Our picks

Best overall: Dimplex Rugged 3kW Workshop Fan Heater RUG3TS (£70.00). Dimplex designed the Rugged for workshops, garages and sheds. It has steel fascias, up to 3kW output with 2 heat settings and an air inlet filter for dusty conditions that can be cleaned with a vacuum. Built-in carry handles, overheat protection and a tip-over cut-off switch are included, and Dimplex offers a 3 year guarantee with registration.

Best value 3kW: Benross 42450 3000W Industrial Fan Heater (£49.99). Benross's industrial heater has 1500W and 3000W settings with an adjustable thermostat, a cool air setting and a tilting design to aim heat where you work. The listing estimates around £1.02 per hour at full 3000W, based on a 34p per kWh price cap, and it has an insulated carry handle.

Best budget: DAHTEC 2000W Portable Ceramic Fan Heater with Thermostat (£29.74). The cheapest pick uses a 2kW PTC ceramic element and delivers up to 142m3/h of warm air, rated for spaces up to 20m2. It has a 25W fan-only mode, 1kW and 2kW settings and a separate thermostat dial, inside a powder-coated steel housing with overheat protection.

Best for a converted garage: De'Longhi Capsule You & Me Oscillating Ceramic Fan Heater 2kW HFXR40T20 (£37.99). If your garage is a gym, office or hobby room, De'Longhi's Capsule adds comfort features: a 2kW ceramic element on a motorised oscillating base, suitable for rooms up to 60m3, an LED display, remote control, 24-hour timer, Eco function and thermostat. Safety features include a child lock, tip-over switch, thermal fuse and safety thermostat.

What to look for in a fan heater for garage

Output: garages lose heat fast, so 3kW models give the quickest warm-up; 2kW suits a smaller single garage or shed.

Tough build: steel housings handle knocks better than plastic, and an air inlet filter helps in dusty workshops.

Thermostat and settings: a thermostat and lower power setting reduce running costs once the space is warm.

Safety: look for overheat protection and a tip-over cut-off, and keep heaters clear of fuel, paint and sawdust.
