Friend of mine has a leaking HW cylinder. They have a very expensive
maintenance contract with BG so they have rung them up to come and have
a look at it.

"Oh you have got a very funny tank - its got 2 coils in it."

"Yes we know it has 2 coils, one is for the Gas the other is for the
back boiler behind the open fire in the lounge."

"It will take us ages to get hold of a cylinder of that size with 2
coils can you live without the back boiler?"

"Well yes its never been used since the gas was installed."

My question to the group, if you drain all the water out of a back
boiler system, does that preclude using the open fire? IE will you
melt/damage/distort the fireplace/boiler?

I don't think it will bother them if the answer to the question is no
you cant use the fire - as it has not been used in 25 years - but they
would like to know if it MUST not be used rather than they choose not to
use it.
