Even though the weather is pushing toward a balmy 40℉ in much of the U.S., it’s been a long, cold winter for much of the country. If you’re one of the tens of millions of people who live in an apartment with steam radiators, however, you may have had your window cracked open in sub-freezing temperatures because your radiator made your apartment feel like a sweltering jungle.

Whether you’re an uncomfortable tenant or a building owner of one of these aging edifices, you may not know that there is an emerging solution to the problem. Not only can it make apartments much more comfortable, but new data suggests the technology can cut boiler runtime by up to 20 percent, according to a recent pilot by Radiator Labs.

Radiator Labs is a new startup out of New York City, which has the highest concentration of buildings that use steam heat. The solution is a giant cozy with a fan that goes over the radiator in the room.
