Hot water storage for space heating via air to water heat pump? Maximum working pressure: Primary circuit 3.0 bar Maximum operating temperature 85°C.
Range of “POWERflow” Indirect and direct unvented storage cylinders consisting of factory fitted single or twin coil circuit with either a primary or solar coil. The secondary circuit is factory fitted with a temperature and pressure relief valve set at 4.5 bar at 90˚C and an expansion relief valve set at 3.5 bar. The product is supplied with a pressure reducing valve set at 2.1 bar, expansion vessel, tundish and an approved check assembly (suitable for backflow protection against Fluid Category 2). Primary circuit max working pressure: 3.5 bar Secondary circuit max working pressure: 3.0 bar Solar Coil max working pressure: 3.5 bar Primary and Secondary circuit maximum operating temperature 75.0°C Solar Coil max operating temperature 80.0°C
Mitsubishi Electric ‘EHPT20Q – VM2EA’ stainless steel unvented primary thermal store cylinder unit. An inline booster heater is also fitted into the primary circuit. The cylinder is fitted with two pressure relief valves set at 3.0 bar. Heat is transferred from the stored primary water to the secondary water circuit via a plate heat exchanger which provides instantaneous hot water. The primary thermal storage cylinder is to be filled by the use of the supplied temporary filling loop assembly, which consistd of a stainless steel braided EPDM lined flexible hose, a lever operated brass spherical valve and a DZR brass double check valve assembly (suitable for backflow protection against Fluid Category 3) that incorporates a lever operated spherical valve. A primary expansion vessel is supplied to accommodate the expansion of the primary water when heated. An automatic air vent is fitted to the top of the thermal store. The product is supplied with a tundish. Maximum working pressure: Primary circuit 2.5 bar, Secondary circuit 10.0 bar. Maximum operating temperature: Primary circuit 72°C, Secondary circuit 70°C.
McDonald Steel Flow ranges of Direct, Indirect, Solar Single, Solar Twin, Slim Direct and Slim Indirect stainless steel insulated unvented hot water storage cylinders with external expansion. The DHW circuit consists of a temperature and pressure relief valve set at 7.0 bar and 90°C, an inlet control group consisting of a pressure reducing valve adjustable between 2.7 and 3.3 bar, an expansion relief valve (SRV) set at 6.0 bar, a strainer and a check valve cartridge, verified by test (suitable for backflow protection against Fluid Category 2) also supplied with a tundish. Maximum supply pressure to the inlet control group 10.0 bar. Maximum working pressures - Primary circuit 6.0 bar, Secondary circuit 5.5 bar. Maximum operating temperature 65˚C.
