Oh, and a bit of heat.

Yes - that expresses my understanding of it.

You could just run narrow bore pipes from the central heating up and
down along the cupboard tops, creating a sort of radiator.

Yes - this exact idea had occurred to me! I may still do something like
that. When you say 'narrow bore' do you mean something less than 15mm? If
so, why is that better than 15mm? Is it a more efficient way of doing it
somehow?

Thinner pipes give more surface area to radiate.

I see your point now - although it's electrically-produced heat which of
course is more expensive than gas-produced heat at present, and arguably
likely to remain so. More of a concern is perhaps the fact that the heaters
are on the floor (in my case a solid one). Would that not result in a lot
of the heat radiating into the floor, never to return?

They blow it out the front like a fan heater - so most will rise...
