Redring Sunstore Selection


Step 1	Firstly determine where the solar collector can be located. South facing is always preferred, with South-East or South-West perfectly acceptable. To facilitate any of these locations; sloping roof, flat-roof and vertical walls can all be used by choosing one from our range of unique mountings. Pitched - For normal sloping roofs with panels mounted one above the other Flat roof / Vertical - Brackets to allow installation on either flat roofs or vertical walls Butterfly - Panels mounted side by side to suit different shaped roofs If no south, south-east or south-west locations are available, a larger system should be selected for east / west facing locations.




Step 2	Next determine the size of system that is required. Size can be calculated from the number of bedrooms, or the number of people, or the existing cylinder size (which should have already been sized for the application). There is no minimum size as any Redring Sunstore will provide free hot water. For maximum effectiveness always select the largest system for any given application. i.e. for a house with two people but four bedrooms select the Sunstore-210 or Sunstore-250. For an existing cylinder of 110 litres for a house with 5 people select the Sunstore-210 Where there is no existing cylinder or the existing cylinder will not be used, always match the cylinder size to the solar system as per the Size Selection Table. When using an east / west facing location on a sloping roof, with an angle of less than 35 degrees, you should use the product selection for south facing locations. Angles greater than 35 degrees should use the east / west product selections.




Step 3	If the current cylinder is in good condition and is currently providing good service and sufficient hot water, it can be converted to use an external heat-exchanger that requires no additional pumps. By using two patented flanges that fit the cylinder wall, the heat exchanger can be fitted quickly and easily to almost all existing cylinder brands; removing the need for a pre-feed cylinder or replacement of the existing cylinder. If you require or would prefer to install a solar-prepared cylinder you should first select the size using points 1 and 2 above and then determine whether you require a vented or un-vented model based on the plumbing configuration of the house or building. All Redring cylinders, both vented and unvented are designed specifically for use with solar hot-water systems and include a high efficiency solar coil for improved heat-transfer. They are supplied with CFC-free high insulation foam, an immersion heater and thermostat as well as the necessary compression fittings. Redring can also supply an automatic blender valve for all systems. The blender will conserve the hot water supply and regulate the temperature of water reaching the taps. Please note that blender valves can reduce flow-rates. Check here to View and Buy online or for further information and to discuss individual requirements, call our sales office on Tel: 01304 215 575
