Hi, Recently purchased a house that had been empty for a while with decayed heating system. I have the below system setup installed at present. The issue is there is no blending valve so I can’t have the boiler at more than 65 degrees. I want to separate the cylinder and rad feeds so I can run the boiler at 80 degrees for the rads and cylinder and get approx 55 degree water to the 3 UFH manifolds. I can see some potential issues just simply adding it to the primary flow rail etc. I have blank ports on the low loss header so I’m sure there is a decent solution. Maybe plumb the rads and cylinder to the boiler and then use the pump after the blending valve just for the UFH manifolds? many help appreciated.
