Conventional Water Heaters Use Energy
According to mechanical engineers at the University of Wisconsin’s Solar Energy Laboratory, an average four-person household with an electric water heater needs about 6,400 kilowatt hours of electricity per year to heat their water. Assuming the electricity is generated by a typical power plant with an efficiency of around 30 percent, it means that the average electric water heater is responsible for about eight tons of carbon dioxide (CO2) annually, which is almost double that emitted by a typical modern automobile.
The same family of four using either a natural gas or oil-fired water heater will contribute about two tons of CO2 emissions annually in heating their water.
Conventional Water Heaters Pollute
Surprising as it may seem, analysts believe that the annual total CO2 produced by residential water heaters throughout South Africa is roughly equal to that produced by all of the cars and light trucks driving around the country.
Another way of looking at it is: If half of all households used solar water heaters, the reduction in CO2 emissions would be the same as doubling the fuel-efficiency of all cars.
The above represent solid reasons to go solar. As with other products on offer through Grey Water Systems the benefits are both environmental and economical. In the long run your solar geyser will pay for itself in around 3 years and your rainwater harvesting\grey water system in about as much time (based on current water prices). Our mission here is promote sustainable living spaces-to work towards a country which has as its main premise the notion of sustainable living and sustainable development. Imagine knowing that you are personally stopping TONS of CO2 emissions from entering our atmosphere every year AND saving thousands of litres of fresh water-The feel good aspect of our systems speak for themselves.
