In the fall of 2019, we built a greenhouse to overwinter tropical plants. We needed to find a heating
source for the freezing St. Louis temperatures. Gas and propane heaters would have been an extremely
difficult installation. Electric heat would be the easiest to install, but everything I had heard was that it
was the most expensive to operate. A local news program spotlighted Thermasi high efficient electric
furnaces. I called and talked to the owner Allen Coggins to see if he had a solution for my greenhouse.
The greenhouse is 15’ x 20’ x 8’ with an R value of 3, so keeping it heated to a minimum of 65 degrees
would be a challenge.
Allen invited me to come tour his manufacturing facility. He took the time to explain how his furnace is
different from all other electric furnaces and how that makes them more efficient. He designed and
built a unit specifically to meet my needs and made it easy for me to install myself. This past winter we
had temperatures as low as 6 degrees, and we had no issues in maintaining the 65 degrees temperature

In early 2019, I read an article about a new High Efficiency, Thermal Mass, Infrared furnace that Allen Coggins invented, and I wanted to know more. Knowing Allen from a business group years ago I decided to contact him to get the scoop and eventually drove to the COCOON offices to see for myself. After just a few minutes of looking into the Cocoon Furnace, I decided to have one installed at my home.
Before the COCOON System, I had a 1960’s era, a very inefficient gas furnace to heat my home. The other appliances had long before been changed to electric, and our utility provider would charge me $26+ per month, just to have the meter turned on. One April, during a threatened flood, our utility, pulled the gas meter to prevent potential damage. I did not ask them to reinstall it until October, saving me over $150 on my heating bill. So, the prospect of having no gas, and "gas safety issues" to deal with was exciting. Still, I knew that a typical “Electric” furnace would eat me alive in electricity costs.
In July of 2019, my AC unit died, so now was the time. It took about 6 hours to complete the installation of the furnace and AC unit. Now, as I write this in January 2020, I have promoted this to my family and friends.
The Cocoon system uses 41% less electricity than a standard electric furnace and puts out warmer air-duct temperatures than standard electric furnaces or heat pumps. The duct temperatures are like that of a gas furnace, putting it in competition with gas furnaces, and setting a benchmark that standard electric furnaces could ever hope to achieve.
By utilizing a smart thermostat, we even can monitor our home heating and Air Conditioning through our cell phones.
