A one-car garage, a garden shed or a small workshop of 150–250 sq ft does not need a 240V heater. A rugged 1500W, 120V heater that plugs into a standard outlet can keep the area around your workbench comfortable, as long as it is built for dust and knocks rather than a living room.
We compared garage-ready 120V heaters by build, heat output, thermostat control, mounting and safety using manufacturer specifications and owner feedback. For scored tests see our space heater for garage for small room reviews; our Editorial Policy explains our process.

Buying Guide: Heating a Small Garage
- Plan about 10 W per sq ft: a 150-sq-ft insulated garage suits a 1500W heater.
- Plug straight into a wall outlet; never use a light-duty extension cord.
- Keep heaters away from gasoline, paint thinner and sawdust.
- Use a carbon monoxide alarm in attached garages, especially if a car runs there.
