We need to replace our Hayward H250 pool heater and need some advice. Our neighbor is filling in his pool and has offered us his 10-year old 266K Raypak digital unit free of charge. It hasn't been used in 3 years and I will have to pay someone $500 to move it next door to our house to see if it'll work. It is very tempting as I am getting quotes of $3200 - $3500 for purchase and installation of a new unit. I also don't understand why the pool company quotes are so high. The pool stores sell the same heater for much less. Any advice is appreciated.
