Evening,
Since having a new boiler, a Vaillant Eco 825 installed at the end of Feb I have occasionally had to top up the water due to low pressure (F22 error). I was doing this around once a month. Last week I did it twice and now this week I've had to do it every morning before being able to access hot water. Not good.
I have spoken with the company who fitted it who are coming round on Tuesday (I had to barter down from next Friday) to take a look at it but I have a feeling I know what they'll say. That being there's a problem somewhere in the system and the boiler isn't at fault. That may be the case but before they arrive I'd like to try and arm myself with as much info as possible and perhaps try and do some fault-finding myself.
I'd like to establish if possible where the pressure is being lost. This morning we had hot water. When getting in from work around 8 hours later there was none. The heating hadn't been switched on. I'm not sure if this counts as the heating being isolated from the boiler, I suspect not. If not then how can I do this and make this check? (I will no doubt have to go up into the loft tonight to refill it).
I can if necessary climb out and get access to the PRV pipe if that helps.
Finally, will the boiler need to be topped up with inhibitor due to the constant top-ups?
Many thanks for any help anyone can provide.
