Whilst someone has mentioned these horrible things, I have to specify a
radiator to hang off one:

Wall does have an advantage - dog legs:

RRR is the rad.

Wall is 2.4m high, stops at the ceiling (and is not connected to
anything above except by virtue of being a tight fit to the plasterboard).


Is there a rule of thumb for how heavy and how high a load may go?


If the wall were not crap I would put in an 1800mm high vertical rad.
But the top fixings would be on the 2nd course and I don't trust that
not to pull the top over.

Hence the question

There's not very much "moment" even with a heavy radiator (as long as
someone does not try to climb it like a ladder). I think you are
worrying unnecessarily, especially with your dog-leg (provided the
blocks are properly laid to key the walls together). It is probably
worth using a reasonably long fittings. I've never used Multi Monti's in
lightweight blocks, but they might work well, perhaps using a drill 1/2
mm smaller than you would use with normal blocks or bricks.

Hiya,

I always like to factor a little abuse in (visiting little kid, someone
hanging heavy wet coats on it etc)

Can confirm that:

That's properly coursed around the corners.

That much I do have an answer to (having fixed to the other side of this
for bog cistern and free hanging basin):

I'll either use resin fixings 3/4 the way through the wall or these bad
boys:

(which I have used before). The wall will come down before they let go!


I guess you're right - it's just before that wall was plastered, I
chased it for conduit and the top block jumped off its mortar, so my
confidence went through the floor.

I'll probably aim for 3rd course from top - there's a lot of
interlocking at that stage.


Thanks mate!

I was worried as you hear the odd story of gable end walls falling over
after someone hung a boiler on the inside, or occasionally due to very
high winds...
