Plug-In Heater for Any Room – RapidHeat Wall Outlet Heater

What is a plug-in heater?

A plug-in heater is a compact electric heater that plugs directly into a wall socket. It's designed to warm the space around you, such as a bedroom, office or bathroom, without heating the whole home.

How a plug-in heater works

Inside RapidHeat are ceramic (PTC) heating plates. When electricity flows through them they warm up within seconds. A small fan pushes air across the plates and out into the room, so you feel warmth quickly instead of waiting for the air to warm up on its own.

Because the heater sits on the socket, there's no cable trailing across the floor and nothing to knock over. That makes plug-in heaters popular in bedrooms, hallways, home offices and anywhere floor space is tight.

Plug-in heater vs regular space heater

Most floor-standing space heaters draw 1,500W or more. That's great for a big room, but it's a lot of power to heat one person at a desk. A plug-in heater like RapidHeat uses 400W or 800W, so it costs less per hour to run and is better matched to small rooms.

The trade-off is honest: a plug-in heater won't replace central heating for a whole floor. It's designed to keep the room you're in comfortable while the rest of the house stays cooler.

Where people use plug-in heaters

Bedrooms, warmed before bed with the timer set
Home offices and desks during the working day
Cold hallways, entryways and spare rooms
Rentals and student rooms where you can't install heating
Basement rooms, craft rooms and workshops (dry areas only)

Getting the most from your plug-in heater

Close the door so the warmth stays in the room. Start on High (800W) to warm up quickly, then switch to Low (400W) or let the thermostat hold the temperature. Use the timer so it switches itself off when you leave or fall asleep.

Choose an outlet that's not behind furniture or curtains, so air can flow freely in front of the heater.

How many heaters for your room?

A rough guide for topping up a home that has some heating. Cold, high-ceilinged or poorly insulated rooms may need more.

Room size	Typical room	RapidHeat units
Up to 250 sq ft (≈23 m²)	Bedroom, office, small living room	1
Up to 500 sq ft (≈46 m²)	Living room, large bedroom	2
Up to 750 sq ft (≈70 m²)	Open-plan or draughty room	3
Larger spaces	Alongside your main heating	4

What it costs to run

Maximum cost at full power, for common electricity prices per kWh in your own currency. With the thermostat cycling off once the room is warm, real costs are often lower. Try the energy cost calculator with your exact price.

Price per kWh	Low 400W / hour	High 800W / hour	High, 4 h a day / month
0.15	0.06	0.12	14.40
0.25	0.10	0.20	24.00
0.35	0.14	0.28	33.60

Who RapidHeat is not for

We'd rather you buy the right heater than return the wrong one. RapidHeat isn't the best choice for:

Heating a whole house or open-plan floor on its own
Large rooms over about 250 sq ft (≈23 m²) with just one unit (use two or more)
Bathrooms or anywhere it could get splashed with water
People who want silent, fan-free heat (try an oil-filled radiator)

Common questions

Does a plug-in heater use a lot of electricity?

It depends on wattage and hours of use. RapidHeat uses 400W on Low or 800W on High, which is far less than typical 1,500W+ space heaters. Use our energy cost calculator to estimate your own cost.

Can a plug-in heater heat a whole room?

Yes, for small to medium rooms. RapidHeat is designed for spaces up to about 250 sq ft.

How much does RapidHeat cost to run?

At full power RapidHeat uses 0.4 kWh per hour on Low (400W) or 0.8 kWh per hour on High (800W). Multiply that by your electricity price per kWh. At 0.25 per kWh that's 0.10 per hour on Low and 0.20 per hour on High. The thermostat cycles it off once the room is warm, so real use is often lower.

What size room will one RapidHeat heat?

One unit suits rooms up to about 250 sq ft (≈23 m²), such as a bedroom, home office or small living area. For bigger or draughty rooms, use two or more units in different parts of the room.

Is RapidHeat safe?

It has overheat protection, automatic shut-off and a thermostat. As with any heater, plug it directly into a wall outlet, keep about 1 m (3 ft) clear around it, never cover it and keep it away from water.

Do I need an extension lead?

No, and you shouldn't use one. RapidHeat plugs straight into a wall outlet. Extension leads and power strips can overheat with any heater.

Can I leave a plug-in heater plugged in all the time?

It's best to switch it off and unplug it when you leave the house or aren't using the room. Use the timer to switch it off automatically.
