Hello, my name is***** be patient whilst awaiting any responses as I'm not constantly available.Under the boiler there should be aa filling loop with two taps on it.. can you see it?
yes i can.
Can you also see the pressure dial
the pressure dial is on 0 now and the boiler is on
Is the boiler actually running then?
the boiler didn't fire and i boosted the pressure by turning the valve on the silver pipe of the tank and pressed the button of the boiler and it fired up. Now the pressure has dropped to 0
OK.. it must have been really empty, or, you may have a leak somewhere...Turn the tap again, but do it a little at a time... until it reaches 1.5 bar... Then bleed the radiators one by one, toping up the boiler as you go.. No higher than 1.5 bar though
When you have finished, turn both taps off
Please take a moment to rate my assistance.. Please use the smiley faces to do this.
Is the boiler rising and staying risen now?
the pressure has reached 1.5 bar but it is coming down as before
Have you bled the radiators?
yes. you mentioned two taps on the filling loop. i have turned the black one on the silver pipe horizontally. The other one i cannot turn
oK.. so long as one will turn.. it is safer to get both to close
the pressure has dropped to below the minimum
Then if you have bled the radiators correctly, you have a leak and need a heating engineer to attend to the system
is it safe to keep the heating on?
Do you know the model of the boiler
it just says vaillant. The block of flats is 14 years old
OK.. top up the boiler to 1.5 bar and wait to see if it drops again
i topped it up to 2 i am afraid
2 bar is ok... 1.5 bar is the ideal, but 2 bar is still safe
but the dial is coming down
it is just above 1
Is the boiler on an outside wall?
yes it is
Can you see a leak anywhere near the boiler?
is in the kitchen
Now can you go to the otehr side of the wall to see if the system is venting to the outside
it is dark and i could no see anything i am afraid
What is the pressure now?
it has dropped to 0 again
You have a very prominent leak then.. this could be anywhere that the pipes run... Turn off the central heating and the boiler and call a heating engineer as soon as possible
I hope you get it sorted without too much interruption to your holidays
