So, you can probably now guess where I am going with this...

The present thought is to install wall radiators in the conservatory
plumbed via a
zone valve to the central heating system.
The zone valve being timer operated via one of those immersion-heater
timer devices
that have a maximum delay of a few hours.

At the same time, install my proprietary underfloor heating but plumb
this permanently
off the central heating system.

Thus under normal circumstances the underfloor heating ought to keep
the conservatory
comfortably above freezing, but when you need it you can kick into life
the wall
radiators.

Any thoughts on my scheme ?


Quite reasonable. UFH with a concrete floor is relatively slow to
react because of the heat capacity of the concrete. However, if you
adjust it seasonally it should be reasonable.

There does need to be an additional zone for the UFH to comply with
building regulations, because you need to be able to show that it can
be turned off.
