The report compares the economics of small gas-fired industrial boilers with boilers that generate steam using electricity. Using the total costs of owning and operating each type of boiler as the basis for comparison, the report concludes that, given expected future fuel prices, no significant economic competition is expected from electric boilers.

Combined heat and power (CHP) is the simultaneous cogeneration of electricity and heat. Cogeneration is a highly efficient form of energy conversion and using gas engines it can achieve primary energy savings of approximately 40% compared to the separate purchase of electricity from the electricity grid and gas for use in a boiler.. If the fuel for the gas engine is renewable …
