Depending on model and year then.
Get your model number and ring

Excellent. I've found the feed pipe
round the back of the store now so
I think I'll be able to re-use it. Would
it be worth using the store
just for hot water and having the CH
straight off the boiler?

If the header tank is on the ground floor then no, as the F&E tank has to be
higher than the rads. If the header tank can be higher than the boiler, get
an open vented "heating boiler", and use a plate heat exchanger off the
BoilerMate for the CH, which will get the rads over the header tank. Only
the CH circuit on one side of the plate will be pressurised.
