With Stage 3 load shedding now a long-term reality for South Africans, homeowners are seeking smarter, more energy-efficient solutions to maintain daily comfort while reducing reliance on the national grid.

Kwikot is shedding light on how shifting consumer preferences are shaping the future of sustainable water heating in South Africa.

 

Rising Electricity Costs Driving Change

Historically, over 95% of South African households have relied on electric geysers for hot water. However, skyrocketing electricity prices – rising more than six times inflation since 2008, together with ongoing load shedding have accelerated the adoption of alternative energy sources. Homeowners are now prioritising energy efficiency over upfront costs, as they seek long-term savings and uninterrupted hot water supply.

 

The Shift Towards Alternative Water Heating

While electric geysers still dominate the market, solar photovoltaic (PV) water heating and heat pumps are emerging as preferred solutions due to their reliability, long-term savings and reduced environmental impact. The decreasing cost of solar PV panels down 90% over the past 15 years has made this option particularly attractive.

“Homeowners are realising that investing in an energy-efficient water heating system is no longer just about sustainability, t’s about economic survival,” says Sean Moolman from Power Optimal, a Kwikot partner. “Load shedding and electricity hikes are forcing South Africans to rethink how they heat water and solar PV water heating is fast becoming the go-to choice.”

Government regulations, such as the National Building Regulations (SANS 10400-XA), require at least 50% of new buildings’ hot water to come from non-grid energy sources. This has driven increased investment in solar geysers, heat pumps and hybrid water heating systems.

 

Smart Water Heating: The Next Frontier

While still in its early stages in South Africa, smart home integration is gaining traction. Advanced geyser controllers, automated scheduling and energy monitoring tools are becoming more popular, especially among property developers and high-end homeowners. “As technology improves and awareness grows, smart water heating solutions will play a critical role in South Africa’s energy future,” adds Moolman.

 

Looking Ahead: The Future of Water Heating

With load shedding expected to remain a persistent issue, experts predict that solar PV water heating will see the highest adoption rates in the next 5–10 years. Additionally, financing options such as solar loans are enabling homeowners to prioritise energy efficiency without the burden of high upfront costs.
