Kwikot has launched a range of Solar Water Heaters for both Direct System and Indirect Systems, as well as a Solar Collector Panel. The Direct System is used in areas where frost does not occur or where the ambient temperature never falls below 5ºC. The potable water in the solar water heater is heated directly by passing through the solar collector panel/s.

The Indirect System is used in areas where frost occurs and where the ambient temperature falls below 5ºC. The system uses a dilution of Propylene Glycol and water as the heat transfer fluid. The potable water and the heat transfer fluid never mix. The heat transfer fluid passes through the double-jacketed tank and the solar collector panel/s, heating the potable water in the solar water heater indirectly.

Both systems can be used as a Split Systems (Pumped and Thermosyphon Circulation Methods) or as a Close Coupled System (Thermosyphon Circulation Method) and also work as a conventional electric water heater.

The Kwiksol Solar Collector Panel measures 1000mm x 2000mm x 80mm, offering excellent absorption efficiency. The 150lt solar water heater requires one solar collector panel and the 200lt and 250lt capacities two solar collector panels. The glass panel aperture area is 2m².

The Kwiksol Solarfit Conversion Kit Direct and Indirect Systems, has been designed to convert a conventional Kwikot electric water heater to a solar water heater system. The kit consists of a new direct or indirect flange assembly for the electric water heater and a complete solar vacuum tube assembly comprising of an aluminium frame and manifold, 16 glass solar vacuum tubes, a solar circulating pump with a photovoltaic solar panel. The indirect system is also supplied with an expansion tank and a 1litre bottle of Kwiksol Propylene Glycol Solar Heat Transfer Fluid. The water heater will still operate as a conventional electric water heater when there is insufficient solar energy to heat the water.
