Just a quick question please because I think I've read this somewhere but can't find it again.
With a combi boiler system, If swapping 3 single radiators to 3 double (effectively increasing the system capacity by 3 radiators worth) will the pressure vessel need repressurising?
Boiler has quite a variation in pressure between cold/hot and can't remember if it was already like it before changing the rads over.
Cheers
