am guessing its not the job for my limited diy skills then
but thanks once again

hi thanks lunat, will have to tell him what you have advised....never know, i might be taken a little more seriously if i can suggest something technical.....

Hi
This leak will not have an effect on your gas bills.
The reason your bils are what they are is the controls setup.
Do you have a room stat?
Do you have TRV's?
Do you buy your gas from your landlord(through a secondary meter)?

When boiler is in central heating mode does the pressure rise quickly?

Hi linky, err...not sure what TRV's are... as for pressure increases in CH mode...sadly not....it just loses pressure all the time...have just manually topped up the pressure at valve underneath boiler, and within half an hour the pressure has dropped to virtually zero, and no we dont buy gas from landlord just piped in as normal

How long has this been going on (loss of pressure?)

 

[smurf182]

Hi, we have been having problems with the pressure since just before christmas, so roughly 6-7 weeks now

With that amount of water loss regularly you would easily spot a system leak unless you have wodden floors downstairs and the leak is under the floorboards. As you don't seem to have expansion vessel issues check if the pressure relief valve pipe is dripping....it should terminate outside.

If it is it needs changing

 

[linkyplumb]

TRV's = Thermostatic rad valves.
Have you checked all your system for leaks?

 

[smurf182]

now sorry if i sound a bit blonde here(im not honest), but would the outlet valve be on the outside wall where the boiler is situated(kitchen)?

 

[powell30]

Usually yes.......but not always. You'll know if it's leaking...drip. drip....

Check inside the boiler for any signs of a leakage. The water can be lost by leakage or evaporation. Check the CH and DHW diaphragms as the diaphragms have to be flexible to operate the electrical contacts and non porus to prevent fluid loss. Do not change components without good cause and proof.
