i had a problem with the central heating, the one in the back bedroom and also in the kitchen and bathroom would not get very hot they are on 8mm pipework return and flow, the downstairs front room and the backroom are on 15mm return and flow
the flow pipe would always be hot but the return would only be luke warm i tried balancing the system with no luck
so i ripped out the floorboards in the back living room near the radiator, i noticed the 22mm flow and return pipes which were then connected to 15mm flow and return pipes and a gate valve connected to the 15mm return and flow pipes the gate valve was fully opened, the gate valve and the radiator is directly against the boiler which is in the kitchen so i closed the gate valve as soon as i had done this the kitchen, bathroom and back bedroom radiators were becoming much hotter
upstairs radiators are connected on 8mm but i believe they are also partially connected on 15mm under the floorboards
is it okay having the gate valve fully closed? because now all my radiators are just as equally hot, would this affect my CH system or boiler in anyway?
the only thing i have realised now is that i have noticed a hissing/humming sound coming from the radiators but if i open the lockshield valve fully then the noise slightly dissapears and radiators are still equally hot
please could you advise if the above is okay
