I have a 20x40 IG pool ...Detroit area weather. There is a 530 sf solar system installed on a roof which faces south east...not ideal, but works great when the sun cooperates.
Unfortunately, the sun doesn't always cooperate, and planning pool events is hard since I can't control the sun! I would like to augment the solar system with a gas heater. I ran a gas line...believe it is 1" and distance from meter is approx 120'. I have an all pentair system including easy touch with intellichlor and intelliflo .Also have a cleardeck in deck solar cover/reel
I by no means intend to swim in march...but it will be possible to gain a few weeks in may and June with a a gas heater
I believe the gas line I ran will limit the heater size...potentially to 200k (I'm going to confirm distance and size when it is not 3deg f outside and snow covered....) Maybe 250k...the distance charts are very cut and dry ( 0 to 100 feet 100 to 200 feet etc)...perhaps since I'm just a little over 100' I can go bigger. One of my fears is the gas line pressure will be too low and I will have a non functioning (but BIG), heater. I'm guessing a smaller heater will do well enough anyway for my low usage. Dies having my meter changed out make it possible to have a larger Heater on a given diameter line.
I am currently interested in the raypak/rheem digital and the Lochinvar energyrite.
The Lochinvar is more efficient, has a sealed burner and double the warranty on parts
The raypak seems well respected and is less costly.
I imagine either will do and will be low usage...so I am concerned more about long life and life cycle costs...I have to believe parts for the raypak are less.
Any comments appreciated.
Ps, I plan to enclose the equipment pad, approx 12x18' with an enclosure, so venting approx 10' will be necessary. Will either of these work better or be less costly to install taking venting into account? I may be able to place the heater close to a wall for easy/short side venting.
Thanks for your advice!
