Who Aqua Therma Supports
We work with homeowners, landlords, sectional title bodies, and small businesses who want to cut electricity bills and enjoy consistent hot water. Whether you’re upgrading an existing electric geyser to solar or planning a new build, we make the process clear and straightforward from the first conversation.
Solar Geyser Retrofits and Conversions
Most electric geysers can be converted to solar without replacing the tank. A retrofit adds a high-efficiency solar collector, circulation components, and a controller—reducing energy use while keeping your existing cylinder when suitable. If your tank is too old or small, we’ll suggest the best replacement for long-term performance. Contact us for a free, no-obligation assessment. Our experienced team will also explain how your new system works, including tips on getting the best efficiency year-round, so you can enjoy reliable hot water with minimal running costs.
Ongoing Support and Servicing
We provide regular servicing, system checks, and repairs. If another installer fitted your system and it’s underperforming, we can quickly assess and fix it. We keep common parts in stock to complete many repairs on the first visit.
Business Hours and Service Areas
We serve Gauteng and nearby areas. Hours: Monday–Friday 8:00–17:00, Saturday 9:00–13:00. Messages sent outside these times are answered promptly when we reopen.
