I live in a two storey duplex flat where the downstairs radiators are working well but only one of the three radiators upstairs are heating up. The one that works is in the corridor whilst other two are in the two bedrooms. I have checked that there is no air in the radiators and other things like the pin and these seem fine. Please could you assist?
Hi Arun it may have something to do with the pressure if your boiler I can get this sorted for you kind regards.scott
