vTherm°e (Electronic) Installation Commissioning and Maintenance Manual

The new space saving vTherme Heat Interface Unit (HIU) has been designed to minimise heat losses and improve the efficiency of your district heating scheme. The new product range is available in a variety of outputs providing instantaneous Domestic Hot Water (DHW) and Heating (HTG) for radiators or underfloor heating (UFH) systems in homes. The HIU provides complete hydraulic separation between the primary circuit and the secondary DHW and HTG installations. The HIU is electronically controlled to give precise control of temperature which improves efficiency and lowers return temperature. Instantaneous hot water and heating is produced via a plate heat exchangers and Pressure Independent Control Valves (PICV).
