Electronically controlled heat interface units (HIU) with twin stainless-steel plate heat exchangers providing space heating and instantaneous hot water. The cold inlet supply to the plate heat exchanger incorporates an isolation valve and a water hammer arrestor. The space heating circuit incorporates an expansion vessel and a pressure relief valve (set at 3.0 bar). The product is supplied with a filling loop assembly consisting of an elbow shaped copper pipe, isolation valve and double check valve assembly (suitable for backflow protection against fluid category 3) which incorporates an isolation valve. The cold mains inlet and the domestic hot water outlet each incorporate a brass bodied spherical valve with a butterfly handle. Maximum working pressures and operating temperatures: Primary: 16.0 bar and 90˚C. Domestic hot water (DHW): 10 bar and 65˚C. Secondary (space heating): 2.5 bar and 85˚C.
Range of cold-water inlet control groups with DZR brass bodies consisting of an in-line, adjustable pressure reducing valve (PRV) (adjustable in the range of 0.8 bar - 6.0 bar, but factory pre-set at 3.0 or 3.5 bar - see model), strainer and a DZR brass bodied pressure relief valve (SRV) (set at 4.75 bar or 6.0 bar - see model). Products also incorporate an approved single check valve cartridge, verified by test (suitable for backflow protection against Fluid Category 2). Maximum supply pressure 16.0 bar. Maximum operating temperature 80°C.
