Solar Hot Water

How do Solar Hot Water Systems Work

Solar hot water systems use solar collectors (either solar panels or evacuated tubes) which absorb energy from the sun to heat water for your home. The heated water is then stored in an insulated tank for when you need it. The solar collectors are usually located on the roof of your home - they are best positioned facing north.

On cloudy days, or when hot water usage is higher than usual, your hot water system may need a boost. The booster heating unit will come on when the water temperature falls below the thermostat setting and turn off automatically when the water reaches the required temperature. A gas booster produces less greenhouse gas emissions than an electric booster.

There are many types of solar hot water systems (or solar water heaters) available so it’s important to choose one that suits your needs.

If you live in a frost-prone area ask your installer about frost protection for your solar hot water system.

Benefits of Solar Hot Water Systems

Solar systems cost more to buy and install but the extra upfront cost will be recovered over the life of the system through reduced energy bills. Solar systems will recover their costs more quickly in larger households, in warmer parts of the country, or where there is plenty of access to sunlight.

The benefits of solar hot water far outweigh the upfront cost:

  • The difference in cost will be paid back as you'll spend less on heating water.
  • You will reduce the amount of greenhouse gases your home produces.

And of course another major benefit of solar systems is that they use a renewable energy resource.

Why purchase an entire Solar Hot Water Kit?

We have designed our solar hot water heating kits in a way that combines the most appropriate and effective components with one another. You no longer need to do the extensive research needed to figure out exactly which components make up a fully functional solar hot water system as we have done this for you.

Purchasing solar hot water panels and collectors together in one kit with the rest of the required components also brings down the overall cost of the kit itself as you're buying in bulk and shipping and logistics costs are also reduced.

What makes up a fully functional Solar Hot Water kit?

A typical solar hot water heating system is made up of four main components, namely:

  • Solar collector
  • A Geyser or Storage tank
  • A Thermal controller
  • A Circulating pump

Our product line up includes complete solar systems, as well as solar conversions for electric geysers.

Complete solar water heating systems

A complete solar water heating system consists of a solar geyser, connected to one or more solar collectors, either flat plate or evacuated tubes. Indicative pricing of these systems, fully installed and taking into account Eskom rebates where applicable is as follows:

  150L system from R 10 900 incl. installation and rebate  
  200L system from R 13 900 incl. installation and rebate  
  300L system from R 20 400 incl. installation and rebate  

Solar conversions for existing hot water systems

In some cases your existing hot water system can be converted to a solar system by retrofitting the hot water cylinder with one or more solar collectors. Not all hot water systems are suitable for conversion – our engineers will be able to advise you on this option.

Indicative pricing of these systems, fully installed and taking into account Eskom rebates where applicable is as follows:

Residential conversions

  150L conversion from R 8 500 incl. installation and rebate  
  200L conversion from R 9 750 incl. installation and rebate
