In HVAC applications, a calefaction pump is about a vapor-compression algidity accessory that includes a abandoning valve and optimized calefaction exchangers so that the administration of calefaction breeze may be reversed. The abandoning valve switches the administration of refrigerant through the aeon and accordingly the calefaction pump may bear either heating or cooling to a building. In the acknowledgment climates the absence ambience of the abandoning valve is heating. The absence ambience in warmer climates is cooling. Because the two calefaction exchangers, the condenser and evaporator, charge bandy functions, they are optimized to accomplish abundantly in both modes. As such, the ability of a capricious calefaction pump is about hardly beneath than two alone optimized machines.

In accouterments applications, a calefaction pump is sometimes acclimated to calefaction or preheat baptize for pond pools or calm baptize heaters.

In somewhat attenuate applications, both the calefaction abstraction and accession capabilities of a distinct calefaction pump can be useful, and about after-effects in actual able use of the ascribe energy. For example, back an air cooling charge can be akin to a baptize heating load, a distinct calefaction pump can serve two advantageous purposes. That is, a calefaction pump calm baptize boiler amid in the active breadth of a home could air-conditioned the home, abbreviation or eliminating the charge for added air conditioning. This accession would be best-suited to a altitude that is balmy or hot best of the year
