As a company that’s been elbows-deep in gas installations across Cape Town for over a decade, we’ve seen the good, the bad, and the downright inefficient when it comes to home water heating.
One of the questions we get asked the most, especially from homeowners looking to stretch their rands, is this: “Are gas geysers really cheaper than electric ones?”
The short answer? Absolutely. But before you rip out your electrical appliances, let us explain why.
The Real Cost of Heating Water
Electric geysers are the old standard. They are reliable, familiar, and relatively simple to install.
But they’re also massive electricity guzzlers (which is why Eskom always asks users to turn off geysers when we’re loadshedding).
A traditional electric geyser keeps your water hot all day, even when you don’t need it, which means it’s constantly drawing power and pushing up your electricity bill.
Gas geysers, on the other hand, work on-demand.
No hot water needed? No gas is burned.
It’s as simple as that.
You only pay for what you use, and in a country where Eskom has us holding our breath daily, that’s not just cost-effective, it’s common sense.
What the Numbers Say
Depending on the size of your household and water usage, a gas geyser can reduce your water heating costs by 30–50% per month. I’ve had clients who cut their electricity bills in half just by switching their geysers to gas.
Over a year? That’s thousands of rands back in your pocket.
And let’s not forget installation costs.
While a gas geyser installation might be slightly more upfront, because you need certified technicians and proper ventilation, the long-term savings far outweigh that initial spend.
Plus, there are compact models that are budget-friendly and perfect for flats, holiday homes, or even off-grid setups.
Reliability During Load Shedding
This is where gas geysers shine like a beacon. When load shedding hits and your neighbour’s standing in a cold shower, you’re enjoying a hot rinse like it’s any other day. No inverter. No backup battery. Just clean, consistent heat powered by your gas supply.
Our Verdict from the Field
Now, are there downsides? Sure there are.
You’ll need to refill your gas bottles, and you’ll want annual servicing to keep things running safely and efficiently. But compared to the rising cost of electricity and the frustration of inconsistent power, gas still wins the value battle hands down.
As someone who’s installed everything from five-star hotel systems to humble backyard cottages, I can tell you, gas geysers aren’t just a smart financial move. They’re the way forward for energy-conscious, budget-smart South Africans.
