Range of wall hung, gas fired, combination boilers providing domestic hot water via a plate heat exchanger. The primary circuit incorporates an integral expansion vessel and a pressure relief valve set at 3.0 bar. The product is supplied with a rigid pipe filling loop, followed by a separate isolation valve. The filling loop pipe attaches to the cold water inlet valve which incorporates a double check valve assembly (verified by test, suitable for backflow protection against Fluid Category 3) on the branch to the filling loop. The primary circuit includes an isolation valve on the flow and return and is also supplied with two loose 22mm compression isolation valves and a filter. Maximum working pressure of the primary circuit is 2.5 bar and the maximum supply pressure to the secondary circuit is 10.0 bar. Max operating temperature 65°C.
