I'm considering pellet fuel but I have a couple of questions...First some background, My house is about 4,300 SF, currently heated via an oil burner, hydronic raditors. Have 2 fireplaces. Would it make sense to replace 1 or both fire places with inserts that use pellets or add a pellet boiler? If I went with a pellet boiler can it be outside, or is it better inside? Any local regs? Long Island NY. Can I use a PB for swimming pool heating? Think that'll do it for questions, until I get answers and then have more questions Thanks in advance!
