Cheers for all the replies, i will try this! The thing that scared me
was that whilst i knew the Central heating wasnt working and not to
turn that on, i didnt realise that we'd have no hot water!

I hope that pump didnt run dry too long! It was making a thumping
noise and got very warm! I thought that the hot water for your tank
was mains fed (off teh main cold water tank)... How would I have
introduced air into this (seperate?) system!

What do you mean by "no hot water"?

When you open a hot tap, do you get:
* water, but it's cold?
* nothing?

If the former, this is to be expected because the water from the boiler
circulates through the indirect coil in the hot water cylinder to heat the
water. No working boiler/pump= no hot water.

If the latter, you've clearly got more than one problem!
