S.W. Mn. | Have fuel oil forced air furnace now, considering geo thermal, Mn. weather, so questionis; what is the temperture one could expect from geo unit? I have encountered a variety of responses from geo. owners, ranging from no problem to, the heat is not real warm. Would keep the forced air duct work at this time, just looking for some experienced answers here. Thanks to all. | |
