I've got an old Laars Telstar 50,000 BTU spa heater.
Just developed a leak in the heat exchanger. The leaks are real easy to see and they are not under much pressure. Just a couple of tiny sprays are shooting out.
The correct thing to do would be to buy a new heater ($650). The exchanger costs almost as much as a new heater ($500).
I'm thinking is such a small leak there might be an adhesive I could put on it to stop the leak. Anyone know of such a thing?
In case you don't know what a heat exchanger is:
Part number 47. Not sure what it's made of but I'm guessing bronze.
