Conventional water heating costs 40% of your total electricity bill

Consumers and businesses are bracing for a reported 20% Eskom price hike in April 2018 – just seven months away. On the current trajectory, households currently spending R2000/pm on power can expect that same electricity to cost R5000/pm in five years. Over the next 10 years, the same household will spend R500k on electricity – the cost of a small townhouse and double the cost of a university education.

When you do the sums and look at what your money could be doing from an investment perspective, it’s very clear that finding alternatives to Eskom’s over-priced and unstable grid electricity is an imperative for every South African household.

Slash at least 30% off your total electricity bill with solar or a heat pump solution

The best place to reduce your electricity bill with a big margin of around 30% is by converting hot water heating to a renewable solution such as solar or a heat pump.  Heating up your household water in a conventional electric geyser consumes the largest chunk of your total household electricity bill – on average 40% of your total costs go to hot water.

Furthermore, if you have plans to generate your own electricity by means of photovoltaic solar power (PV) which many homeowners are opting for, you need to work towards getting your house ‘PV-ready’ by reducing your electricity usage and becoming more efficient – the geyser is the primary starting point.

Heat Pump or Solar?

When it comes to water heating, solar is a well-known and very effective alternative when sized correctly, while heat pumps are ideal for households and businesses where solar water heating would not be a viable alternative due to too much roof shade, roof structure challenges, aesthetic considerations or high hot water usage that solar would not be able to keep pace with.

There is no right or wrong answer and both solar and heat pump technologies will deliver a very sizeable saving on your electricity bill.  Conservatively, savings are placed at around 30%, while we have many client testimonials where the savings have been much higher. The decision between solar or heat pump will depend on a number of important considerations that One Energy will determine based on your specific needs analysis.

The investment case for a heat pump

Based on electricity bills where households are spending between R1800 to R2800 per month, the installation of a 5.6 kW heat pump at an installed cost of around R 22 000 will provide an immediate and conservative 25% saving on your total monthly electricity bill, and cut 70% of your annual water-heating costs.


Eskom’s hyper inflationary increases aren’t about to go away as the utility finds itself in a serious financial and leadership crisis.  Even if you take a conservative approach with an average 15% increase which is likely for the next five years and at least 8% for years six to 10, you’re going to be coughing up a huge amount for electricity if you don’t do something about it now. There’s no doubt that installing a heat pump or solar water heating solution will dramatically reduce energy consumption, save thousands of Rands over the years on your electricity bill and make a significant contribution to getting your home ready to go off-grid with PV.
