How Cocoon - the most efficient furnace

While Cocoon Furnaces use electric, they are not electric furnaces.


Traditional electric furnaces can be compared to a toaster with a blower. They usually have wired heating elements that heat up, and a fan that blows that heat around your home. They heat and blow until the thermostat achieves the temperature, then they turn off, wait for the thermostat to decrease, then start the whole process over again.


They run inefficiently, constantly in an “on” and “off” process, which makes them expensive to operate. They are also known to create a "dry heat" and cause cold spots around your home.

Cocoon is not a gas furnace, so it doesn’t rely on fossil fuels and the fluctuating prices associated with the commodity. This means it also doesn’t present the dangers of an open flame, flammable gas, or carbon monoxide that natural gas and propane furnaces introduce to a home or business.


Gas furnaces typically use a flame to heat an exchanger and a blower pushes the warm air off the exchanger throughout your home. It does this until the thermostat reaches temperature. Then it stops until the thermostat tells it to start again - when the flame fires back up and "reheats" the exchanger. Again creating an "on" and "off" situation.  


The Cocoon Thermal Mass Furnace uses long wave infrared heat to warm a thermal mass – think of it like a giant stone. This mass “holds” the heat in a more consistent fashion, and our blower distributes that heat throughout your home. The thermal mass’ ability to hold the heat increases efficiency by reducing the “on” and “off” cycles of the energy used to heat it.


The blower gently pushes air across the heated mass until the thermostat reaches temperature. Then it stops blowing and heating the mass. But the mass stays warm due to its inherent nature. When the thermostat communicates a decrease in temperature, the blower resumes blowing across the mass –it may or may not need to be reheated, but it never requires a complete heat up like a traditional electric furnace heating element. This reduces the “on” and “off” cycles, reduces energy consumption, and creates a more constant, comfortable heat.


The mass holds any temperature, so in the summer it will increase the efficiency of your air conditioning as well by holding and redistributing the cooler temperatures.

Cocoon's technology and modularity waste less energy than any other furnace – giving Cocoon owners truly affordable energy efficiency.


The amazing technology breakthroughs also allow it to be ran off grid with battery backups!

Maintaining comfort levels is the key to energy efficiency in any HVAC system. The Cocoon Thermal Mass Furnace with its infrared heat is the king of maintaining comfort levels. From the thermal mass to the computerized brain offering customizable efficiency – you get complete control over your comfort and efficiency.


Cocoon Furnaces approach the efficiency of a geothermal unit without the large investment and retrofitting.

While geothermal systems are the most efficient systems out there for those seeking true efficiency, they present what are “unmanageable” hurdles for the general public.


They require a significant monetary investment – between $30,000 and $150,000 depending on the size of your home. They also require significant retrofitting and digging into your property. Many homes just can’t accommodate those required retrofits.

Coccon Green Energy - Path to Energy Ind

Cocoon is modular in design and fits anywhere. Even places traditional HVAC systems and geothermal systems cannot.


The Cocoon Thermal Mass Furnace starts at $2300.

That’s affordable energy efficiency for the rest of us.

Cocoon reduces your reliance on fossil fuels, runs more efficiently, and provides the same level of comfort as gas or propane. It also performs up to 41% more efficiently than a traditional electric furnace. It currently retails for just about the same price as any high efficiency gas or electric furnace and HVAC system.
