Whats a good temperature drop across a plate heat exchanger? im thinkin 15 - 20 degrees. ive got an OWB thats running hot, but the indoor boiler is firring every so often. im gonna go look at it again this weekend. I installed some boiler drains and back flushed the plates last weekend, but it didnt make much of a differance. the stoves been hooked up for two years and worked great till now. im open to any ideas.
Thanks. Dan
