20 or 30kg is liftable.

Sometimes its the awkward place they need to go that makes it hard -
i.e. often working above a kitchen worktop, between cupboards etc when
you can't really get under it or even get a good grip on it. I did one
like that, right in the corner of a kitchen and although it was not that
heavy in absolute terms (about 35kg) there was no way to actually get it
in place directly. So in the end I stacked up a few power tool cases on
the worktop, sat the boiler on them so that it was an inch higher than
the wall bracket, and pushed it back against the wall. Hanging it was
then just a job of keeping it against the wall, while pulling one of the
tool cases out from under it so that it dropped onto the bracket.

Have I seen an advert for some sort of block and tackle arrangement?
Screw it to the wall. Lift the boiler into place safely, then unscrew it
again.


(It can be more fun getting the old ones out - the Mexico I took out of
here was something like 96kg! (fortunately I had it on a long rad in the
back of the car, so when I had to offload it at the scrappie, I had
something that would slide out easily, and also gave a bit of mechanical
advantage to the end that needed lifting).

Can you lift 96kg? Otherwise, how did you get it into the car in the
first place?
