrigerant circuit and in fluid communication with the evaporator inlet at a second end of the first refrigerant circuit, the first refrigerant circuit configured to provide heat to heat the first condenser;
a second condenser for heating a fluid to provide a space heating effect;
a second refrigerant circuit in fluid communication with the compressor outlet at a first end of the second refrigerant circuit and in fluid communication with the evaporator inlet at a second end of the second refrigerant circuit, the second refrigerant circuit configured to provide heat to the second condenser;
a first enclosure containing the water storage tank, the first condenser, and at least a portion of the first refrigerant circuit;
a second enclosure containing the second condenser and at least a portion of the second refrigerant circuit in addition to the second condenser, wherein the second enclosure is disposed adjacent to and directly attached to the first enclosure; and
a single third enclosure containing the evaporator and the compressor, wherein the single third enclosure is disposed adjacent to and directly attached to the first enclosure.
