Hi,
I managed to fit the new motorised valve for the central heating. After I fit it in, I tested by turning on the central heating and hot water at the same time (BAD IDEA !!!). The pressure valve (the red thing?) made lots of noise and the water and the radiator didnt become hot. So I bled the water heater and now the water heater is working perfectly.
Assuming I can just solve the problem using the same method, I bled one radiator upstairs (the furthest radiator from the boiler). The radiator didnt give any hissing sound and instead it was just splashing with cold water. So after googling around, i found out that it may require further bleeding process which then i did it by plugging off the pin on the radiator. After a few litters of water, the water came out warm. So then I plugged the pin on on the radiator and try to turn on the hot water from the controller. And the radiator is still stone cold. Funnily enough the other 2 radiators upstairs just need an air bleeding for a few second and it works perfectly. Meanwhile the radiators downstairs are all cold. I used the same method of bleeding a few litters of water and all of them are still cold. All cold radiators splashing cold water when i try to bleed them.
I googled more about this and ive tried and failed the following methods:
- turning off all radiators and let the problematic one on
- try to 'balance the system' by opening both valves on each radiator
- turn on water heater and then turn it off then turn on the central heating
- make sure the water supply in the small tank in the loft is full
I suppose this should be an easy fix but its been 3 days ive been trying to fix this problem and failed any suggestions please ? Thank you
