Range of domestic stainless steel or coated carbon steel indirect unvented hot water storage cylinders and buffer tanks, incorporating a stainless-steel coil for connection to a heat pump circuit. The secondary circuit is factory fitted with a temperature and pressure relief valve (7.0 Bar @90°C) and an immersion heater. Maximum working pressures: Water storage tanks (ECO-ZR200S and EG-200CAIO): 5.5 bar. Buffer tank (ECO-ZR60 and ECO-ZR60S): 7.0 bar. Maximum operating temperature 70°C. The ECO-ZR60 and ECO-ZR60S models are to be used in a primary circuit only.
Excelsior Range of Direct and indirect unvented storage cylinders. 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: 5.5 Bar (All Circuits) Maximum operating temperature 90.0°C
Range of unvented heat pump storage cylinders which consist of an air-source heat pump sitting on top of the tank with either no internal coil (model numbers ending without S) or a factory fitted single internal coil (model numbers ending with S). The secondary circuit is factory fitted with a temperature and pressure relief valve set at 7.0 bar @ 90˚C and an stainless steel immersion heater and titanium alloy anode. The product is not supplied with an inlet control group (safety kit). Maximum operating temperature 70°C. Maximum working pressure (primary & secondary circuit) 5.5 bar.
Rinnai range of Direct and indirect unvented storage cylinders. 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: 5.5 Bar (All Circuits) Maximum operating temperature 90.0°C
Range of gas fired, unvented hot water storage heaters. The DHW circuit consists of a temperature and pressure relief valve (set at 7.0Bar). Maximum working pressure: 6.5 Bar. Maximum operating temperature: 85°C.
Range of single or double tank water heaters, incorporating enamel coated carbon steel tank. The secondary circuit is factory fitted with a temperature and pressure relief valve (10.0 Bar). Maximum working pressure 8 bar. Maximum operating temperature 75 °C.
Range of “Tempest” 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 7.0 bar@90˚C. The product is supplied with an inlet control group (safety kit) consisting of a pressure reducing valve adjustable between 2.7 and 3.3 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 supply pressure to the inlet control group 10.0 bar. Maximum working pressures: Secondary circuit 3.0 bar, Primary Circuit 5.5 bar & Solar circuit 5.5 bar. Maximum operating temperature 70°C.
