heating conservatory

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.

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 =A3200 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!
