What are Heat Pumps and why talk about them in summer?

Updated: Dec 30, 2020

A Heat Pump is a heating and cooling system that operates in a more efficient, cost saving way. The same heat pump can both heat and cool by extracting heat energy from the surrounding environment and transferring it from one place to another. During the dog days of summer your heat pump seamlessly transforms to air conditioning - a real cool pump. And when the temperatures drop, just switch back to heat mode. Modern cold-climate heat pumps are now better suited for Orange County, operating even in subzero temperatures. Heat pumps eliminate on-site combustion and fuel storage, making them a cleaner, healthier, and quieter choice.

There are two primary types of efficient heat pumps: Air Source and Geothermal. If you heat with oil, propane, or electric resistance heat, you could save hundreds of dollars a year on your heating bill by switching to one of these two heat pumps. They're the future of comfort.

Air Source Heat Pumps

Air source heat pumps (ASHP)— often known as “mini-splits”— are electric appliances tha tprovide heating and cooling by moving heat into a building (for heating) or out of a building (for cooling).

​Today’s cold climate air source heat pumps can extract energy/heat from the air all the way down to -13°F. In the summer, the process is reversed, and heat is absorbed from the cooler indoor air and moved to the warmer outdoor air. With both ductless and centrally-ducted models, their versatility makes them a popular choice.

Geothermal Heat Pumps

Instead of the outdoor air, Ground Source (or geothermal) heat pumps use the ground as a

source of energy/heat.​ The earth beneath your property remains a reliable 50-60 degrees year round, and these systems only use enough energy to close the gap to a comfortable indoor temperature.

Geothermal heat pumps accomplish this by running a water mixture through piping (“ground loop”) buried in the ground and using an indoor heat pump unit to extract heat from this mixture. The indoor heat pump unit will then circulate this heat through your building like a traditional heating system. In the summer, this process is reversed and heat from your home is transferred into the ground. Cool, indeed!

Both Air Source and Geothermal Heat Pumps can help you save on your energy bill and improve the comfort of your home, all while reducing your greenhouse gas emissions.
