Everything you want from a heater, and nothing you don't
No glowing bars, no 20-minute wait, and no paying to heat empty rooms.
Heat where you sit
Warm the room you're actually in, turn the house thermostat down a notch, and see the difference on your next bill.
Room to room
At just 0.5 kg it goes wherever you go: the lounge in the evening, the bedroom at night.
Quiet by design
No ticking, no clicking, and none of the burnt-dust smell you get from old bar heaters.
Peace of mind
Safe for Mum and Dad, the grandchildren and the dog
Many families buy the K1 to replace an old bar fire. There are no glowing bars and nothing red-hot to touch. If it's knocked over, it switches itself off.
- Switches off instantly if tipped over
- Switches off if the vent is covered
- Casing stays cool to the touch
- Light (0.5 kg), so no heavy lifting
- Remote control, so no bending down to the floor
Heat the room you're in for about 16p an hour
Instead of running the boiler for the whole house, keep the room you're sitting in cosy and turn the central heating down a notch. That's where the savings come from.

Warm air across the whole room, not just in front of it
Warmth spreads along the floor first, then rises to fill the room. Here is the same small heater from three angles.
From the floor up
Warm air spreads across the carpet first, where your feet are.

Warm before you get in, then the thermostat holds it.

Most cheap fan heaters blow air over a glowing metal coil. They're slow to warm up, they scorch the dust in the air, and they keep drawing full power whether the room needs it or not. The K1 uses a PTC ceramic honeycomb instead. As the ceramic gets hotter, it automatically draws less power.
01
No exposed heating wire
The element is sealed inside the ceramic, so nothing glows and nothing scorches.
02
Self-limiting by physics
Ceramic draws less current as it heats, so it can't run away with itself.
03
Even, gentle warmth
Air passes through the whole honeycomb rather than over one hot spot.

How big is it?
About the size of a shoebox, and it weighs just 0.5 kg. It fits on a side table, a desk or the floor, and it's easy to carry from room to room.
How many do I need?
One K1 heats one room of up to 20 m². Tap the rooms you'd like to keep warm.
We recommend 2 × K1 Heaters for £89. That's £44.50 per heater. We've selected it for you.
