Converting a standard gen-set to a CHP/system is easy. The by-product of any engine powered generator is heat. Under traditional operating conditions that heat is wasted, escaping to the atmosphere and helping warm the planet. However, by simply adding a heat exchanger to the exhaust gas side of the genset, most of that waste heat is captured and used to heat hot water for Space heating, washing , personal hygiene and where there is a requirement for industrial process water. No additional fuel is used, so the end user is effectively getting their hot water for free.
