Hi Forum People,
I have a very annoying downstairs Cold Radiator Problem
Our house is circa build 1999 and originally had an Ideal Classic boiler in a regular boiler conventional system. In September 2019, the boiler was replaced with an Intergas ECO RF 24 boiler configured as a conventional system and with a MagnaClean Professional 2 fitted in the upstairs airing cupboard.
There are 7 radiators upstairs ( 6 fitted with Drayton TRV4 and 1 fitted with Flomaster Manual )
There are 5 radiators downstairs ( 4 fitted with Drayton TRV4 and 1 fitted with Flomaster Manual ).
The downstairs toilet radiator fitted with the Flomaster Manual Valve is the offending one.
Recommendations carried out so far:
(1) All radiators bled.
(2) All radiators balanced with 1/4 turn and 1/2 turn lockshield process. TRV's set to 3 to 4 (6 is Max). Offending radiator is Flomaster manual so 3/4 opened until it reaches desired temperature. TRV valves tapped and none with pins stuck.
(3) When offending radiator returns to being totally cold overnight, never warms up again !
(4) Closed all other radiators and pushed hot water through offending radiator, heats up to desired temperature and is bled, little air is released. Works for a day or so then goes totally cold. Also the lockshield and TRV pipes are stone cold !
(5) Replaced radiator, but new radiator (Flomasta Type 22 600mm x 600mm 3499 BTU) still becomes cold after a day or so !
(6) MagnaClean seems to be doings it job as small amount of drained water is very clear.
Not sure what radiators are at the start and end of circuit ? Offending radiator could possibly be on the drop from upstairs ?
Intergas Boiler shows no problems, no errors and is serviced annually.
Any ideas on fix would be greatly appreciated.
