New Heater Recommendations

momlookingJuly 3, 2012

After a season without a pool heater, its time to replace our old one which is beyond repair. Our pool is roughly 25,000 gallon (18 x 36) vinyl - with a 3/4" gas line and a 3/4hp Hayward pump-- located in Northern NJ. We use it June through September. We have already sourced and are considering a Raypak 336A-EN-C Digital -336,000 BTU. Our town is insists on a licensed plumber and electrician for the install (as a home in the area burned to the ground from a pool heater). Because of these restrictions, our trusty pool company doesn't want to do the install and has offered to sell us the heater and let us arrange the installation. We have found a plumber and electrician to do the job.

Q? Are any of you unhappy with your Raypak? Do you love your Raypak? Do you have a similar (or exact) heater? Are there better heaters out there? If so what do you recommend instead (please no spammers) and why?

Suggestions and thoughts encouraged and will help us make this decision. Thanks!

While the gas connection for pool heaters is 3/4", more than a few feet of it will not provide enough gas. Typically, 1.25" or 1.5 inch pipe, depending on the distance from the meter is needed. A failure to do this will result in starving the heater, creating soot in the combustion chamber and accumulating on the heat exchanger, preventing any exhaust gasses from flowing out.

As for RayPak and Rheem, I gave up with them. They have some pretty significant issues with Mean Time Between Failure (MTBF), especially with heat exchangers, internal bypasses, less than idea chems, and rust.

I prefer Pentair Master Temp heaters. Even though they cost a little more, the MTBF is much longer. They don't have all the sizes I'd like to see in the HD models though. The HD models are needed with salt cells for the cupro-nickle heat exchanger they use. If you can provide at least 400 cubic feet of gas though, the 400K BTU model is as bullet proof a unit as I have seen.

In terms of how much gas is used, the overall amount is very nearly the same to get a job done with most sizes of pool heater. With the way water is heated, the higher BTU models just get the water warmed faster and keep it there.
