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 vertical vented cased copper cylinders with indirect coils. The secondary circuit incorporates a thermostatic mixing valve. The inlet consists of a ball valve with strainer, inline non verifiable single check valve and mini shock arrestor. Cylinder are supplied with a factory fitted immersion heater. Maximum working pressure - secondary 6.0 bar, primary 2.2 bar. Maximum operating temperature - secondary is 60°C, primary 85°C
