ELCO Geothermal recently retrofitted a 10 year old Cape style home located in Hampden, ME. The home’s former heating system consisted of an oil fired New Yorker furnace with perimeter hot water baseboard fin tube radiation. The 2 acre lot has shallow ledge, so installing a new horizontal closed loop heat exchanger on the lot was not practical. The home has a 345′ domestic water well, rated for only 1 GPM of continuous water flow. The heating conversion budget would not allow for the cost a vertical closed loop heat exchanger (bore hole).
