They extract heat from the ground during the winter and release heat back into the ground during the summer. Geothermal heat pumps are the most efficient type but also the most expensive to install.

2. Efficiency and Function of Heat Pumps

Heat pumps operate by transferring heat from one location to another rather than generating heat themselves.

They function similarly to a refrigerator but in reverse. Instead of removing heat from the interior, like a refrigerator does, a heat pump extracts heat from the external environment and transfers it inside your home using refrigerant.

The efficiency of a heat pump is measured by its coefficient of performance (COP), which is the ratio of heat output to energy input. A higher COP indicates greater efficiency.

Heat pumps can achieve COPs greater than 1, meaning they provide more heat energy than the electricity used to power them. It is important to note that heat pumps are most effective in regions with moderate climates.

In extremely cold climates, the heat pump’s ability to extract sufficient heat from the outdoor air diminishes. This is where EM heat comes into play, activating the heat strips in the heat pump to provide supplemental heat when needed.

In conclusion, EM heat, or emergency heat, serves as a backup heating source in air-source heat pumps. It is used when the primary heat pump encounters mechanical failure, freeze-up, or extreme cold weather.

By understanding the purpose and usage of EM heat, as well as how heat pumps work, homeowners can ensure their homes remain warm and comfortable throughout the winter season. So, embrace the warmth and stay cozy with the help of EM heat and your trusty heat pump!
