Understanding the different types of solar geysers<\/strong> is essential before installation: the right choice impacts performance, compliance, energy savings, lifespan, and maintenance costs.<\/p>\n South African building regulations and industry standards (referenced below) influence design, installation, and certification. We explain each type technically and practically<\/p>\n A solar geyser<\/strong> is a solar-assisted hot water system that uses solar energy to heat water, reducing or eliminating reliance on electrical resistance heating.

\nSolar Geysers Defined<\/h2>\n
\n
\nClassification of Solar Geyser Systems<\/h2>\n
1. Passive Solar Geysers<\/h3>\n
a. Thermosiphon Systems<\/h4>\n
Solar collectors are below the storage tank, usually roof-mounted. Heated water naturally rises into the tank without pumping.<\/p>\n\n
\n
Installation must comply with SANS 10106<\/strong> for plumbing and safety. SANS 10400-XA requires non-electric heating to provide at least 50 % of annual hot water energy<\/strong>. Book Juspropa Installers Now<\/span><\/a><\/p>\n
\n2. Active Solar Geysers<\/h3>\n
a. Pump-Circulated Systems<\/h4>\n
A small, solar-specific pump moves water or heat transfer fluid between the collector and insulated storage vessel.<\/p>\n\n
\n
All components (pump, controller, valves) must meet acceptable standards and be installed by a technician aware of SANS 10106<\/strong> and associated requirements. We use the Geyserwise 12V or 220V Circulation pump. Get a Geyserwise system now<\/span><\/a><\/p>\n
\nMajor Solar Geyser Types by Construction and Use<\/h2>\n
A. Close-Coupled Solar Geyser<\/strong><\/h3>\n
The collector and storage tank are mounted together on the roof.<\/p>\n\n
\n
\nB. Split Solar Geyser System<\/strong><\/h3>\n
Collector panels are roof-mounted while the storage tank is placed separately (typically in roof space).<\/p>\n
