We have an oil burner that we run year round, for heat/water in winter and water only during the summer. Our water heater has been acting up and we got some parts replaced under waranty. Now the heating system is throwing a few expensive curve balls (a switch and valve both need to be replaced to keep heat from creeping up into the closest-to-the-furnace baseboards on the second floor and then again creeping down (albeit, less pronouncly) into the radiant pipes on the first floor. This creeping of heat occurs when there is no call for heat. Changing these items is expensive (we've already spent about $1K on new thermostats and other repairs this fall)-- but it strikes me that the only reason to undertake these newest repairs is to keep the heat from "coming on" during the summer. Aren't we better served just changing our water heater to electric and shutting down the furnace for half the year? Our electric bill is generally about $150/mo. in the winter and $250 in the summer. Oil is $2.50 gallon-- and , boy, does that loud oil burner make the first floor warm in the summertime. Anyway, anyone have some thoughts on this quandry. Many thanks. H.
