Questions people ask
- What is a ceramic heater?
- A heater that passes electricity through ceramic (PTC) plates. The plates heat quickly and limit their own temperature, and a small fan moves the warm air into the room.
- Are ceramic heaters safe to leave on?
- Look for overheat protection and a tip-over or automatic shut-off. Even then, don't leave any heater running unattended or overnight, and keep it clear of curtains and bedding.
- Are plug-in ceramic heaters cheap to run?
- They cost the same per kWh as any electric heater. They save money by warming a single room quickly and, with a thermostat, switching off once the room is warm.
- What size ceramic heater do I need?
- Compact plug-in ceramic heaters suit small rooms up to about 12 m². Larger or draughty rooms need a more powerful heater.

Perfect for my cold office
I have a small office with a door that gets really cold because the building management keeps the winter temperature far too low for comfort. I plugged this into the socket above my desk and now I am warm without anyone even knowing it is there. I love it.
Great in the bathroom
We use it to take the chill off the bathroom before the kids' bath time. Warms up fast and the timer is handy. Four stars only because I wish the display were a little dimmer at night.
Worth being straight about: RapidHeat is built for rooms up to about 12 m². It is not a replacement for central heating and it will not transform an open-plan lounge or an uninsulated garage. If it is not right for your room, send it back within 30 days.
