Continuous operation of heat pumps during periods of low temperature is a normal occurrence. This sustained activity stems from the increased demand for heat within a building as the outdoor temperature drops. For example, a home set to 20C will require a greater energy input from the heating system when the external temperature is -5C compared to 5C.
Understanding this characteristic is crucial for homeowners. While seemingly counterintuitive, this constant cycling ensures a consistent indoor temperature despite challenging weather conditions. Historically, this operational feature has been a key factor in the growing popularity of heat pumps as a primary heating solution in diverse climates. This continuous operation allows heat pumps to provide reliable warmth, even in extremely cold temperatures, contributing to their increasing adoption as an energy-efficient alternative to traditional heating systems.
