Space Heaters Buyer's Guide
Power source
Electric fan and oil-filled radiators plug in anywhere. Propane and kerosene heaters output serious BTUs but need ventilation. Infrared panels are silent and wall-mountable.
Heat output (kW / BTU)
1–2kW (3,400–6,800 BTU) warms a small room. 3kW+ (10,000+ BTU) heats workshops and large conservatories.
Safety features
Tip-over cut-off, overheat protection and oxygen depletion sensors (for fuel-burning models) are essential.
Running costs
Electric is expensive per kWh but 100% efficient at point of use. Propane is cheaper per unit but needs cylinder swaps.
