[EnergyPlus_Support] Re: CHP for central heating



I'm doing the same simulation but for a green house. The MicroCHP generator that i use is a ECPower with 13kW Electrical Output and 29kW Thermal Output. He never has been able to provide all the hot water but i usa a small air to air heat pump to complete the heating system. The heat pump never demand all the electric energy produced by de MicroCHP. So i spent 50% less in natural gas than the boiler with this system.
