In a bold move to tackle South Africa’s ongoing energy challenges, Vodacom Business, Sensor Networks, and Ariston have joined forces to revolutionize home energy management. Their strategic partnership is centered around one of the most energy-hungry appliances in the home: the geyser.

Smart Geysers, Smarter Savings

At the heart of this collaboration is Sensor Networks’ smart geyser technology, which allows homeowners to control their geysers remotely via smartphone. With features like temperature adjustments, scheduling, and remote switching, users can optimize energy use throughout the day. This not only supports solar integration but also prepares households for future time-of-use tariffs, helping them save money while easing pressure on the national grid.

Real Impact, Real Numbers

With over 12,000 smart geysers already installed, the results are impressive:

• R400+ monthly savings for large households
• 50,000 kWh saved daily
• 18 GWh saved annually
• R55 million in total yearly savings at current electricity rates

These figures highlight the potential of smart technology to make a tangible difference in both household budgets and national energy stability.

A Connected Future

Vodacom Business brings its Global Data Service Platform (GDPS) and robust network infrastructure to the table, ensuring seamless connectivity for smart geysers—even in remote or hard-to-reach areas. This connectivity is crucial as Sensor Networks prepares to scale its energy management platform across Africa.

Beyond Energy Efficiency

The benefits go beyond just saving electricity. Geysers are a leading cause of insurance claims due to water damage. Sensor Networks’ technology detects early signs of failure—like leaks or overheating—and automatically shuts down the geyser, preventing costly damage and improving customer satisfaction.

Accessible, Scalable, and Home-Grown

Unlike solar or gas alternatives, which can be expensive and slow to pay off, connected geyser technology offers an affordable, immediate solution. As Wayne Vertue of Ariston SA puts it, “South Africans can start saving from day one.”

Malcolm Subramony of Vodacom Business adds, “This is a proven, home-grown solution that delivers results. If adopted at scale, it could significantly reduce pressure on the grid—without the need for costly new infrastructure.
