Combined heat and power (CHP) uses heat that would otherwise be wasted in the production of electricity in a variety of productive ways. It can be micro-cogeneration systems that produce both electricity and heat for one building, up to larger devices that provide district heating for entire regions at the same time. Thanks to this, the combined production of heat and electricity is one of the most efficient methods of energy use. In fact, up to 90% of the energy is often recovered. The heat exchangers used in the CHP system are a decisive factor in achieving maximum efficiency. The company Energy&Bau s. is here for you with this issue. r. about.
