So far so good. 30 plate version.
Purchased to replace a 20 plate exchanger. Quality appears to be good and install was easy. Did need to use Teflon tape on top of thread dope to address small leak with only the thread dope. Only in place about a month but so far working excellent in my hot water from outdoor boiler application.

Unlimited Hot water.
I purchased two of these. Arrived quick. Install wasn’t bad. I went from a side arm heat exchanger to these. I would run out of hot water with the side heat exchangers. With these I have unlimited hot water. I highly recommend these heat exchangers.
