Yes I've checked for air, there's none in any of them. What does "balancing them" mean?
I've just had a thought, that both the house next door to me and the one opposite have had new boilers and stuff in recent years, one I know has a pressurized water tank in the garage. I'll ask them if they made any pertinent discoveries next time I see them about. My system is original straight forward heat only gas boiler plus hot water tank, with cold water tank in the loft. Maybe the pipework was found to be protected when they did theirs and survived a pressure flush. These were particularly high quality build houses for the period, so there is hope. It is a single close of houses built off a tree lined avenue, on the site of an old Early Victorian "Hall", which had fallen into disrepair. Built by a small local company rather than a national builder, there are only 36 of them, and I've never seen the same design of these houses anywhere else - the main bulk of 60s/70s stuff in my suburb is a mile or two away on the other side of the valley and is pretty cheaply built shonky stuff, which stand in stark contrast to mine.
Perhaps a chemical clean at low pressure is an idea too, so thanks for that.

There's a cut-off on either side of a radiator and you'd normally adjust only one to turn up/down - manually or with a TRV if such a valve is fitted. But the flow into/out of the radiator is also controlled by the other valve. So you tune the system to balance the flow to all of the radiators. You turn it down on some to make sure there is enough heat for other radiators.
When the heating is on, does the pipe leading into the radiator get very hot but then does not heat the radiator itself? Do you know how the pipe work feeds the various radiators?
My mum's old house had an unusual place for the bleed valve for a radiator in the lounge. It was at the end of a pipe in the bedroom above, just behind the wardrobes! But the house dates from the mid 1800s and so the heating was put in in the 60s.... And the pantry was knocked through into the lounge around then and an extra radiator installed... plumbed off the pipework in the bedroom above.

Hmm. Bit above my pay grade all that. I might ask again in the autumn when the heating comes on again.

…assuming it does. Ours wasn’t going to.

Without the pressure clean I am sure WDBs heating would have come on.... and then in the coldest part of winter it would have failed. Or something like that.
Luckily you planned to go electric to save our planet.
I'm still pondering electric - I'd need to get someone out to check about solar panels. The biggest sloping roof is over the garage but that's a bit shaded by next door. Part of the main roof is four sided and therefore each side slopes and relatively small for panels. There is the roof above the main bedroom that is more normal too. And then I'd definitely want batteries but room in the garage for those.
The houees near us with panels have them on the side where our garage roof is... so we might not get much. Suppose I could borrow some of the land behind the house.
