The CHP unit
CHP is short for Combined Heat and Power. A CHP unit is a cogeneration system that produces heat and electrical power from gas simultaneously. A CHP unit is used for supplying power to buildings and hot water for heating or cooling through high efficient heat and power generation.
How a CHP unit works
Combined heat and power units operate by using energy from natural gas to drive a gas engine. This engine drives the CHP electricity generator. During operation heat from the gas engine is reclaimed and used to supply hot water from the unit.
Yanmar calls a cogeneration unit a CP: a Cogeneration Package. The unit contains an internal combustion engine, generator, inverter, heat exchangers and control system. Does this sound bulky? No way. Yanmar CPs are small, compact and light-weight and have roughly the same footprint as a conventional heating unit. That means you can put them in any space: in the mechanical room, basement, outside on the ground or on the rooftop.
High on energy, low on the environment
When you connect a CP unit to a building to supply power and hot water, you can achieve an extremely efficient energy level. It utilizes up to 87% of the fuel burn versus the average 33% burn rate of conventional, ‘from the grid’ sources. This typically leads to lower energy costs and reduced CO2 emissions compared to remotely generated electricity from the power grid.
