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 RINNAI continuous flow water heaters with stainless steel plate heat exchangers providing heating and instantaneous hot water .The hot water is generated via a plate heat exchanger. Also supplied is a drain valve and a flow sensing device. Maximum working pressure - 10 bar Maximum working pressure - 85˚C
Shower waste water heat recovery unit, consisting of a PVC-U waste pipe with an internal copper tube which provides a double wall separation between the waste water and cold mains supply. Maximum working pressure 10.0 bar. Maximum operating temperature 30°C.
