We're looking at houses a little off the beaten track and some of them have a gas/oil tank in the garden. We've never had one before, so what (oh wise MNers) do we need to know?
Is it really expensive?
Do you have to be in for the deliveries?
Are there different sized tanks, what's a good family size?
We don't want to disregard these houses but don't want to jump in without knowing a bit more about it.
