HOW YOUR WATER HEATER WORKS
The Rheem solar Loline system has its vitreous enamel lined solar storage tank installed at ground or floor level, remotely from the solar collectors. As the sun heats the water in the solar collectors the increase in temperature activates the circulator. The circulator then moves the water from the solar collectors through an insulated copper pipe to the solar storage tank. The circulator switches on whenever the water in the solar collectors is hotter than the water in the tank. Cooler water from the solar storage tank is circulated to the solar collectors to be heated by the sun’s energy. This process continues while solar energy is available and until the water in the solar storage tank reaches a temperature of approximately 75C.
MAINS PRESSURE
The water heater is designed to operate at mains pressure by connecting directly to the mains water supply. If the mains supply pressure in your area exceeds that shown on page 19, a pressure limiting valve must be fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
ELECTRIC BOOSTING
Water stored in the solar storage tank can be heated by an electric booster heating unit. The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy or rainy weather, or during the winter months.
The booster heating unit is controlled by an electric thermostat. The thermostat and its over temperature energy cut out are mounted on the solar storage tank behind the front cover. The water temperature is automatically controlled to the thermostat setting when the booster heating unit is energised.
The Optima models feature a user adjustable thermostat, which allows you to choose the most suitable boost temperature for your hot water needs. It has a minimum temperature setting of 60C and a maximum temperature setting of 75C. The thermostat on the Rheemglas models is tradesperson adjustable. It has a minimum temperature setting of 60C and a maximum temperature setting of 70C. It can only be adjusted by an authorised person. Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
