For me, a solar cover provides enough added heat, but the wife tells a different story. My expected use would be mostly limited to weekends, turning it on Saturday morning to get a several degree lift for the weekend, and I suppose more swimming days in September. It is about 105 foot run from the meter to the pool, I got an estimate last year for $700 for the gas line and heater/plumbing install, but delayed for various reasons.
Based on researching these forums, Raypak is far and away the winner (though Amazon reviews tell a rather different story), so I am strongly leaning towards this one:
Raypak 009219 Digital Natural Gas 399,000 BTU Pool Heater
In terms of plumbing is there any configuration I should ask for from the installer in particular? Should I have it set up so I can bypass the heater if I'd like?
In the approximate location where I would like to have the heater, it would be somewhat under a tree where there is about 7 feet clearance from the ground. The heater looks to be 40 inches so that should give me enough for the required 3 foot clearance I see in the manual. Any concerns with this proximity?
For my use and pool size, any thoughts that this may not be the best choice for heat?
