OUR GEOTHERMAL EXPERIENCE

At Chelsea we have over 32 years of top-notch experience in
geothermal design and installation. A geothermal system produces extemely high levels of efficient energy because a geothermal heat pump only uses electricity to move heat; not to produce it. A geothermal unit typically supplies four to five kilowatts of heat for every killawatt used. Three to four of these kilowatts of heat come directly from the earth itself, and are clean, free and reusable. For more go to our geothermal page.
