The trainer contains two independent heating circuits that are equipped with a three-way mixing valve and a four-way mixing valve.
The heat provided by an electric boiler can be dissipated via four different radiators. To investigate the full load behaviour of the boiler over an extended period, a plate heat exchanger is fitted in the domestic water circuit. The system has a closed water circuit with expansion vessel. Relevant temperatures and pressures are indicated on easy-to-read instruments.
The system is controlled using a state-of-the-art digital controller.
