WHAT IS COCOON?
Advanced Thermal Mass
Heating Technology
COCOON uses advanced thermal mass technology to store and deliver heat differently than conventional heating systems.
Instead of constantly cycling on and off to maintain temperature, COCOON manages and releases stored thermal energy to help create more stable comfort, lower energy waste, increased air quality, and improved heating performance.
The COCOON systems support a smarter and more resilient approach to enhance existing HVAC solutions with ease of integration in my mind.
COCOON HVAC solutions start around $1,500 depending on the size of your space.




Redefining Heating Efficiency
The COCOON Furnace is 3rd Party Verified to Use up to 41% less energy!
The following chart shows the annual expected operation expense for different types of furnaces. It is based on a 2000 sqft home, and uses $1 / therm as a basis for natural gas. Fluctuation in gas prices shown through growth on the bars.


Why COCOON's Smarter Heating Efficiency Matters to You?
$AVING$
Heating efficiency impacts more than just energy usage - it directly affects utility bills, comfort consistency, and long-term operating costs.
COCOON Thermal Mass Technology is designed to reduce unnecessary energy waste commonly created by traditional heating systems that constantly cycle on and off.
By storing and managing thermal energy more effectively, COCOON helps deliver more stable comfort while supporting lower heating costs, reduced utility dependence, and up to 41% greater efficiency than traditional electric furnaces.
The technology breakthroughs behind COCOON also allow systems to operate with battery backups or off-grid energy solutions, and Hybrid Power Configurations.

WHAT OUR CUSTOMERS ARE SAYING
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 inside....Read More

Before the COCOON System, I had a 1960’s era, a very inefficient gas furnace to heat my home. 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. Read More..
