High Energy Bills

Heating accounts for 42% of home energy costs - the largest energy expense in most American homes.*

Poor Air Quality

Dust and allergens circulating through your home. Plus, that dry winter air everyone hates.

Life changing for my cabin

Primary heat source in my cabin had been a wood stove. I have had 5 Kelvin panels installed for a year now and they have made such a difference for me. They now hold the preferred temp in the cabin (currently 16 F outside, 70 inside!) and I supplement with the stove during the day, when at home.

It works nicely!

I was a little skeptical, but the large kelvin panel is working beautifully in a large, chilly room. After a little time to warm things up, it has been keeping the room at a steady and comfortable 68 degrees F. Will probably buy a couple more for other locations in the house.

Excellent Heating Source

We are using our new Kelvin in the Master Bath. It provides an excellent source of radiated heat in the room for when we wake up, as we like to sleep in cool temperatures and that room was cold before we got Kelvin. The app is easy to use and provides tons of flexibility for scheduling, and general operation. We love it!
