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

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.
