CHP technology is the use of a heat engine to simultaneously generate electricity and useful heat. In standard generators for the production of electricity, some energy must be discarded as waste heat, but in cogeneration this thermal energy is used through the use of a number of heat exchangers. This system increases the overall energy efficiency of the generator from about 35% to more than 85%.
A Micro-CHP has been developed by SMARTer homes, designed to be small enough to make it an efficient source of energy for household use, increasing as its compliment, the attractiveness of using other renewable energy devices such as photovoltaic panels, with which it can communicate wirelessly.
The key of SMART Micro-CHP concept, is the fact that it treats the grid as an option and not as a permanent energy supply in meeting the domestic energy needs, while also acting as a backup generator
