We are in the process of having a fiberglass pool installed in Western NY (Rochester area). I was very interested in a heat pump for efficiency, and for environmental friendliness. My dealer does heat pumps but says a gas pump extends the season 5 or 6 weeks, which is a good chunk of time for our short season. He mentioned I could check out the UltraTemp ETi Hybrid Heater, but I've seen some folks knocking it in these forums.
I had been looking at a Hawyard HP21254T or maybe even the 140 BTU version. If I use a cover out here, do I really need the gas heater as well to extend the season?
Open to specific equipment suggestions!
Thanks!
