Business Details

If you are looking for an energy efficient way to heat water in your home or business, whilst saving thousands on your electricity bill, Cosmic Solar Systems in Johannesburg is what you need.

Cosmic Solar Systems have been successfully installing and servicing solar water heating systems for domestic, commerical and industrial use in Johannesburg, since 1981. We also provide general plumbing maintenance and contracting services in the area.

From solar geysers and swimming pool heating systems to solar energy and industrial systems, Cosmic Solar Systems experts will provide a no obligation consultation to help you find the ideal solution for your needs and budget.

Save up to 40% on your electricity bill

With a system that is sized according to your daily hot water needs, you will see a substantial decrease in your electricity consumption immediately after installation. Approximately 60% of your total electricity consumption is consumed by the geyser, so you can expect an overall reduction of about 40%. The system will have paid for itself in about 4 years.

Long life span

You can expect your Cosmic Solar System to last in excess of 20 years, depending on water quality in your area.

Minimal or no maintenance required

Cosmic Solar Systems require minimal or no maintenance. Direct water heating systems should be flushed out occasionally and indirect ones should be inspected and topped up with heat transfer fluid, if necessary.

Aesthetically pleasing to the eye

Your solar geyser can be installed on the inside of the roof with only the solar panels visible. In some cases where a roof has insufficient pitch and span to accommodate an effective thermosyphon, the geyser needs to be located externally, above the panels.
Our domestic indirect solar water heating systems provide loads of hot water and have an electrical back-up to ensure you have water 24/7/365 on overcast and rainy days. Designed to withstand the harshest weather conditions, including freeze protection, Cosmic Solar Systems have excellent corrosion protection, even with the most aggressive water.

To keep water hot for longer, we use a 50mm thick, high-density insulation. Our systems are durable and reliable (requiring minimal maintenance), and suitable for use in many applications – domestic, resorts, lodges, hostels and cottages.

All Cosmic Solar Systems installations are guaranteed for 5 years.
