CHP stands for Combined Heating and Power. These devices typically burn gas to simultaneously produce both hot water (similar to a boiler) and electricity. CHP devices are rarely a benefit unless you can utilise both the heat and electricity that is generated. Typically, your building will always make use of the electricity but finding use for the heat can be more difficult, particularly during the summer. For this reason, CHP units should be sized around your buildings ‘base’ heat demand. If sized and installed correctly, CHP devices will deliver both cost and carbon dioxide emission savings.
