The Massachusetts Heating Cost Problem
Massachusetts has some of the highest electricity rates in the nation, making ground-source heat pumps — which use 3–5x less electricity than resistive heating — particularly attractive. Oil-heated homes in towns like Concord, Lexington, and the North Shore are prime candidates for conversion, with Mass Save rebates covering a significant portion of installed costs.

Massachusetts Geology & Drilling Conditions
Massachusetts bedrock is predominantly granite and gneiss, ideal for standing column wells. The stable 55°F groundwater temperature and favorable fracture patterns in the Merrimack Valley and MetroWest regions make open-loop geothermal systems highly efficient. Areas with deeper overburden (Cape Cod, southeastern MA) may require closed-loop configurations.
