I
let the oil run out a couple of weeks ago while waiting for price to
drop. Got a fill of oil and thought I'd just have to bleed the boiler,
but no air and oil escaped from the bleed vent when unscrewed. Checked
the filter at the tank and it's not blocked. So fine sludge has probably
got through the screen mesh of the filter and perhaps blocked the
pre-filter in the boiler. So hopefully the oil line won't have to be dug
up, because it's under concrete, and the boiler service people can just
clear the line with compressed air or flush it. Anyway it's more
expense. Moral of the story, check your oil regularly. I always do, but
just let it down a bit far while waiting for price to drop.
