Best Oil-Filled and Radiator Space Heaters Ranked

10 oil-filled, oil-free and convector heaters with no fan.

Last updated: October 30, 2026

A radiator heater warms its fins or panel, which warm the air that rises past them, and that slowly circulates heat through the room with no fan at all. It’s silent and doesn’t blow dust around, which makes it the usual pick for bedrooms. It takes 20 minutes or more to warm a room, and an oil-filled radiator keeps giving heat for a while after it switches off. The sealed oil is never burned or refilled; it only stores heat.
