I am considering buying a pool heater for my pool. My pool is 15 by 30 inground and about 14,000 gal. I live in Buffalo NY and have a short swimming season. I looked into solar heaters but my roof space is about 15 by 18 feet where I could put the panels and I am not sure how to install them. A pool company quoted me at about $2,000.00 for a gas heater installed with gas line installed. Any suggestions on type of heater - gas or solar? If so what kind. Any advice would be greatly appreciated.
