The Heat Exchanger works better, heats faster and much hotter than on electric circuit.
Hooked it up to my water heater and wood boiler and I shut off the heater breaker. The Heat Exchanger works better, heats faster and much hotter than on electric circuit. I use the wood boiler with the heat exchanger in winter (Nov-Feb) to heat the house and water and only use 10-12kwh per day of energy.

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.
