Are Electric Geysers Dead? Why It’s Time to Go Solar

In a city like Johannesburg, where energy challenges and infrastructure instability are an everyday reality, relying on outdated technologies is no longer just inefficient, it’s unaffordable. One of the biggest culprits? Traditional electric geysers.

Electric geysers have long been a household staple across South Africa. They’re familiar, easy to install, and once seen as reliable. But in 2025, with electricity prices soaring and load-shedding back with a vengeance, continuing to use these outdated systems is becoming a financial liability.

Electricity Costs Are Spiralling

The National Energy Regulator of South Africa (NERSA) approved a 12.7% electricity tariff increase for 2024/2025. This translates into an average household electricity bill rising by hundreds of rands monthly. With electric geysers accounting for roughly 40% of a typical home’s electricity consumption, that’s a massive, avoidable expense.

Load Shedding Is Still a Threat

South Africans know the pain of unreliable power all too well. Even with long-term energy strategies in place, the national grid remains unstable. Electric geysers can’t function during outages, leaving families without hot water during critical times.

So Why Are People Still Sticking with Them?

There’s a lingering myth that solar geysers are too expensive or ineffective in winter. But that couldn’t be further from the truth.

Let’s Debunk Some Common Myths:

  • “Solar geysers don’t work in winter.” Modern systems include electric backup elements that activate only when needed. Johannesburg still receives over 2,500 hours of sunlight annually—ample for efficient solar heating.
  • “They’re too expensive.” While upfront installation can range from R15,000 to R35,000, homeowners often recoup costs within 3–5 years. 

The Benefits Are Undeniable:

  • Reduced monthly energy bills by up to 50%
  • Lower carbon emissions
  • Added property value
  • Energy independence

At Plumbing Johannesburg, we work with accredited solar geyser suppliers and offer installation packages tailored to each home’s unique energy needs. Our systems are SABS approved, come with 5 to 10-year warranties, and comply with all PIRB and IOPSA installation standards.
