X-Pump Block with an "on demand" water heater

edited April 29 in THE MAIN WALL
Has anyone ever had to add a pump to the on-board Taco 008 to overcome the high pressure drop of the "on-demand" HX?


Often wrong, never in doubt.

    It should be enough, but then there is always, it depends........

    I wrote a blog several years ago about this, take a look here

    We've used the X block numerous times with very positive results, never needed an additional pump. Its been a few years since we installed one but I'm pretty sure the specs were pretty clear with regard to head and gpm. What are you heating with the X block?
  • We're using Ecowarm panels to heat about 700 []. You can see them in the photo.

    This is the first time we've used Ecowarm. I like the product because it's plywood (3/4") and uses 1/2" PEX.

    Thanks for letting me know where that photo came from. It was in a library, I will tag it properly.

    Enjoy
