    Jandy Legacy LRZ Heater Died :(

    Hi everyone, our pool heater just started leaking profusely, and I'm looking for a little help. I'm stumped because the heater was brand new, installed in 2012 by the previous owners of the house, (we moved in this past November after the pool was winterized) by the local pool company. It has been working all season, although about a month ago the pilot stopped staying lit so we had that repaired.

    According to the HVAC person, the cause of the leak is a very cracked heat exchanger (this is also what came up when I was researching probable causes of the leak). They are suggesting to replace the unit, as the cost of the repair would be almost as much as the unit. Unfortunately the old owners didn't buy the heater from the pool company who installed it, so there is no warranty from them, but we're going to check with Jandy if there's anything there. The pool company have suggested that it could be poor water chemistry that caused the issue, BUT we opened ourselves and haven't used them at all since we moved in, so I'm wondering if they're just trying to scare me into becoming a customer!

    The water chemistry has been fine all season, based on everything I've read/seen/my tests, though who knows what it was like last year. The HVAC guy thinks it's more likely that it wasn't winterized properly, and that it has maybe been cracked since winter but just now it got worse and finally blew. I'm inclined to agree with that since a) I know the old owners didn't do other things properly around the property, including not draining the garden hose hookup outside, so that burst over the winter, and b) They didn't do other parts of the winterizing for the heater that were noted in the heater manual when I opened in the spring.

    Anyway, I guess I'm just wondering if there's any way this is my fault, since I'm a first-time pool owner, and would hate to think I broke something. My test results, taken the same day the leak was discovered were as follows:

    pH: 7.5
    FC: 6 - - this is a bit high because the pool had been covered for a week and it's been really cold, didn't turn down the SWG % enough I guess.
    CC: <0.5
    CH: 125
    CYA: 30-40 - - at one point earlier this summer I was getting levels of 50, haven't added more since it's barely been sunny
    TA: 100
    Salt: 1870 -- we have the "low salt" model of aquarite, so this is a bit high and has been higher (added too much salt at the start of the season) but it was never high enough to make the SWG unit turn off, and was always well within the parameters for a normal SWG, so I can't see how that could have damaged the heater.
    It's a vinyl pool, if that helps.

    I'm just really annoyed, this is an expense we weren't expecting until at least a few years from now, wondering if it's even worth replacing it at this point. Thanks for any insight you can provide.
    Vinyl in-ground pool, around 24,570 gallons (93,000 litres), with SWG, sand filter, gigantic Jandy Legacy heater, Hayward SuperPump. Anything more please ask, new to all this!

    If it was purchased in 2012 it "could" still be under warranty. However, heat exchangers leak for one of two reasons. Lack of draining (for folks in colder climates) and poor water chemistry and more than likely Jandy, they are the warranty holders, won't cover it. Seeing that you are the second owner there is no telling what caused this.

    It's not worth fixing as the cost will be pretty close to a new unit. Purchasing a new unit then gives you a full warranty plus you can be assured that it's taken care of properly.

    Thanks, that's about what we've been told by everyone else, too. Now we've been quoted something like $3300 to replace it so I think we'll be shopping around a bit.

    I would consider a different brand as well. If you do some searching here you will find some good info on heater options.

    I can pick up a Hayward h150 on kijiji for 950, there's another different one for even less. I'll have to research them more but is there anything in particular you could recommend I look for or stay away from? I thought the jandy worked fine, when it worked that is.

    Looks like you just have a pool so if you want to heat it properly, a 150 is going to take a long time. You would be better served with at least a 250K BTU or better a 400K BTU. I wouldn't buy something used or you could very well end up with another heater like you have now.

    Thanks, I was wondering if that one might be too small. There's an old laarslite for 400 but I'm hesitant to spend the money installing something that might break down. We might just have to go new. Boo.
