In the past property owners had the choice of which energy source to use when it comes to water heaters. Nowadays, legislation in South Africa states that at least 50% of your water heater needs to be some form of renewable energy.
This new legislation leaves you with two options – gas or solar. While gas geysers only produce about 30% of the greenhouse gas emissions of electric water heaters they still require the purchase of gas to keep it running. Solar geysers, however, only requires a once-off investment which after it will provide you with almost 90% of your hot water needs daily.
As South Africans, we are lucky that we receive year-round sunshine which makes the option of a solar geyser even more attractive. Below are the pros and cons of choosing solar geysers.
Pros of Solar Geysers
- A solar geyser can help you save up to 90% on your water heating costs. It also lowers your energy bill significantly and doesn’t require a mains connection.
- Free and renewable energy at all times – solar geysers will continue to heat your water even on cloudy days.
- Solar power reduces our dependence on fossil fuels, allowing us to use renewable energy that would have been wasted otherwise.
- It also limits smoke, gas and chemical by-products.
- The quality of the water doesn’t influence the solar geyser system.
- Since you don’t have to rely on electricity to supply the hot water, it will benefit homes with no access to electricity.
- Solar heating systems are strong and weather resistant. Tubes are able to withstand frost and hail.
Cons of Solar Geysers
- It requires an upfront investment that can be costly to some
- Routine maintenance on the valves are needed, but not on the system itself.
As you can see the pros of installing a solar geyser in your home far outweigh the cons. For more information or if you are interested in a free quote, speak to the team at Nupower today.
