Heat Pumps: To be or not to be?

Updated: Jun 7, 2023

With the current demand for heat pumps at an all-time high, it would behoove the end user to understand how they operate.


Traditionally, air conditioning condensers would run refrigerant through the structure via copper piping at the air handler and then simultaneously retain the heat and exhaust the cooling load. Then the refrigerant would carry the heat to the outside condenser and exhaust that heat into the air. With a heat pump, it works in both the summer AND winter. Operationally, heat pumps work in the reverse fashion where it exhausts cold air outside and draws the heat from outside compressor indoors. This kind of system comes with options:

  1. Heat pumps are operationally efficient to 40 degrees Fahrenheit outdoor temperature. To operate below that temperature, the air handler has to have electrical heat strips installed in order to compensate. If you have an existing heating system, you can operate a dual-fuel system in order maintain indoor temperature i.e., a boiler or furnace as a backup system.

  2. Bosch is the main brand we recommend not just because of operational efficiency but a front to back streamlined solution. It can work with the Nest thermostat or any other thermostat that can provide heat pump functionality.

  3. The idea of solar plays hand-in-hand with the idea of a heat pump based on electrical usage. As any installer worth their salt will tell you, you're biggest source of electrical consumption inside your home will be your compressor inside the heat pump. Since electricity is the fuel source, solar would play very well with that in mind.
