‘POD’ range of indirect and direct heat interface units providing space heating and instantaneous hot water. The heat transfer is generated via plate heat exchangers. The domestic hot water (DHW) circuit incorporates an adjustable temperature mixing valve. The indirect models incorporate an expansion vessel (on the CW inlet of the DHW circuit) and a pressure relief valve set at 3.0 bar (on the space heating circuit). The indirect models only are supplied with a temporary filling loop, which comprises of a stainless steel braided EPDM lined flexible hose assembly and a lever operated spherical valve for connection to the primary circuit. The angled cold water inlet incorporates an isolation valve and a branch to connect to the filling loop, which includes a double check valve assembly (verified by test, suitable for backflow protection against Fluid Category 3). Maximum working pressure for indirect units: Primary circuit: 16.0 bar. Space heating: 2.5 bar. Secondary circuit (DHW): 10.0 bar. Maximum working pressure for direct units: Primary circuit: 10.0 bar. Space heating: 10.0 bar. Secondary circuit (DHW): 10.0 bar. Maximum operating temperature for domestic hot water 65°C. Maximum operating temperature for central heating and primary circuit 85°C.
Range of stainless-steel plate heat exchangers. Maximum operating pressures - primary circuit: 3.0 bar, secondary circuit (DHW): 10.0.bar. Maximum working temperature 80°C.
Under counter electric instantaneous water heater with a stainless steel tank. The flow is controlled via a solenoid valve. The product is supplied with a 3 way isolation valve (15mm compression x 15mm compression x ¾” BSP (M)), as well as a filter head and filter cartridge for installation prior to the under counter unit. LLDPE tubing and pushfit connections are provided for connecting between these items. The filter head inlet incorporates an approved check valve cartridge, however, the complete product has not been fully tested to demonstrate it provides backflow protection. The inlet to the under counter unit incorporates a combined silicone washer and stainless steel strainer and an approved check valve cartridge, however, the complete product has not been fully tested to demonstrate it provides backflow protection. Maximum working pressure 5.5 bar. Maximum operating temperature 98˚C. Cold water supply only.
Range of wall mounted, gas-fired, condensing combination boilers providing domestic hot water via a plate heat exchanger. The pressurised central heating system incorporates an expansion vessel and a pressure relief valve set at 3.0 bar. The inlets to the domestic hot water and primary circuits each have a screwdriver operated angled spherical valve. Both include a ½” BSP (M) connection for a filling link. The Greenstar CDi models only are supplied with an integral charging link (CAB device) verified by test (suitable for backflow protection against Fluid Category 3). Maximum working pressure of the primary circuit is 2.5 bar. Maximum working pressure of the secondary circuit is 10.0 bar. Maximum operating temperature of primary circuit is 82°C. Maximum operating temperature of secondary circuit is 60°C.
Range of electric combination boilers providing heating and instantaneous hot water. The heating system incorporates an expansion vessel and pressure relief valve (set at 3.0 bar). The DHW inlet and outlet incorporate spherical servicing valves. Fittited with a CAB device keyless filling link, verifired by test, suitable for category 3 backlfow protection. Maximum working pressure on central heating circuit 2.5 bar & Domestic Hot Water 10bar. Maximum operating temperature 80°C
