I have lived alone in a three bedroomed association house for 17 years
and now there is a plan to replace all the storage heaters with a hot
water system. This seems to be initiated by a government directive to
make home heating more efficient by using a heat pipe. Any efficiency
gain would obviously be lost by transmitting heat using water, rather
than direct electricity.
I am proposing that the installation of new radiators are fitted behind
inward opening doors in the bedrooms and living room, this is all dead
wall space and doesn't interfere with existing fitments. The upstairs
landing will be housing the electric boiler and would facililitate short
runs of pipework to the bedrooms, making a cleaner, more compact job.

My wife, who lives in the next village has had such a conversion, but
with gas as the heat source instead of electricity. This keeps breaking
down and the (engineer) has to come out to fiddle with the boiler, at
least a couple of dozen times now since 2019.

Question: Does the team think that putting the heaters behind the doors
would have any detrimental effect on heat distribution. All the storage
heaters are under windows at the moment, so immediately lose a huge
amount of heat, although double glazed.

Best regards

The reason for radiators under windows is that you get a cold downward
draft from the window which even in a well heated room makes your feet
feel cold and you perceive that the room is much colder than it actually
is. Putting a radiator under the window counteracts this downward cold
draft.

If the housing association is proposing air sourced heat pumps then be
prepared for much larger radiators.
