The technology behind Combined Heat and Power (CHP) is simple: instead of sourcing electricity from the local utility and creating hot water or steam with traditional boilers, a CHP system performs both functions with one machine using low-cost natural gas.
A CHP system burns natural gas and uses the force created by combustion to spin a generator. During combustion, waste heat is captured from the engine and fed into the building to offset hot water creation normally performed by the boilers.
