Hi all
We have been having issues with our central heating/hot water for a few weeks now. It loses pressure really quickly (1 bar in a few hours). It loses this pressure even when the central heating and hot water are not on.
We have had Worcester Bosch out today to look at the boiler as it is still under warranty - they isolated the boiler from the pipes which confirmed that the issue is in our pipework, not the boiler.
All pipework is in studwalls/ceilings, except for two radiators on the ground floor (one under a floorboard/carpet floor, one under a concrete/tiled floor).
There are no obvious leaks anywhere in the house - as I mentioned, this has been an issue for a couple of weeks, so I think we'd have noticed if the leak was anywhere else.
I have had a bag over the pressure release valve for a week now and this is not leaking.
My questions are:
(1) Can we re-pipe these two ground floor radiators from the boiler rather than digging up the floors?
(2) Is there something else which could be going wrong here - maybe the expansion vessel? If we are losing so much water from the system, would the expansion vessel be leaking?
(3) Is our only option to go under the floor in each room?
Thank you in advance for your help.
