So I've got an Ideal Elan 2 boiler (ancient) and apparently it's a pressure boiler.
Every now and again the hot water and central heating stop working, had heating engineers out via the landlord and apparently it's the pressure. I've got instructions but they don't really help!!!
"When the pressure drops below 0 turn the tap on the pipe and the knob under the gauge (done) and the pressure should move up. Once it's between 1.5 and 2 then turn the tap back and twist back the knob"
When I do the second bit it doesn't turn anything on, and sometimes even the pressure drops again. There's a knob ABOVE the gauge that changes the pressure too, does that change much???
Nothing seems to be working, no matter how much I fidddle with it! Any ideas?
