What is Residential CHP (Micro-CHP)?Small Scale Cogeneration

( )

Fuel Input = Heat + Electricity

Micro-CHP: Replaces existing furnace/boiler

Sized for residential use

Retrofit ready

Uses existing installers

Makes electricity at home

Make Electricity While Heating Your Home!Efficiencies >90%!!
