munchkin contender heat exchanger problems and thoughts.
I was wondering what your thoughts are on the contender boiler.
We have never installed any because of being concerned with the composite construction of the heat exchanger.
I have encountered a 3 of them installed by other contractors so far.
One was fine.
One I was called out to inspect and see why it was leaking and give recommendations to fix it....it was installed completely wrong, without going on forever it had no reducing valve and had 80psi water and blew the seal on the plastic header.
The third one was piped fine, pressure was fine, but the plastic header was cracked and was leaking.
I was shown the new NTI boiler that uses the same heat exchanger recently and am still concerned with it being plastic.
Any input would be great.
