RE: Ecodan Pump Issues… Circulation pump turns off when heat pump compressor turns off  

By Patch321, 2 hours ago

  @ashp-bobba I agree. I think I'll simplify the system just or my own sanity. It's still oversized using the 30w/m2. I've got a garden office being built, might just run the pipes under the garden (ab...

RE: Ecodan Pump Issues… Circulation pump turns off when heat pump compressor turns off
