Cold Climate Air Source Heat Pump

While most efficient heat pump models can function efficiently in temperatures as low as 27 degrees celsius it is a good idea to have a backup heating source for those unusually cold days where a heat pump loses its advantage in heating efficiency.

Cold climate air source heat pump.

As you can see the heating capacity of this air source heat pump drops off as the temperatures decrease. For many homeowners across the u s cold climate air source heat pumps ashps can be a cost effective option for improving home comfort while delivering energy and cost savings that make their homes more affordable to live in. Air source heat pumps are generally sized to produce enough heat for 80 90 of the annual heating load and should be able to satisfy 100 of your heating load when temperatures are above 0 c. Utilizing the industry leading evi enhanced vapor injection compressors with dc variable speed input our heat pumps are able to operate continuously in.

In the past air source heat pumps were more appropriate for warmer climates. It is intended as a model equipment specification to be used broadly by clean energy and energy efficiency program administrators in cold climates as a minimum requirement for program. The specification was designed to identify air source heat pumps that are best suited to heat efficiently in cold climates iecc climate zone 4 and higher. While the study described in this article focused on single zone systems multizone systems are expected to perform similarly.

Objective air source heat pumps ashps are a high efficiency technology with the potential to improve space heating and lower energy costs in homes located in cold climate regions where natural gas isn t available. Learn more about our air source heat pump research. Air source heat pumps gather heat from the ambient air while ground source or geothermal heat pumps extract it from the ground. Both system types are available with single and multizone indoor units.

Cold climate air source heat pumps are available as both central ducted systems and ductless systems. But in recent years the technology has improved so they re now viable for colder regions such as the upper parts.
