Hello all. Our construction starts in just a few short weeks. We are constructing an 18x34, play bottom vinyl pool. 3.5' - 5.5' - 4- depths. Double end roman steps. Our builder uses pentair equipment. My husband asked our builder about electric pool heaters and pool pumps. We do not have gas on the property, our home is all electric. The pool builder discussed the heater with my husband and said he will order us a Pentair MasterTemp 400, electric. My concern is I have not found anywhere online that states the pentair master temps are electric. It appears to only come in gas and propane. Any experience? Am I misunderstanding?
