HL 108

Domestic Heating Circuit Training Panel

Technical Description

A pump circulates water through four radiators. The temperature of the radiators is set using thermostatic valves. A digital controller keeps the room temperature constant by driving the fourway mixing valve. This valve sets the temperature of the boiler return and the heating feed flow. Cold water connections enable the heat generated to be dissipated. The differential pressure across the pipe system is limited using a relief valve. Temperatures can be read on dial thermometers.
Supplies of hot and cold water are required for operation.
The training panel can be fitted to the HL 100 Universal Stand.
