Hi all
All help is appreciated, I have vaillant ecotec pro boiler and 3 stories home, I have read on this forums about the efficiency of combi condensing boiler depends on the returns tempreature so I have tried the following with no help
D19 from 2 to 1, D1 to 8 minutes, back breaking time wasting balancing all radiators to 12 difference inflow and returns. Despite all of this I still have only 4 degrees difference on the boiler D40 is 56 and D41 is 52. The same difference even when the boiler temp was 75. Any ideas how to reduce the difference please I am pulling whatever left of my hair as after almost a month of reading and doing all of this I am still in same place
