Don't install one that is overated - our house has 16 rads/hot water

Unless it supplies a shower and it's a combi boiler and you want a
good flow of hot water.

I'm talking about a system boiler heating an unvented cylinder. In our
three story house the pressure is good enough for a very good shower on
the top floor.

Anyway just had the engineer in and he couldn't fix our old Vaillant. He
didn't have both PCBs on the van but the minimum cost to fix would be
about £300-£350 assuming one board would fix it and if both boards are
implicated that's about £500.

So I've asked him for quotes on a new 28kw (his suggestion) Vaillant and
Ideal, which he says he can fit on Friday or Monday.

At least i didn't have to pay him tonight as no fix no fee.

Might be worth giving Geoff at CET ltd a call to see if he has
re-manufactured PCBs for the boiler (basically he does PCB exchange -
you buy recon ones, and send him the dead ones - at a fraction of the
price from the OEM)
