What Is a Ground-Source Heat Pump?

Geothermal systems are pretty ingenious. Harnessing the steady temperature of the Earth just below the frost line, these systems can heat and cool your home without the use of fossil fuels. One of the key components in the system that allows it to work as it does is the ground-source heat pump. Heat pump technology can be used in several ways, including air-source and water-source, making them very versatile devices. However, it takes expertise to work with a heat pump. If you are planning to use a heat pump for this winter’s heating, make sure you hire experts you can count on: Sound Heating.

How Does a Ground-Source Heat Pump Work?

Heat pumps work by transferring heat from one location to another. With a ground-source heat pump, the heat pump is installed in your home, typically in a basement space if you have one, and is attached directly to the ground loop of your geothermal system. The ground loop has an anti-freeze solution in it that absorbs the stored heat in the ground. This heat is transferred to the heat pump, where it is concentrated in the heat exchanger. Once the heat has been compressed, it is distributed into your living spaces.

In the summer, the opposite happens. The heat pump absorbs the hot air in your home and transfers it to the ground loop, where the surrounding dirt acts as a heat sink and absorbs the heat.

What Are the Benefits of a Ground-Source Heat Pump?

  • Very energy efficient – heat pumps use a small amount of electricity to operate and no fossil fuels at all.
  • Comfortable heating and cooling – heat pumps distribute heating and cooling in a low-volume way, so both heating and cooling are gradual and, for many, more comfortable.
  • Long lifespan – the life of an average heat pump is 20-25 years, as compared with that of a furnace or boiler, which is 15-20 years.

If you are looking for improved efficiency without sacrificing comfort, a ground-source heat pump may be just the heating system you need. Call Sound Heating today and schedule heating service in Tacoma with one of our installation experts.
