Heat Exchanger Problem With Hayward Pool Heater

jtc1062

I have been through two heat exchangers on a New Hayward H100ID1 Pool Heater (Installed in June 2006) in less than 2yrs. The heat exchangers to me appear to be defective from the factory. The two I have been through lasted less than one season of use each. It took me forever to determine the original problem. I thought I just had a leak on one of my piping connections but it was actually the heat exchanger leaking. I had gas co. techs and a pool heater tech come out. Apparently the leak sprayed directly on the burner and would extinguish the flame and keep the gas from igniting as it should. As the heater would try to light, gas would build up in the casing until it finally found the spark and BOOM it would ignite. The service people kept trying to find spark or gas pres. problems when all along it was a defective heat exchanger. Hayward furnished me with a replacement heat exchanger which I installed in April of 2007. Yesterday I noticed water on the pad below my heater and the same problem has begun all over again. What I want to know is, has anyone had or run into a problem with hayward heat exchangers going out prematurely?

Look in the pump room does all the metal have corrosion on it? Water takes what it wants if it doesn't have it.

Yup, it's chemistry. Pool heater service is what I do, including warrenty work for Hayward. The leaks you're having are most likely caused by low alkalinity. That means acidic water. The worst I ever saw was three weeks, the gas wasn't never even hooked up.

Heres a very simple calculator for finding out chemical imbalance. There is more to the complex ones but for your example this should be fine. Notice how water temp. effects saturation index.
