A 30 Year old Solahart system in Tahiti secured for cyclones
Cold water is pumped to base of collectors. The solar control unit receives constant temperature information from a hot sensor located in the hot return line of the collector and a cold sensor located at the storage tank. When a temperature differential of greater than 8°C is encountered the circulating pump is activated and cold water is pumped from the bottom of the storage tank to the base of the collectors. As the water is heated it passes to the top of the collectors where it is returned to storage heater This process continues until the temperature differential falls to less than 4°C. Solahart Streamline How the Streamline Works
Two systems available 340lt & 430lt Boost Capacity o 340lt – 200lt with 4.8kw element o 430lt – 285lt with 4.8kw element Both units have a recovery of 103lt per hour over 40 °C rise. Booster element can be connected to continuous or off-peak power. Warranty Performance Solahart Streamline Electric LabourParts Tank5 years3 years1 year Collectors5 years1 year
