Solar Geysers, or Solar Water Heaters (SWH) are sustainable, environmentally-friendly, and save you money every month.

Without the use of backup elements, an electric geyser will recover and warm the water quicker. The electric geyser’s 4kW element switches on as soon a warm water tap is switched on. Your solar geyser’s 2kW element is switched OFF at certain times as required by Eskom. Therefore, at certain times (depending on your water use) your water will be colder than from the electric geyser.

Cost saving on the other hand is clearly measurable. Please see the “Solar Geyser Savings Chart”

Will I always have hot water?

You can always have hot water! This is achieved by setting the correct times your backup elements will work.

What about backup elements?

These are electric (or battery powered) backup elements. After a short time, you will realise when you use the most hot water. This will put some strain on the amount of hot water available at other times. When you require hot water and do not have it at that time… set your backups to switch on just before these times.

Do Solar Geysers require maintenance?

Yes. Simple maintenance can be done yourself, but rather call a JTS Professional to check all the parts and do a thorough check at the same time.

6 Top Tips to Save on Electricity

By following some basic adjustments to water use, you will be able to maximise your savings.

Allow the Sun

Allow the sun as much time as possible to heat up the water.

Morning Water

If you have used the bulk of your water during the day, you may need to use your electricity backups. These will heat the water for evening or morning use.

Minimise Backups

Minimise the use (and amount of) of electricity backups used to heat your water.

Backup elements

By reducing the amount of backup elements you risk not having enough hot water after hours. This maximises energy savings.

Evening Water

Use up most of your hot water a night. This way the sun has heated the bulk of your water.


If more capacity is required for hot water, you may decice to increase the geyser size. If this is not sufficient (or suitable), more solar panels and geysers can then be installed.

Common Solar Geyser Problems

Most solar geyser products are hail resistant, freeze resistant and resistant to overheating issues. Usually solar geysers, if properly installed, are maintenance free. But, this doesn’t mean a solar geyser can’t develop problems.

The most common problems solar geyser systems develop are:

Not enough hot water - geyser not heating up

A solar geyser which does not provide enough water to your home can be frustrating especially if it’s newly installed. The most common reason for a solar geyser not producing enough hot water is due to the solar panels being incorrectly installed.

Our licensed plumbers can conduct a solar geyser inspection and determine the hot water issue quickly and make the correct adjustments or repairs for your solar geyser.

Solar panels not working to full capacity

A solar geyser’s solar panels should always be working at their full capacity for the best solar water heating results. After years, solar panels can deteriorate and lose their solar effectiveness. A solar panel should not operate under 80% of solar heating capacity. Our plumbers can inspect your solar panels and do any solar panel replacement or repair as needed for your solar panels to work at their full capacity.

Incorrectly installed solar geyser

Incorrectly installed solar geyser systems can cause many issues for your solar system in the long-run. Always ensure to hire a licensed solar geyser installer such as JTS Plumbing for all your solar geyser installation requirements. We also advise to never install or remove a solar geyser yourself. Solar geyser DIY may damage the solar geyser or solar panels in the process beyond repairs. An incorrectly installed solar geyser may not produce enough hot water and also, the solar panels can get loose on the roof. Call our licensed solar geyser emergency plumbers to ensure your solar geyser is correctly installed and is compliant to CoC certification of your home.

Faulty conductor rod

Many brands of solar geyser products make use of a conductor rod to heat the cold water. Corrosion and sediment inside the water storage tank may lead to a faulty conductor rod. The best way to determine this, is to hire our plumbers and electricians for an inspection who can also replace your faulty conductor rod effectively.

Solar geyser leaking water

Solar geysers leaking water may be due to incorrectly installed solar geysers or other damages to the solar geyser. Also, due to water pressure inside the solar geyser system, the pressure-relieve valve may begin to leak. Also pipes connected to the solar geyser can start leaking for the same reason. But no matter what caused the water leaks, our plumbers are always ready to assist you by finding any solar geyser water leak and conduct professional repairs for you.

Faulty solar geyser circulation pump

JTS Plumbing’s plumbers will inspect all components of your solar geyser to determine any issue that your solar geyser might have. Many times, a solar geyser’s circulation pump may be faulty due to blockages or improper circulation pump installations. Luckily, our plumbers are skilled and experienced to conduct circulation pump repairs if possible or replace your solar geyser’s circulation pump.
