Back To Directory SectionsCenterstore 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.
Range of CENTERSTORE AIR bubble top indirect and direct single coil unvented storage cylinders. The secondary circuit is factory fitted with a temperature and pressure relief valve set at 10.0 bar@90˚C. A safety kit (manifold) consisting of a single check valve assembly, verified by test (suitable for backflow prevention against fluid category 2), strainer, an expansion relief valve set at 8.0 bar and a pressure reducing valve set at 3.0 bar and a tundish is also provided. Alternative inlet control group and temperature and pressure relief valve added March 2023. Maximum working pressure: Secondary circuit: 7.5 bar. Primary circuit: 6.0 bar. Maximum operating temperature 65°C.
Range of indirect unvented indoor heat pump storage cylinders which consist of a heat pump which sits on top of the tank and heats the hot water via refrigeration pipes which then heats the cylinder by being externally mounted around the cylinder. The secondary circuit is factory fitted with a temperature and pressure relief valve set at 7.0 bar @ 90˚C. The product is supplied with an inlet control group (safety kit) consisting of a pressure reducing valve pre-set at 3.0 bar, strainer, an expansion relief valve set at 6.0 bar and a check valve cartridge (verified by test - suitable for backflow protection against Fluid Category 2). A tundish and expansion vessel are also provided. Maximum working pressure 6.0 Bar (Secondary) Maximum operating temperature 55.0°C
Range of Direct & Indirect stainless steel insulated unvented hot water storage cylinders with internal expansion. The secondary circuit consists of a temperature and pressure relief valve set at 10.0 bar and 90°C and an alternative temperature and pressure relief valve also set at 10.0 bar and 90°C , an inlet control group consisting of a pressure reducing valve pre-set at 3.0 bar, an expansion relief valve set at 8.0 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 working pressure - Primary circuit: 6.0 bar & Secondary circuit: 7.5 bar Maximum operating temperature 85.0°C
Range of stainless steel indirect (single or twin coil), direct and heat pump unvented hot water storage cylinders. The heat pump models also incorporate a plate heat exchanger and a circulation pump. The secondary circuit is supplied with a temperature and pressure relief valve set at 7.0 bar@90.0˚C. The products are supplied with an inlet control group consisting of an adjustable pressure reducing valve, adjustable in the range of 0.8 bar - 6.0 bar, but factory pre-set at 3.0 bar, a strainer, am expansion relief valve set at 6.0 bar and an approved single check valve cartridge, verified by test (suitable for backflow protection against Fluid Category 2). The products are also supplied with an immersion heater, an expansion vessel (12, 19 or 24 litres depending on model) and a tundish. Maximum supply pressure to the inlet control group: 16.0 bar. Maximum working pressure: Secondary circuit: 5.5 Bar. Primary Circuit: 6.0 Bar (All models except for the Direct - DI prefix models). Maximum operating temperature 75°C.
