HL 352

Domestic Water Heating System

Technical Description

The unit features viewing windows built into the sides of the boiler which enable the flame to be observed. The immediate results of different burner settings are directly visible. The unit contains a heatable domestic water tank as a second load. The system is equipped with all stipulated safety devices. All water circuit temperatures and flow rates together with the oil pressure and combustion chamber temperature are measured. An integrated hot water circuit with a plate heat exchanger simulates a central heating circuit. All measured data is transmitted to a PC and displayed. The system is supplied with an oil burner and oil tank as standard. Gas burners are available on request.
