Geothermal is by far the best heating and cooling method on the planet. Cheapest to run, most efficient, quiet, best air quality, the list goes on and on. Geothermal, unlike solar, works almost anywhere. If you’re looking into renewables and securing your financial risks with energy costs. Geothermal is a great idea. Additionally, if you do have sun, geothermal and solar PV make a fantastic couple. Switching over to geothermal gets your heating and cooling needs provided by electricity and Solar PV can provide that power. Its a great one two punch for becoming a net zero home.
