Hi , I have just moved into a flat with an Ideal response 80 combi boiler.
it had zero pressure when I arrived so having read some literature I found in one of the kitchen drawers I opened up the taps on the silver braided pipe and pressurised to about 2 bar (probably too high I now know). started up the boiler and ran the hot kitchen tap, after a few seconds of cold I then had hot water flowing. turned the tap off and waited for the rads to warm up which they gradually did.
However the pressure kept rising, until at about 3 bar water started dripping down the back of the boiler and getting more and more strong.
turned it all off and looked at the paperwork again.
drained the CH outlet via the bleed valve until the pressure was zero and then refilled to 0.7 bar and tried again.
still pressure rose to about 2.7 bar when the drips started again .
turned it all off and resorted to the internet, found an installation PDF, all 73 pages.
this pointed to the expansion vessel which when I accessed the valved tube above the boiler emitted water when I pressed the schrader valve.
I guess this is not correct as the expansion vessel is not supposed to be full.
there is an 11 year old post here that suggests draining the system again and then pressurising the expansion tank to 1 bar.
how do I do that please? if I open the grey plastic valve on the CH outlet will that drain the expansion tank as well? if not how is that done? also to repressurise it do I just use a cycle pump and tyre pressure guage?
thanks in advance for your replies, I would have to move in on the coldest day of the year so far.
