Bigger oil tank. Fill up in Summer?

Ha, this is a very good point. We've got a miserable 1200 lt and will be
faced with an expensive fill in January. Next stop a 3000 lt tank,
methinks.
Yes that would be a sensible option if you can eliminate the risk of
theft. £2000+ worth of black gold sitting in a big tank in your garden
is an open invitation. It would take minutes for anyone equipped with
a large tank on a flatbed with a pump to drain and once theirs was
full they'd let the rest spill on the ground. Or they might be clever
and have a sign written box van with the tank stowed away inside out
of sight.

And there's no point having a lockable cap, because they just punch a
hole in the tank.
