Accelerating the Decarbonization of Buildings 

Heat, Power and Backup Power – All in One System

Enviro Power’s innovative SmartWatt boiler, the world’s first boiler with a mini power plant inside, is a major step forward in the fast-changing energy world. Designed to convert heat lost in traditional boilers into useful electricity, the revolutionary boiler is designed as a drop-in replacement for conventional heat and hot water system boilers.

Our mission is to decarbonize millions of buildings and help property owners move toward energy independence by replacing aging heating equipment with the SmartWatt Boiler technology. Already in use at apartment buildings, college dorms and other commercial buildings, the boiler is manufactured in the U.S. and is easy-to-install and maintain at similar costs of traditional heating systems.

Generating clean, near-zero cost onsite electricity at nearly 98 percent (HHV) heating efficiency, the SmartWatt Boiler ls one of most efficient heating solutions available thanks to a patented dual-condensing combustion chamber.


Helping property owners reduce their energy costs, the SmartWatt Boiler utilizes a closed loop, radial, micro-steam turbine incorporated in a light-commercial combustion chamber to generate up to 6 kW of free electricity while heat is being produced.
