Every house has one room the furnace forgets

The bathroom at the end of the hall, the kid's room over the garage, the office where you work in a hoodie. Turning up the thermostat makes the whole house too warm while that room stays cold. Kozwall goes on the wall of that one room and heats it on its own, so the rest of the house stays where you set it.
WILL IT ACTUALLY WARM THE ROOM?
Small on the wall. 1500 watts into the room.

A heating element behind the bottom grille and a fan that pushes the warm air down and out. Fan only, 750W or the full 1500W, rated for rooms up to 215 sq ft — a bedroom, a bathroom, a home office. It's built for one room, not an open-plan floor, so put it where the cold actually is.
Off the floor, with a towel rack built in

No box on the rug and no heater by the blankets. Hook it over a towel bar with no tools, or drill 2 holes 6 inches apart — the plugs and screws are in the box. It sticks out under 5 inches, and the fold-down rack keeps a towel warm for after the shower (fold it down before you switch on).
WHO IT'S FOR
Three cold rooms, one fix
In buyers' own words.
"The bathroom at the end of the run was always an icebox"
Switch it on from the remote before the shower and step out into a warm room, with the towel already on the rack.
"Her room is always the coldest room in the house"
Heat the kid's room on its own, set the timer at bedtime and it switches itself off. Up on the wall, away from blankets and toys.
"A third-floor office that gets chilly in winter"
Warm the room you work in without heating the whole house all day.
Everything in the box
HOW IT WORKS
Plug. Mount. Warm.
A fan heater sized for one room.

Heat behind the grille
A heating element sits behind the bottom grille.
A fan pushes it out
Warm air goes down and out into the room — fan only, 750W or 1500W.
It looks after itself
Timer from 1 to 12 hours, child lock, and an overheat shut-off at 149°F with a 30-second fan cooldown.

ANY LAST QUESTIONS?
The things people ask before they order
How big a room will it heat?
Kozwall is a one-room heater, rated for rooms up to 215 sq ft — a bedroom, a bathroom, a home office. It isn't made for a large open-plan space.
Do I need tools to put it up?
No tools if you hook it over an existing towel bar. To mount it on the wall, drill 2 holes 6 inches apart — the wall plugs and screws come in the box. It plugs into a standard outlet with a 6 ft cord.
Can I use it in the bathroom?
Yes. Mount it at least 71 inches above the floor and at least 25 inches from the tub or shower, and fold the towel rack down before you switch it on.
Is it loud?
It runs under 50 dB. You'll hear a soft fan, and after you switch it off the fan runs about 30 seconds to cool down. The remote has a silent button and a display-off button.
Can I set it and forget it?
Set the timer for 1 to 12 hours and it switches itself off. The child lock stops anyone changing the settings.
What if it stops working or breaks?
If it isn't the heater you hoped for, or you're unhappy with it for any reason, message us through the Contact page within 30 days of delivery and we'll walk you through a return and a full refund.
