Air supply warmth pumps switch warmth, both from the surface air right into a constructing (heating) or from the constructing into the surface air (cooling). Their effectiveness in heating decreases because the out of doors temperature drops. At a sure low temperature, the warmth pump’s capability to extract warmth from the surface air turns into inadequate to fulfill the constructing’s heating calls for, necessitating supplemental heat.
Relying solely on the warmth pump in extraordinarily chilly climates might result in occupant discomfort and probably pressure the system, shortening its lifespan. The inclusion of a backup heating aspect ensures constant indoor temperatures are maintained, no matter exterior climate situations. This built-in method enhances the general reliability and consumer satisfaction related to warmth pump techniques.
