Mines is in the attic too 1.5 is good. There should be a filling loop. With it being in the attic I have to top up every 3 to 6 months. Just with it having to travel so far. But TJ will beable to confirm. Mine was fitted last January and toppex it up twice.
That isnt right....Quote:

A nice new one shouldnt need touching for atleast a year at a time.
The things I've changed on mine to slowly get it back to health:
Expansion vessel - replacement for it = £150 + time to tear the whole thing apart... OR fitted £20 external expansiono kit and plumbed it to the original locaion :D
Divertor valve service kit
divertor valve actuator
IT does need a new pump, new heat exchanger and new pressure relief valve as once those go off they leak.
Jack you'd probably want a new PRV as a matter of course and then keep an eye on things
My 'new' (probably 6 years old lol) combi boiler needs a slight pressure top up every 12-18months. And by slight I mean 0.1-0.2.
Doesn't sound right to need to top it up every 3-6 months.
It's a Worcester, they have a handy troubleshooting thing on their site which shows how to re-pressurize various models, so managed that quite easily and set it to just over 1.5bar. Will check it again in a week or so to see if its holding Ok but its certainly fixed the heat and noise problems for now
Regular falls can indicate a weep somewhere
And or a shagged expansion vessel leading to the pressure relief valve blowing it's guts out
This. You can normally see if it's been happening especially on a regular badis as it leaves marks on the wall and groundQuote:
