no pressure and 2 radiators cool at top

[snadge]

ive been told i may have a small leak...

when we first moved in a few months ago the boiler reported 1bar pressure, now its zero... also the upstairs bathroom and small bedroom only heat up at the bottom

can anyone advise with this?

thanks

Top your system up to 1.5bar using the above filling loop, turn your heating on and check the blow off on the other side of the wall to which the boiler is situated.

It should be a piece of copper with 2 elbows on facing the wall.

Is there anything coming out from here?
