The best oil filled radiator for a conservatory has enough output for a room with lots of glass, which loses heat quickly on cold days. Many conservatories are not connected to central heating, so a portable oil radiator is a common way to make them usable from autumn to spring. Oil radiators give steady, quiet heat that carries on for a while after the thermostat clicks off, and a timer helps warm the room before you sit down.

What to look for in a oil filled radiator for conservatory
Output for the space: conservatories lose heat through glass, so choose a radiator rated for at least your floor area; 2000 to 2500W models cover larger rooms.
Thermostat and settings: a thermostat with several power levels stops the radiator running flat out once the room is warm.
Timer: a 24-hour timer lets you warm the conservatory before you use it rather than leaving it on all day.
Safety and mobility: tip-over and overheat protection plus castors make it easier to move between conservatory and house.
