Understanding Heat Pumps
When it comes to heating and cooling your home efficiently, heat pumps are a popular choice for many homeowners. Understanding how heat pumps work and the different types available can help you determine if they are the right option for your needs.
How Do Heat Pumps Work?
Heat pumps work by transferring heat from one area to another, rather than generating heat themselves. In cooler months, heat pumps extract heat from the outside air (even in cold climates) and transfer it into your home. During warmer months, the process is reversed, and heat pumps extract heat from inside your home and release it outside.
This heating and cooling process is made possible by the use of refrigerant, which circulates between the indoor and outdoor units of the heat pump. As the refrigerant absorbs or releases heat, it transitions between liquid and gas states, facilitating the transfer of thermal energy.
Heat pumps can provide both heating and cooling for your home, making them versatile and efficient year-round. To learn more about the benefits and considerations of heat pumps, check out our article on are heat pumps worth it in Canada.
