I Turned My Furnace Down to 58. Then the Power Company Sent Two Men to Check on Me.

My electric use fell 60 percent in one month. The co-op thought something was wrong. Here's what they found hanging on my kitchen wall.

My kitchen. The furnace is set to 58. The thermometer on my table says 72.

It was a Tuesday, just after dark.

Two men in co-op jackets were standing on my porch.

"Ma'am, is everything okay? Your meter's barely moving."

I'm 74. I live alone. I suppose that's what worried them.

I told them to wipe their feet and come see for themselves.

They stopped dead in my hallway

The thermostat on the wall said 58.

My hallway thermostat. It hasn't moved since October.

The thermometer on my kitchen table said 72.

The younger one looked at me like I'd pulled a rabbit out of a hat. "Then where's the heat coming from?"

I pointed at the flat white box hanging over my kitchen table.

"That's doing all of it. The furnace is just keeping the pipes from freezing."

I was paying to heat rooms nobody was in

My husband passed four years ago. Since then it's been me and a four-bedroom house.

Last January my electric bill came to $412.18. On a teacher's pension. I nearly dropped it.

So one night I walked through the house and counted.

Kitchen in the morning. Living room in the afternoon. Bedroom at night.

The guest room. The hallway. The laundry room. The stairs to the basement.

I was heating every one of them, all day long, for nobody.

A furnace doesn't know you're sitting in the kitchen. It heats every room on a schedule, pushes air through ducts that leak, and the warm air floats up to ceilings nobody sits under.

And the meter spins the whole time.

The trick isn't heating less. It's not heating the rooms you aren't in.

My granddaughter hung it up in ten seconds

Kayla found it. She saw it on Facebook and ordered one for me, which I told her was a waste of money.

It weighs 2.7 pounds. About the same as my good cookbook.

Two hooks come in the box. She hung it, plugged it into the outlet that was already there, and pressed the button.

Warm air in about three seconds.

I didn't believe it. So I put my kitchen thermometer on the table. It read 49 that morning.

In under a minute it passed 80.

I ran it ten more times to see if it was a fluke. It wasn't.

From the company's video. Up on the wall in six seconds.

You set it anywhere up to 113 degrees on the touchscreen, or from your chair with the little remote.

One heater covers a room up to 549 square feet. That's my whole kitchen and half the dining room.

It uses less power than my hair dryer

The older lineman said what everybody says. "My space heater trips the breaker every time my wife runs the microwave."

Most space heaters pull 1,500 watts.

This one runs on as little as 400. Its top setting is 800.

400Wlow setting, less than a hair dryer

549 sq ftcovered by one unit
2.7 lbwall or shelf

The secret is inside. It has a ceramic core, the same kind of material electric cars use to keep their batteries warm in winter.

The hotter it gets, the less power it pulls. A fan draws the cold air through and pushes warm air out, so the room warms in seconds, not twenty minutes.

Fan, ceramic core, control board. No flame, no oil, nothing to maintain.

On low, it costs me about 55 cents a night. Less than the tea I drink under it.

And it's not a little warm. I put a second one over my bed. The quilt that used to be up to my chin is folded at my feet now.

Up on the wall, where little hands can't reach

I never trusted the old floor heaters. The cord across the rug. The hot box right at toddler height. The night my neighbor's dog knocked hers over.

This one hangs up high, out of reach.

Kayla does her homework on my couch right underneath it.

It's whisper quiet, it doesn't glow, and it shuts itself off if it ever gets too hot.

I stopped worrying about it the first night.

Then my bill came

My first bill after I turned the furnace down was $164.80.

The January before, it was $412.18.

That's $247 back. In one month.

$412my January bill
$165my first bill with Cozy Cove
$247back in one month
$1,200+back over one winter

That's more than twice what I paid for the heater. In the first month.

The linemen asked where I got it. Not the hardware store. The big stores don't carry it.

It's only sold on the company's own website, and it keeps selling out. My neighbor Doris missed the last batch by one day.

The younger one ordered two right there at my table. One was for his mother.

Why I didn't buy the $49 one

Kayla showed me the cheap little cube heaters on Facebook too. $49, half the price.

My friend Phyllis bought two of them. They hum, they get hot to the touch, and they warm about one chair.

So I made a list, the way I used to for my students.

Trips the breakerNever hasTwo of them will
RemoteYes, plus touchscreenA dial
Money back90 days30 days, if any
Today$99.99 $199.98$49

To heat my kitchen with the little ones, I'd need four of them. That's $196 and four cords across the floor.

One Cozy Cove heats my kitchen and half the dining room. For about the price of two of the cheap ones.

I put my bill on Facebook. My phone hasn't stopped.

Kayla told me to post the two bills side by side. Half of Dayton has seen them now.

Linda KowalskiMarge, is this the thing you had in the kitchen at book club? I thought it was a fancy air conditioner.

What it costs to stay warm this winter

Before the linemen left, I sat them down at my kitchen table and showed them the math I did in October.

It's the part most people skip.

$400-800an electrician to wire one baseboard heater
$60-120a hardware store heater that pulls 1,500W
55¢a night to run Cozy Cove Pro on low
$247back in one month on a $412 bill

No electrician. No install. Nothing to maintain.

It hangs on two hooks, plugs into the outlet already on your wall, and it's warm in three seconds.

And if your room isn't warmer, you send it back inside 90 days and get your money back.

It normally sells for $199.98. Right now it's half that.

Warm in my den in a minute

I hung it over my recliner. The house thermostat is on 60 and I watch the ballgame in a T-shirt. Electric bill was $298 last December, $131 this November.

Finally warm at night

I'm the one who is always cold. I set it to 72 an hour before bed and turn the furnace down. Best hundred dollars I've spent in years.

Better than the cheap ones

I tried two of the little $49 heaters first. They hum, they get hot to touch, and they barely warm a chair. This one is quiet and heats my whole kitchen.

One for the kitchen, one for the bedroom, one for the sunroom. We closed the vents in the rest of the house. Our bill is about half.
