This roof mounted, close-coupled, solar hot water system can be easily installed on tile, steel clad or flat roofs. There are no complicated pumps or controllers to worry about as the circulation of the hot water is automatically achieved using the natural thermosiphon principle.
The system is backed up by a thermostatically controlled electrical element.
1 x 150L Tank
1 x 18 Evacuated Tube Collector
1 x Stand
1 x 1kW Heating Element
1 x 7/11" Standard Thermostat
* The simple compact design leaves no space for extra components which can leak, freeze, burst, lose heat, or simply stop working.
* The heat pipes fit directly into the tank. There is only a sleeve inside the tank, so heat loss is minimal.
* Because the whole system is on the roof, it is easier to install, which also cuts costs. It obviously cannot leak through a ceiling
* This is a high pressure system. It can be used for city pressure, although it has been tested at much higher pressures.
* Problems with freezing can be expected only at MINUS 35o Celsius.
* All high pressure systems use a 1.2mm stainless steel tank.
* There is an optional electronic control panel, which controls the electric backup element. This panel controls 1, 1.5 or 2 kW elements, and can even be plugged into a normal three point plug, as it draws less Watts than normal electric geysers.
* A frequently asked question is about hail: All our systems use 2mm tubes, designed to withstand 38mm diameter hail. They are surprisingly cheap to replace.
