3.5 x 3m conservatory what size electric heater will heat this room on
a winters night, it is one of those pentagon shaped conservatories.

Is convection or oil filled the best, I dont really want a fan heater.

3.5 x 3m conservatory what size electric heater will heat this room on

Full height or dwarf wall?
Dwarf wall insulated?
Double glazed or single?
Roof glass or polycarbonate?
Polycarbonate roof double or triple wall?
Glass roof double glazed?

Convection quicker and more effective, especially with fan boost for rapid
warmup.
Oil filled safer.

Both equally inefficient with the world's resources, so use sparingly and
only use devices with thermostatic control. If you have gas CH, leave the
door open into the house, as this is more efficient.

You shoudl get away with about 2kW, although 3kW will bring it up quicker.
Make sure it is thermostatically controlled and it is preferable to open the
internal door to get the benefit of the house central heating, assuming you
have gas or oil.

couldn't you add a rad from the house CH ?

obviously more expensive (much cheaper if you DIY) and cost effective
in the long run.

sub £200 for a DIY number :-)

It is feasible to add another zone to your existing central heatingsystem,
and put a normal 'wet' radiator in the conservatory? Assuming you have a gas
fired system, this would be the most efficient solution.

This is certainly going to be less expensive to run than electric
heating in the conservatory. It is supposed to be a separate zone or
have thermostatic control valve on the radiators.

I'm not sure of the legalities but, from from a practical point of view, it
really needs to be a separate zone. If you simply have a rad on the main
circuit, with a TRV, there's no possibility of heating *just* the
conservatory.

OK, yes, but then why would one want to heat just the conservatory?
If that were the intent, wouldn''t it also be logical to make each room
a separate zone with thermostat and timer?

The conservatory has a much lower thermal inertia than the rest of the
house - and may well be cold when you want to use it even though everywhere
else is ok. It may also be useful to be able to specifically *not* heat the
conservatory without having to go and physically turn its radiator off. That
may be rubbish, but that was my thinking!

OK, fair points.
