Hi I am confused! I have a Ferroli Optimax HE Plus 31C which feeds only 4 radiators 1 downstairs and 3 upstairs.
The first rad to heat up is the one downstairs at the same time the one in the bathroom heats up which is directly above the boiler in the kitchen, then very slowly by the 2nd rad in the middle bedroom and eventually by the 3rd in the front bedroom.
The further from the bathroom the colder the rad is and the 3rd rad is barely tepid. ? Sludge perhaps?
Now if I close the TRV to 0 in the bathroom then neither of the remaining rads get warm, why would that be?
Should I take each rad off and flush it outside?
Cheers
