Optimum Energy Solutions – overview of a live heat pump demo

Optimum Energy Solutions has a demo / exhibition trailer fitted with a working Air Source Heat Pump, system controller and Fan Coils Units. It also has a dummy Ground Source Heat Pump. The system also has an internet connection so remote operation and monitoring can also be shown. Local power is required on site - the system has been designed to run from a standard single phase 230 volt 13 amp domestic supply outlet.

  • Heating systems: the most important aspect of ANY system
