Thanks for all the advice. I think its time I do some investigating myself based on what you all have said. I'll let you know what I find when I get her apart. Thanks again!

Purchased home last summer and have an older (approx 10 years) Teledyne Laars Lite 325K heater that developed a leak last year after not being used for several years while the house was for sale. Per my pool company its leaking from the heat exchanger itself, and the heads are good. I'm not really interested in replacing the exchanger due to cost, but had a crazy idea... Can I use radiator stop leak (or a similar product) to seal up the leaks? At this point, I'm going to have to buy a new heater anyways if it doesn't work so I don't really see what I have to lose. Figured I'd just dump it into the intake pipe, fill the heater will water and then discharge into a bucket and see if that stops the leak. Am I crazy here thinking this might actually work? Any insight would be greatly appreciated. Thanks.
