Hi,
I've got an external Worcester Greenstar Heatslave combi, installed just over three years ago, regularly serviced, never given any trouble, though .there was a small leak recently due to a pipe/washer/nut coming loose. That was tightened up and the leak stopped.
I have two questions about the internal pressure gauge (ie the one under my kitchen sink that I never look at as often as I should).
(a) There are two black switches (probably the wrong name, but hopefully you'll know what I mean). These are to flick one way or the other so as to increase the pressure if it drops. The one on the left points directly up (ie towards the ceiling - or 12 o'clock). It's the one on the right that I'm not a hundred per cent sure about. Should it point towards the right? (Ie as if the big hand on a clock was pointing towards '3'.) I'm guessing so, as I made a note when the system was installed that if I wanted to alter the pressure, I turned the one on the right towards the left (which would effectively mean down, or the big hand pointing to '6' on a clock), then opened up the one on the left. (Or should the one on the right point down and my note should have read, turn to the right - or 'up'?)
For some reason, I thought the one on the right should point down, but then I couldn't turn it to the left, so I'm probably wrong. (And/or confused!)
The second question relates to fluctuating pressure.
(b) The gauge is set to 1.5 bar. I check it from time to time and it's generally OK. If not, I top it up. However, I'm fairly sure I've never checked it while the central heating is on. (The hot water is permanently on.) Is it normal for the pressure to rise quite a bit when the heating is on? I ask because I've just checked and see that it goes up to about 2.5 bar (and, on one occasion, even closer to 3, though not over).
I wasn't sure if there may be a problem with the boiler, or whether what I've seen is normal.
Hope I've made everything clear - and haven;t got all my rights and lefts the wrong way round.
Any help much appreciated - even if it's 'call a plumber'!
Thanks,
James
