Our oil tank used to sit up high on concrete blocks, however we were
recently advised by the man who serviced our boiler that we could
happily site the oil tank on the floor and the boiler would pull the
oil through. This we have done - we were having some ladnscaping done
and took the opportunity to move it slightly and put it on slabs - this
was done by the landscapers.


An indication of the relative levels before and after also the length of
pipe and size would enable us to get an idea of what is involved. Also
whether the tank is empty or full or somewhere between.

I have just tried to bleed the boiler (something I have done before
myself) but with no success. I phoned another heating engineer who
told me that my boiler must be gravity fed and the tank shouldn't sit
on the floor - I'm inclined to agree with him and think I was badly
advised first time.

Maybe but there are a hell of a lot of chancers out there. I get very
depressed by the state of some of the "jobs" I come across, supposedly
installed by professionals. Most of the problems can be readily overcome by
simple application of o level physics but this is apparently beyond some
installers.

My boiler is a trianco and the burner is Riello/RBL.

Nothing wrong with either of those.

The new chap is suggesting putting in a different burner as you cannot
fit a different pump to the burner I've got. He can fit a recon one
for £200. This seems fair to me and I think is what I'm going to go
for.

Hes a chancer trying to take money from your pocket and pout it into his!
forget it and look at the problem from an engineering viewpoint.

I would be grateful for opinions on this in case I am being badly
advised again. I could go and argue the toss with the original man who
advised me in the first place, but I don't think I will have a leg to
stand on.

Assuming your tank fuel level is above the burner the pump should prime if
the pipe is not blocked or kinked. You could find a problem if it is
restricted by kink or its size/length but without the info I asked for first
its not possible to say with confidence. If the tank fuel level is below the
burner it will not self prime and you will need to intervene manually to
achieve priming. In extreme cases it might be neccessary to employ a
dearator device but give me the info first.

BTW where are you located?
