There are district heating projects in the UK, eg:

You can see some of the pipes at the eastern end of the railway station,
and others were re-routed a little south of the station as part of the
tramway extension works.

IIRC this system utilizes the Great Central tunnels under Nottingham.
Great as the heating system is, I would much rather have the trains,

That's one of many limbs to the system. The problem with reinstating the
trains is orders of magnitude more complex than moving a few hot water
pipes. Most recently the tram extension, and before that this absurdly
ugly museum in the tunnel mouth:

And of course the Victoria Centre and housing above, which is probably
one of the recipients of the hot water.
