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 wall mounted combination boilers providing domestic hot water via a plate heat exchanger and pressurised central heating system, incorporating a pressure relief valve set at 3.0 bar and expansion vessel on the primary circuit. The inlet of the replenishing valve between the primary and secondary circuits incorporate a plastic strainer. Maximum working pressure 2.5 bar (primary) and 6.0 bar (secondary). Maximum operating temperature 85˚C.
Range of water meter manifolds with plastic bodies. The inlets incorporate a spherical valve and a non-return valve (not suitable for back flow protection). Model MD1010101BM is for use with Irish Heavy gauge pipe manufactured to 15134/1977. All other models are for use with blue MDPE pipe manufactured to EN12201. Maximum working pressure 12.5 bar. Cold water use only.
Range of water meter manifolds with a plastic body and a spherical valve at the inlet.
