Genergy’s Energy-Efficient Hot Water Solutions

…as well as a little about greenwashing, greening tips, and then some surfing.

Hi and welcome to our second ever Genergy newsletter. We at Genergy hope you are well and that the year is treating you good. It looks like it’s going to be a challenging back half, so we’re suggesting that you take advantage of some of that free energy that pours down on us in South Africa, and save yourself some money. We can show you how.

As it is, you’re on our mailing list because you’ve either done business with us in the past, or you have expressed interest in our company and our products somewhere along the line. We always promise to not bombard you with irrelevant information and content, but if you don’t want to be on the mailer, please unsubscribe using the link at the bottom of this newsletter, and accept our apologies in advance.

Genergy’s Energy Efficient Hot Water Solutions

First up, we want to tell you about some of our hot water solutions. Genergy has been in the large-scale hot water space for 10 years, and has installed some massive plants with great success across South Africa over this time.

We use two types of technology to achieve the best savings for heating plants for our clients.

1. Thermal Heating

2. Heat pumps

Genergy has designed and installed one of the biggest thermal heating plants in South Africa. This plant, on a mine, heats 100 000L of water per day by means of 160 evacuated tube collectors (4800 evacuated tubes), and hundreds of miners utilise the hot water for their post-shift shower. This thermal plant provides a saving of about R100,000 per month to the mine. Genergy has numerous similar plants across South Africa, and we maintain all our plants ourselves.


This (above) is a Solar thermal heat pump hybrid hot water system, consisting of 4 banks of 40 collectors each, and 4 x 15 000L HW storage vessels with a 45kW air source heat pump each.

Genergy also specializes in large-scale heat pump plants. These plants can be found in the mining, industrial and residential sector. These plants are a great investment as the return on investment is generally less than 1 year and the plant has a life expectancy of 10 years.

The Subtle Art Of Greenwashing

Greenwashing is a term that has come into play fairly recently, but is becoming heard more and more often as companies around the world try to portray themselves as environmentally responsible.

According to the Oxford English Dictionary: Greenwashing is disinformation disseminated by an organization etc., so as to present an environmentally responsible public image. It’s not a complimentary term, and people or companies who utilise Greenwash practices are being deceitful.

Examples are companies that simply state that they have eco-conscious practices in place, but don’t provide any proof, companies that provide irrelevant information in a bid to portray themselves as green, and companies that blatantly lie about their environmentally conscious systems. Another way is to use ‘green’ packaging to sell products, or falsely utilize words like ‘Eco’ or ‘Bio’ in their packaging.

Greening Tips For The Home.

It’s not expensive to start greening your home, and it’s not very difficult either. Remember that it’s the small things that count, and that add up to make a difference. Here are a few easy eco compromises you can make without breaking into a sweat.

1. Switch all your lightbulbs to LEDs (or at least switch a few). It is a bit of outlay to switch, but LED’s are extremely energy efficient, and last for a long time. Savings are immediate as well.

2. Remember that your hot water consumes more than 40% of your household electricity bills. By installing a solar geyser you can save 90% of your hot water usage.

3. Your kettles has a 2kW element, so best to only fill the kettle with the correct amount of cups needed as opposed to filling it up. This will result in good savings.

3. Buy a cheap reusable water bottle, and stop buying disposable plastic bottled water. Then watch this little 8-minute video called – The Story Of Bottled Water:

4. Wash your clothes in cold water instead of hot whenever you can. Your washing machine uses up to 85% of its energy on a cycle just heating the water up. Also, line dry your washing, and ignore the tumble dryer– it sucks electricity.

5. Turn off the lights when you leave the room, and don’t turn on lights at all for as long as you can. If the sun’s out, open your curtains and enjoy natural light.

6. Change all your outside lights to lights with day/night sensors. This will ensure that your lights switch off first thing in the morning to save on electricity costs.

7. Turn off your computer completely at night and unplug all unused chargers and appliances.

Genergy At The JBay Open

It’s that time again when the best surfers in the world descend on JBay for the annual JBay Open professional surfing event.

Last year, I’m sure many of you remember, was the year that Australian surfer Mick Fanning had an encounter with a Great White shark during the final, and walked away unscathed. Well, apart from the odd shark, another characteristic of the event is the freezing cold water, and those icy winter southwest winds. The surfers come in after their heats and they’re so cold their feet are numb.

Lucky for them Genergy has solar showers set up for these athletes to rinse off and get some warmth on them after their heats. Genergy has been involved with the surfing event at JBay for a long time now, and will continue with the tradition going forward. See you down there!
