space requirements for geothermal heat pump systems
My husband and I are interested in geothermal heat pumps for our home in Boston, but I'm not sure that this is an option given that we live near the end of a very narrow dead end street in Boston. What kind of machines are needed to dig the trenches and how big are they? I'm not even sure that they could be brought to our backyard--or even if our small backyard is large enough to accommodate the piping. Would someone be able to give me a basic idea of how these systems are installed? Many thanks!
