Solar Water Heating

South Africa is blessed with perfect climate to obtaining energy from sunlight throughout the year.
Solar Water Heaters collects the heat from the sun, generate it through the solar collector with the heat transferred through the collector (or panel) and store it in the water vessel or tank. Hot water from the tank can then be used for various applications whenever needed. A Solar Water Geyser works on the basis that cold water is heavier than hot water. As water builds up heat and gets warmer the molecules are moving quicker and have less weight than cold water.

A Solar Water Geyser works on the basis that cold water is heavier than hot water. As water builds up heat and gets warmer the molecules are moving quicker and have less weight than cold water.

The biggest myth is that, if you have a Solar Water Geyser, you will only have hot water if the sun is shining. Fact is that you will have hot water whenever you want and need it. Water gets heated due to diffused radiation available in the atmosphere, but when it is raining or at night, when the sun is not shining at all, your high pressure solar water geyser can be switched to electricity to heat your water to the temperature you want or need.

 

WHY IS SWITCHING TO A SOLAR WATER HEATING OPTION IMPORTANT

Your geyser or hot water cylinder is the most energy intensive appliance in your home – and the most expensive to run. The good news is that solar geysers can replace up to 60 – 80% of the electricity used to heat water, making solar water heating one of the first steps you need to consider in energy and cost savings. It provides the best return on investment in comparison with other renewable energy saving or generating technology.

Therefore, during any energy savings project, Winelands Solar will advise their clients to either convert the existing electric geyser to solar or install a solar geyser as step no 1 to any solar energy solution.

You start saving immediately – up to 60 – 80% of the electricity to heat water and 40% of your electricity bill (depending on the household).A Solar Water Geyser pays itself off within 2 – 3 years without a doubt.

THE POTENTIAL SAVING BY SWITCHING TO A SOLAR WATER GEYSER

To understand the extent of the saving of a Solar Water Geyser, it is important to know how the financial equation is calculated. The formula is to take the volume of water to be heated, the “temperature differential” (minimum and maximum temperature of the water) and the amount of power to heat the volume by the temperature differential.

Look at the SESSA website to understand the calculation (http://sessa.org.za/solar-water-heating/solar-water-heating-basics).

INCREASE THE VALUE OF YOUR HOME

A Solar Water Heating Appliance will add thousands to the value of your home. A solar water geyser or Heat pump is the only appliances in your home that can really save you money and the savings will blow your mind.

A Solar Water Geyser is an investment and therefore you need to make sure that you partner with a Solar Company who insists on value but do not compromise on quality.

When shopping for a solar geyser, make sure you talk to suppliers who know the pros and cons of the specific brand, model and type. Some imported solar geysers may seem cheaper, until there is a malfunction and you have nowhere to send it back to. Rather invest in a well-known and trusted brand and use a registered company (and make sure the company is a member of Sessa)

ENVIRONMENTAL ACCOUNTABILITY

A Solar Water Heating system will not just benefit your pocket, but it will also be a victory for our environment. Our clients are responsible individuals motivated by the idea of independence and environmental responsibility.

A Solar Water Geyser secures your independence from Eskom and fixes your electricity bill for decades to come.

Using the free energy potential of the African sun is smart and a very clever choice.

The average household can reduce its CO2 emissions by as much as 20% by installing a Winelands Solar Geyser, contributing to a cleaner and more sustainable environment at the same time

 

 

 

 

UNDERSTANDING THE SOLAR WATER HEATING TYPES

All Solar water heaters do the same thing. They gather the heat from the sun through the solar collector and transfer that heat to the water which is then stored in a vessel (the geyser or tank). It is thus the conversion of sunlight into renewable energy for water heating, using a solar thermal collector.

\r\n

The levels of efficiency are determined by quality and size of the collector. Winelands Solar only uses high quality collectors through our partners.

FLAT PLATE VS EVACUATED TUBE COLLECTORS

The solar collector is a flat plate collector or an evacuated tube collector.

The choice between a flat plate and an evacuated tube is based on the graduation and direction of your roof. An evacuated tube system performs better than a flat plate collector. On a roof which faces west or east, an evacuated tube system will perform better than flat plates and therefore the recommended option by the Winelands Solar Team. However, some clients want the look of a flat plate better.

\r\n

We suggest an evacuated tube system if your roof’s orientation is more than 45˚ off North (to either West or East)
