THE WARM HOUSE JOURNAL
I was heating the whole house for one cold room.

That One Room the Furnace Never Reaches? Hang This on the Wall and It's Fixed.

Six reasons people with an icebox bathroom, a kid's room that's colder with the door shut, or a freezing home office are hanging a 13-inch wall heater — and turning it on from bed.

Reason #1

Every House Has One Room the Furnace Forgets. Yours Doesn't Have to Stay Cold.

You know which room it is. The bathroom at the end of the hall. The kid's room over the garage. The office in the back corner where you work in a hoodie from November to March.

The furnace runs, the rest of the house is fine, and that one room never catches up. So you nudge the thermostat. Then nudge it again. Now the whole house is too warm and the cold room is still cold.

One reviewer said the bathroom at the end of the run “was always an icebox.” Another said their son's room is easily 10° colder once the door closes at bedtime. Kozwall goes on the wall of that one room and heats it on its own. The rest of the house stays exactly where you set it.

i40 of the 180 wall-heater reviews we read are about that exact room — the one furthest from the furnace, the one with no vent, the one that's always cold.

Reason #2

Here's What It Actually Does. Fan, 750W or 1500W, Up to 215 Sq Ft.

Kozwall is a fan heater. A heating element sits behind the bottom grille and a fan pushes the warm air down and out into the room. Three modes: fan only, 750 watts, or the full 1500.

It's rated for rooms up to 215 square feet — a bedroom, a bathroom, a home office. The whole thing is 13 inches wide, 10.24 tall and 4.92 deep. It plugs into a normal wall outlet with a 6 ft cord. No electrician, no hardwiring.

The round touch display on the front runs everything, and so does the remote. If it ever gets too hot inside, it shuts itself off at 149°F and runs the fan for about 30 seconds to cool down.

iStraight answer on big rooms: this is a one-room heater. The most common complaint we read (12 of 180) was a wall heater bought for a large open space. Put it in a room up to 215 sq ft.

Reason #3

Off the Floor and Out of the Way. With a Towel Rack Built In.

A floor heater is one more thing in a small room. It sits on the rug, the cord runs across the walkway, and the blanket slides off the bed toward it.

Kozwall goes up on the wall. Hook it over an existing towel bar with no tools at all, or drill two holes 6 inches apart — the wall plugs and screws come in the box. It sticks out less than 5 inches.

Underneath sits a fold-down towel rack. In a bathroom, that means a warm towel is waiting when you step out. Fold the rack down before you switch it on, and the floor stays clear.

i39 of 180 reviews mention getting the heater up off the floor. One put it simply: it keeps the room cozy “without sacrificing precious floor space.”

Reason #4

Step Out of the Shower Into a Room That's Already Warm.

Picture the morning that usually goes wrong. Frost on the window. Hot shower. Then you open the curtain and the cold hits your wet skin all at once.

Switch Kozwall on from the remote before you get in. By the time you step out, the room is warm and the towel on the rack is waiting. One reviewer wrote that it means “no more dreading getting out of the shower into the cold.”

It runs quiet — under 50 dB — so the same heater works in a bedroom at night. The display light switches off from the remote for a dark room.

iStraight answer on noise: it's a fan heater, so you'll hear a soft fan. When you switch it off, the fan keeps running about 30 seconds to cool down, then stops.

Reason #5

Turn It On Without Getting Out of Bed.

This is the one buyers bring up most. The remote works from up to 16 feet away, so the heat comes on while you're still under the covers.

A big power button. A mode button for fan, 750W or 1500W. A timer from 1 to 12 hours, so it shuts itself off after you fall asleep. A child lock so little hands can't change it, a silent button, and a light-off button for the display.

One reviewer summed it up: a remote “so I don't even have to get out of bed to turn it on.”

i64 of 180 reviews mention the remote — more than any other feature we counted.
