Well I had an engineer round today to look at my dodgy Potterton Puma 80 - as I feared the expansion vessel has died. Replacement from them is £100 + vat, on the net it's £63 +vat so that's more tempting.
However, the manual recommends an external expansion vessel be fitted 'in the unlikely event of failure', and these are much cheaper - £25 or so. I told the guy I'd get one of those and he'll come back to fit it and service my boiler..
Problem is the 12litre one is too wide to fit in the cupboard below the boiler, the 8litre one would fit fine - HOWEVER, the one it would replace is 10litre. Would this cause any problems? I'm thinking/hoping that it won't, as I'm running 7 rads in a fairly small flat, and that 8 litres ought to be enough (and if not, it'll just mean that the pressure when CH running is slighly higher than it would otherwise be and not too much of a problem?)
Thanks in advance!
PS It's amazing how much terminology I've picked up over the past few days from checking out this forum to help with my boiler problems - never heard of an 'expansion vessel', 'prv' etc before then
