Understanding Water Heating Technologies

We’re committed to helping you make informed decisions about energy-efficient solutions for your home or business. Today, we’re diving into the world of water heating technologies.

Comparing Water Heating Technologies

We’ve analyzed different water heating options to help you understand which technology could save you the most. Here’s what we found for a family using 200L of hot water daily:

  • 1

    Heat Pump: The winner! Saves R62,415 over 5 years

  • 2

    Solar Thermal: Great option, saving R50,841

  • 3

    Solar PV (4 panels): Solid choice, saving R37,462

  • 4

    Instantaneous Gas: Modest savings of R17,025

Why Heat Pumps Are Our Top Recommendation

Heat pumps are the most efficient because they use a small amount of electricity to move heat from the surrounding air into your water, rather than generating heat directly. This makes them incredibly energy-efficient, saving you money while reducing your carbon footprint.

Key Considerations for Each Technology

  • Instantaneous Gas: Best for areas without electricity, but consider gas supply logistics.

  • Solar PV: Ideal for multi-story buildings where the geyser is far from potential solar panel locations.

  • Solar Thermal: Great return on investment, but proper sizing is crucial.

  • Heat Pumps: Offer the best savings and flexibility in usage patterns
