Solar Geyser Retrofit Packages

  • Systems are “Retrofit” where own geyser is retained and converted to solar.
  • High pressure system (suitable for showering etc. unlike low pressure systems) where for example a 30 EVT system produces 9.6kW and 374L of hot water per 24 hours at 40C.
  • Built in system controller ensures constant flow of hot water (most systems do not have).
  • Includes anti-overheating system designed not to overheat even in extreme summer temperatures.
  • Lowest price per kWh for solar generated hot water and highest quality system available in South Africa.
  • The only high pressure systems that can meet 100% of electricity replacement without overheating.
  • The only system which has overcome the problem of overheating in stagnation, when no hot water is being used from the tanks.
  • System is ‘plug & play’ enabling flexibility in meeting the different demands of orientation and inclination.
  • System is almost zero maintenance, incorporating anti reverse siphoning technology.
  • The system is the cheapest when compared on a ‘like for like basis’ on performance per Rand invested.
  • All our systems are manufactured in South Africa.
  • System carries a 10 year manufacturer’s guarantee.
Do I need to install my own solar geyser conversion?

You don’t need to! All our packages include standard installation so you don’t have to worry about a thing.

Thank you, AquaTherma Investments, Cameron and his team - you are the best. Thank you for helping us save money on our utility bill. The retrofit geyser system is the best in getting a "Hybrid" system going.

In January of this year I had a retrofit solar geyser installed at my residence by Aqua Therma and I couldn't be happier with the results. From start to finish, the process was smooth and efficient. The installation team at Aqua Therma was highly professional, knowledgeable, and courteous throughout the entire installation process. Not only did Cameron and team provide excellent customer service, but the quality of the installation itself was beyond any of my own expectations. The solar geyser is not only providing reliable and efficient hot water for me and my family, I've already noticed a significant decrease in my electricity usage. I've also noticed a reduction in my monthly electricity bill. I would highly recommend Aqua Therma for anyone considering a solar geyser installation. Their expertise, attention to detail, and commitment to customer satisfaction make them stand out in the industry. Thank you to the Cameron and the team.

I highly recommend AQUATHERMA Investments due to their great and professional experience with the installation of solar geyser systems. Their work seem to be excellent as observed from the beginning when I had a good and informative interaction with Mr Cameron (Manager) on how the solar system works until he could dispatch his professional team of specialists to site for implementation and execution of the project as required by myself as a client. Mr Cameron also offered me a good return on investment quote which I ultimately had to accept for the installation of 42 EVT solar tubes with a smart remote monitoring system called aquatrac system. To be precise, their meticulous work performance was very impressive until the project got completed. I saw it fit to put it on record that this system works perfectly fine as supported by their after-sales service which they still provide in the usage of the solar geyser remote monitoring system-dashboard system. Highly recommended and you cannot go wrong with their service. Happy Client, Ernest Lekalakala

I installed a 200 litre solar geyser with 20 EVT tubes in August 2022. For the whole year i was struggling to get Kwikot to resolve my water heating challenges without success. Even on a good sunny day in summer, i would get nothing more that 15 degrees increase in water temperature. In August 2023, i contacted Aqua Therma with my problem and they assured me that they have a solution for me. They installed additional 18EVT tubes to my existing installation, and i was assured that i will no longer struggle with hot water. My experience to date, my geyser back up system is no longer switched on the full scheduled time anymore. At most, the electricity back up will switch on for less than 45 minutes and my water is hot and sufficient for the whole family. Prior to Aqua Therma installation, my geyser was always on electricity back up because the solar was not heating up the water efficiently. I was also advices to install the Ubertrac monitoring system which is linked to my home wifi. Now i can check the performance of my geyser anywhere in the world. What impressed me the most was that, after installation, Aqua Therma will monitor the performance of your geyser daily via the internet. Any possible adjustments required, they will advice you and help you through the understanding of how the system operates. They even insulated my geyser and pipes for me to prevent heat loss. I am so impressed by their service and i would recommend aqua therma anytime because i have seen value in their services. The Director of the company, Cameron, monitored my system daily and was always available when clarity is sought. The sweet part of all this, their rates are so reasonable and i am so happy with their services.

Highly highly recommended. Cameron and his team provided excellent service from start to finish. From day one I was given adequate information to make a decision to do the conversion. Cameron followed up and even had a video chat with my husband to explain the system. His quick response on messages are absolutely amazing. And the best of it all is that we could see a massive improvement on our electricity use in only 2 weeks. By now we would have needed to buy more electricity, but with this conversion we have more than enough units remaining for the rest of the month.

This was by far one of my best investments.Aqua Therma installed 24 Panels for me 4 months ago and since then my electricity bill was cut by half.What is even more satisfying is the continuous care .

Since installing a solar geyser from Aqua Therma, my electricity bill has halved. The system comes with an app on which I monitor how much hot water is available anytime. God's sun makes boiling hot water, no price increases!

I can highly recommend Aqua Therma to convert your current geyser to Solar - Cameron and his team provided us with excellent service from start to finish. Deola, who was my first point of contact was such a friendly and informative representative of this new company. We decided to convert our current geyser to Solar after being without power for 10 days due to our mini substation being vandalised ( still no power 3 weeks later ) The 30 tube system is working perfectly - Our water is in fact hotter than usual and warms up much quicker than before. We received 4 quotes to convert our geyser, and although all prices were very similar, we were very pleased with Aqua Therma's product and service. Thank you Cameron and Team!

We converted both geysers in our house to solar with the help from Aqua Therma. Very happy with it and even though I expected that we would have had to change habits in using hot water it was not required. Cameron's assistance with taking me through the application to manage the geysers' heating if required was very helpful.

Recently had a solar installation done by AquaTherma and am very happy with the service and professionalism. The system is working extremely well and is easy to configure based on individual requirements. Great ability to monitor performance and I would highly recommend to anyone looking for cost savings and less reliability on Eskom Dustin Bryanston
