I have a Laars heater. It's going on it's 7th year of operation and I haven't had to replace a single component or have any repairs. I know that I am completely jinxing myself by posting this but I'd rather do some pro-active maintenance on it while everything is working to try to keep everything in working order for as long as possible.
My PB says it's a miracle that it has gone as long as it has without anything going wrong - "a real diamond in the rough"... If so, it's the only part of my entire pool that I haven't had issues with.
1. What is the typical life of a heater that is only used about 5 months out of the year?
2. Are there inexpensive components that can be or should be replaced proactively to extend the life of the heater?
