I have a pool just installed last year. I toyed with the idea of a heater but the cost was a bit too much with the pool and deck and decided to wait until this year.
I have a friend who built a house 7 years ago including an inground pool. He bought a heater ( at his wifes request) and installed it. He had it plumbed for the water lines but never attached the gas and therefore never even fired it up or turned it on.
Its a Hayward H300, 300,000 btu natural gas. I paid him 250.00 for it. I believe I got a great deal.
Got it home opened it up and cleaned it up (full of wasps nests ). Hopin to hook ot up this weekend.
Is there anything I should worry about buying a heater that has just sat there for 7 years ?
