HOW THE COCOON THERMAL
MASS FURNACE WORKS
TRADATIONAL ELECTRIC FURNACE OVERVIEW
Traditional electric furnaces work similarly to a toaster with a blower - electric heating elements generate heat while a fan distributes that heat throughout the space.
To maintain temperature, these systems constantly cycle on and off, repeatedly reheating the elements each time the thermostat calls for heat. This process can create uneven temperatures, overly dry air, and higher energy demand over time.
While traditional electric furnaces remain common, they were never designed around thermal energy storage or modern energy flexibility.
GAS FURNACE OVERVIEW
Traditional gas furnaces create heat through combustion and move that heat throughout the home using forced air. Like electric furnaces, gas systems cycle on and off throughout operation to maintain temperature.
While gas heating remains popular, these systems rely on combustible fuel sources and are affected by fuel price fluctuations, combustion emissions, and increased maintenance.
COCOON Furnaces are designed to provide stable indoor comfort without relying on combustion-based heating.
COCOON THERMAL MASS FURNACE OVERVIEW
The COCOON Thermal Mass Furnace uses medium to long-wave infrared energy to heat a specially engineered thermal mass that stores and delivers lasting heat over time. Think of it like a giant stone warmed by the sun - even after the sun goes down, the stone continues releasing stored warmth. COCOON works similarly by storing thermal energy and redistributing it as needed to help maintain more stable indoor comfort.
Unlike traditional furnaces that constantly cycle heating elements or burners on and off, COCOON’s thermal mass technology helps reduce the cycling, unnecessary energy waste while delivering consistent, balanced heat.
The thermal mass also retains cooler temperatures during warmer months, helping support improved cooling performance. COCOON’s modular technology can also operate with battery backups, hybrid systems, and off-grid energy solutions for greater energy flexibility.

COCOON’s Thermal Mass Technology and modular design are engineered to reduce and recapture wasted energy while supporting smarter long-term comfort with improved energy management.

HOW COCOON COMPARES TO GEOTHERMAL
Geothermal systems are widely known for delivering efficient, consistent indoor comfort by using stable underground temperatures to help heat and cool a space. While geothermal systems offer strong performance, installation costs, excavation requirements, and retrofit limitations can place them out of reach for many homes and buildings.
COCOON Thermal Mass Technology was designed to deliver stable comfort and lower energy waste through a simpler and more flexible installation approach at a fraction of the cost of geothermal solutions. COCOON’s modular design allows installation flexibility across residential, commercial, and specialty applications where geothermal may not be practical.
WHY CHOOSE COCOON?
The COCOON Thermal Mass Furnace starts at $2300.
​
By combining thermal mass technology with medium to long-wave infrared heating, COCOON helps reduce and recapture wasted energy while delivering balanced, long-lasting comfort. COCOON performs up to 41% more efficiently than traditional electric furnaces and can operate with battery backup, hybrid, and off-grid energy solutions for greater flexibility and energy resilience.
Unlike combustion-based systems, COCOON delivers consistent indoor comfort without relying on gas or propane. With pricing comparable to many high-efficiency gas and electric furnace systems, COCOON makes advanced thermal comfort technology more accessible with improved performance or flexibility.
