Solar equipment manufacturer nrg technologies offers thermal solar systems in low pressure and high pressure models.
High pressure solar geyser installation diagram.
Low pressure solar geysers are typically used in rural areas and farms where municipal water supply is not available.
Most new geyser installations are typically high pressure 400 600kpa system by far the most common type in south africa.
Collector captures solar energy as heat heat transferred to water either directly or via a transfer fluid hot water is stored in a hot water cylinder geyser systems.
Components of a hot water heating system.
The low pressure gravity feed complete system consists of a vacuum glass tube collector an insulated storage tank and optional stand parts make up tank the evacuated glass tubes are filled with water and exposed to sun thus heating up the water in the glass tubes.
Introduction all novasun solar hot water systems are high quality thermal solar systems using advanced technology to convert light into heat.
An average person uses 50 litres of hot water in a 24 hour.
This installation manual must be read and understood before undertaking the installation of a novasun solar hot water system.

Collector panel which must face north at an angle of around 40.
What size low pressure geyser do you need.
This is because the materials used for high pressure systems must be of high quality and strength in order to withstand the pressures created by the system.
Solar geyser which is not the same as a normal high pressure geyser although you may be able to modify your existing geyser to work with the solar panel you will have to check with a professional in the industry before attempting this though.
Low pressure systems 100kpa are significantly different but are fairly uncommon now.
