As the winter chill settles across South Africa, many of us are reaching for quick solutions to keep our homes warm. The small, portable fan heater is a household staple—it is cheap to buy, lightweight, and provides instant, comforting heat.

The topic took center stage on the Good Morning Breakfast show, where the team debated the best ways to fight the freeze without destroying the monthly budget. While these compact devices are gentle on your wallet at the checkout counter, they can be devastating to your electricity bill. With NERSA-approved tariff hikes driving winter 2026 electricity prices to an average of R3.80 per kilowatt-hour (kWh), running a fan heater might be costing you far more than you realise.

Here is a breakdown of what that small fan heater is adding to your monthly utility bill, and how you can keep warm for less.

The Hourly Breakdown: Decoding the Wattage

Most standard fan heaters operate on two power settings: a low setting of 1000 watts (1 kW) and a high setting of 2000 watts (2 kW).

When translated into municipal electricity units at the 2026 average rate, the costs look like this:

• On the Low Setting (1000W): The heater consumes exactly 1 unit of electricity per hour, costing you R3.80 per hour.
• On the High Setting (2000W): The consumption doubles to 2 units of electricity per hour, costing a staggering R7.60 per hour.

The Cumulative Shock: Monthly Projections

An hourly rate of R7.60 might sound manageable, but space heaters are rarely used for just an hour. When left running on high throughout the month, the math quickly becomes alarming:

• 3 hours per evening: R22.80 per day / R684.00 per month
• 5 hours per day: R38.00 per day / R1 140.00 per month
• 8 hours (e.g., overnight): R60.80 per day / R1 824.00 per month

Adding nearly R2,000 to your monthly bill just to keep one room warm overnight is a heavy financial burden for most households.

The Efficiency Trap: Why Fan Heaters Cost More for Less

The real issue with fan heaters is not just the power they draw, but how they distribute it. Fan heaters create directional, convective heat. They warm the air directly in front of them, but because air cools rapidly, the room loses its warmth almost the exact moment the appliance is switched off. They offer zero heat retention.

Using a fan heater to warm a medium-to-large living room is an uphill battle that forces the appliance to run constantly on its highest setting, draining power without ever truly warming the space.

Team Insights: How the Good Morning Breakfast Crew Beats the Chill

During the on-air discussion, it became clear that the team has very different strategies for surviving the winter months economically.

• Shandor’s Choice: Shandor firmly favours the electric blanket. Economically speaking, he is spot on. At roughly R0.46 per hour, an electric blanket costs up to 95% less to run than a fan heater, proving that warming your body is far cheaper than trying to warm the air in an empty room.
• Margaret’s Choice: Margaret’s favourite winter appliance is, surprise surprise, the kettle. While a kettle draws a high amount of power (up to 3000W), it only runs for about three minutes at a time. This means boiling water for a hot beverage or a cozy hot water bottle costs a mere R0.38 per boil—making it a highly affordable way to get an instant temperature boost.

Smarter, Cheaper Ways to Fight the Freeze

You do not have to freeze to save money. By switching your heating strategy, you can maintain comfort at a fraction of the cost:

1. Follow Shandor's Lead: Switch to electric blankets for targeted warmth while watching TV or sleeping.
2. Utilise Heat Pumps (Air Conditioners): If you have an air conditioner with a heating mode, use it. Modern inverter air conditioners are highly efficient heat pumps. They can heat a room using up to 50% less electricity than a standard fan heater.
3. Invest in Radiant Heat: For heating entire rooms over longer periods, oil-filled radiators or panel heaters are far more efficient. They take longer to heat up but continue to radiate warmth into the room long after they are turned off.

The Verdict

Small fan heaters are excellent for a quick, 10-minute blast of heat to take the edge off a freezing morning. However, using them as a primary winter heat source is a financial trap. Take a page out of the Good Morning Breakfast playbook this winter: target your heating, stick to the basics, and keep your hard-earned money in your bank account.
