Comments about 350,000 BTU/Hr Low Pressure BPX Brazed Plate Heat Exchanger:

I have a in floor radiant heat system. It operated from an A//O Smith propane fired Vertex all house water heater,it does both domestic water and radiant heat all in one. I installed an outdoor wood stove that now heats my water. All of it, by using the heat exchanger I am not turning on the propane ever. I initially tried a side arm heat exchanger that just couldn't do the job.

  • 350,000 BTU/Hr Low Pressure BPX Brazed Plate Heat Exchanger


    Can this be used with potable hot water from a water heater such as the A.O. smith? I see that it has a heating application, but I assume potable water will be circulating through it from the water heater.

      Yes, this heat exchanger can be used with potable water on one side and fluid from the heating system on the other side.
