    Pool heaters

    Can anyone help me decide which pool heater to get & how many btu's should I get?
    My pool is about 35,000 gallons with about a 720' surface area. I am replacing a 25,000BTU Hayward which looks to be 20 years old (we just bought the house.) Are haywards still that reliable or should I be looking at a different manufacture?

    Re: Pool heaters

    did you mean 250,0000 btu?

    Hayward is notoriously unreliable (especially the newer models) Lots of talk about that if you search the forum.

    Raypak seems to be the most reliable.

    The Raypak R406A looks like a good option if you have natural gas.

    Raypak definitely seems to be the favorite on these forums, I just got the 406A last July and love it. With a pool that size you want to get the highest BTUs possible, mine heats my 21,000 gallon pool about 2 degrees per hour.

    We have a couple of pool pros (in the industry, or ITI) on this site and they all seem to recommend Raypack as the hands down winner (simplicity of design, maintenance is easier and less costly, units are highly reliable and well-built).

    For your size pool I think you'll need a 400kBTU/Hr unit. HOWEVER, check your gas line and meter setup. If you're upgrading by that many BTUs, the gas company will likely need to install a bigger meter to provide sufficient supply.

    Oops. Yes, I did mean 250,000. Thanks for the help. 1st time owning an in ground pool. I was looking around online & all heaters seemed to have mixed reviews. I was leaning towards the Haward just because the one I'm replacing seemed to last a long time. I will look at the Raypak now.

    Welcome to TFP,

    No doubt you'll need the 400 series with that size of pool and no less. Raypak, and Rheem are one in the same too just FYI.

    Re: Pool heaters

    Going with a Raypak heater. Now the only question I have is, should I order a Millivolt or a digital heater? What are the pros & cons of each?

    Re: Pool heaters

    This as an older thread I just saw which may still apply. I am about to replace a millivolt Hayward heater which was just a constant PIA. Every time it started without fussing of some kind I was thrilled. It runs off of the energy of the pilot light (wasting gas all day), and there is so little power off the bat that any issue with any part and it just does nothing. Total PIA.

    Re: Pool heaters

    35,000 gallons and you had a 250,000 BTU heater? How did that work out? Does not seem like its enough BTU's.

    I just bought a 206,000 BTU Raypak. My pool is 20,000 gallons though, and even that I was told was not enough from the pool store????

    Re: Pool heaters

    I have a 206A and it suits me just fine. (20*40 approx. approx. 30K gls) Now if you're trying to keep it toasty in early March or late October you could have some trouble.
