We'll do this once we turn the heating on.

Kevin Holland It's a lot easier bleeding the rads when the liquid in them is cold, not piping hot. I tend to do it whilst heating off, then when heating on, check for cold-tops on the rads that indicate if I need to do it again.
Still, now I've turned down flow temp it's easier!

No Sheds Have you met my mate Heatkeeper ?

And where possible, put a small shelf above the rads. It forces the warm air into the room, instead heating from the ceiling down.

I've met ppl who use a USB powered fan to push warm air to where they sit! Like we're doing, right now!
