Using Free Energy from the Sun to heat water is the best use of solar energy. Today, millions of homes and businesses around the globe use solar water heating systems because they are cost effective.

Solar Water Heating is the First Thing To Do when going solar! Solar water heaters are the most cost effective way to reduce carbon emissions and reduce dependence on imported energy.

Harnessing the sun’s energy to heat water makes sense, after all, it is one of the oldest uses of solar energy! Family’s water heaters consume more than 50 trillion kilowatt-hours of energy every year and creates millions of tons of pollution.

Did you know the Pure energy of the Sun produces enough power in less than one hour to meet our World’s Energy needs for a Year!

Shrink your Power Bill with the Pure Energy of the Sun! A powerful, attractive “Hi Temp” ZERO pollution water heater puts the sun’s energy to work in your home.  It will work hard for decades to shrink your high energy bills and cut environmental pollution for decades to come.

Flat-Plate solar collectors – durable, weatherproof boxes which contain a dark absorber plate located under a transparent cover – are still the most common type of collector used for water heating in many countries despite being inferior to evacuated tube collectors in many ways.

Evacuated heat pipe tubes are designed such that convection and heat loss are eliminated, where as Flat-plate solar panels contain an air gap between absorber and cover plate which allows heat loss to occur. Further, thermal heat pipe systems are capable of limiting the maximum working temperature, where as Flat-plate systems have no internal method of limiting heat buildup which can cause system failure. Finally, evacuated heat pipe systems are lightweight, easy to install and require minimal maintenance. Flat-plate systems, on the other hand, are difficult to install and maintain, and must be completely replaced should one part of the system stop working.

During the last two years, leading governments worldwide have committed over $180 billion dollars to sustainable energy, according to the Global Trends in Sustainable Energy Investment report. Financial investment in developing countries has increased over 27 percent to $36.6 billion, with over $1.1 billion going to Africa alone. Total investments in the renewable energy sector reached over $117 billion with $33.5 billion going directly to solar energy projects. The drivers that have propelled investment in the sustainable energy sector so dramatically for the past five years are still at work—climate change, energy insecurity, fossil fuel depletion and new technologies.

After several  months of investigation, the outcome is what most South Africans expected. The rebate does not have any impact on what the consumer pays but put more money in the suppliers pocket!

The fact is most companies that offer the Eskom Solar Rebate inflate the price of the entire system. We have done our homework and compared apples with apples only to find that a system that Hi Temp Solar installs is sometimes up to 50% lower priced than that of a system installed by an Eskom accredited company.

How is this possible?

1. Companies that are accredited by Eskom must have their complete solar systems tested and approved by SABS even if they have a CE approval. These tests can take up to 6 months and cost anything from R45,000.
2. There are at least 1/2 a dozen different installation options which means that each set-up must be tested and approved by SABS.

With just the two above points the costs are astronomical and someone has to pay for this. This cost value is passed onto the consumer which naturally increases the entire installation costs.

So to put this all in a nut shell-

• If we supply you with a solar system that IS NOT Eskom
• Accredited the cost will be on average R10500 incl. VAT.
• If we supply you with a Solar System that IS Eskom Accredited the cost will be on average R17800

You would then need to complete the Eskom Claim form and submit it and wait for about 20-25% rebate. Who know how long the rebate payout will take? When you eventually do get the rebate paid back to you will be in a position where you will still have paid more for a Non Eskom Accredited system! FACT!!!

Eskom rebates on solar water heating systems

Eskom’s Solar Water Heating Programme, introduced at the beginning of 2008, has undergone a major change that brings it into line with international practice.

With immediate effect consumer rebates will now be paid directly to consumers and not to the installing supplier. In order to claim the rebate for the system fitted by approved Eskom suppliers, the purchaser will submit a claim for the rebate to Eskom’s auditors who are facilitating and monitoring the process.

The rebate system is not in anyway exclusive. The requirements of a supplier to sell systems that qualify for rebates are the following:

• Be able to offer a 5 year guarantee
• Submit documents, including public liability and company details
• Have system tested AND passed at the SABS for the following;
  • Safety
  • Mechanical
  • Thermal

The choice of what systems are submitted for testing is solely up to the supplier.

Important: No rebates are paid for systems which were installed before your system, your supplier or your installer were registered on the programme.

Solar Heating (Solar Thermal) Systems

Using solar power to heat your water is one of the most practical and cost effective ways to harness energy from the sun. Solar thermal systems absorb the sun’s heat and use it to heat your residence’s own hot water needs. In general, the solar thermal system will easily heat water to 140ºF or higher matching the range of its traditional hot water tank counterpart. Effective systems can collect up to 70 percent of the sun’s energy that reaches them and transfer it to you.

How Solar Hot Water Heating Systems Work

In general there are two types of active water heating systems: direct and indirect.

Direct Solar Water Heating

As implied, direct systems capture the sun’s heat in collectors to directly heat a household’s water supply. The system consists of collector pipes filled with water that are linked to an insulated storage tank usually located inside a home. As the sun heats the water inside the pipes, the water flows into the storage tank. Although direct systems are more efficient that indirect ones, they require more maintenance to keep the pipes clear of mineral deposits. Direct solar thermal systems also work best in warmer climates where the system is less prone to freezing.

Indirect Solar Water Heating

Indirect systems do not heat the water directly rather they use fluid with a low-freezing point to absorb radiant energy from the sun. Also termed closed-loop systems, an indirect solar water heating system absorbs the sun’s rays into heat pipes evacuated of air which in turn heats up the pipe’s thin copper laminate located on the back of each pipe. The collection array consists of multiple heating pipes that are mounted and tilted to maximize solar collection.

Often glycol (an ingredient in antifreeze) runs through adjacent pipes within the array and heats up via contact with the copper laminate. As the temperature in the pipes rise, the heat activates a pump that circulates the glycol fluid through a heat exchange coil in the water tank. That coil, in turn, transfers its heat to the water tank and voila, hot water is produced.

Solar Pool and Hot Tub Heating Systems

Solar pool heating systems work on a similar principle to a direct system solar hot water heater. However, because the water can heat up too much in a solar thermal system, the collector’s glazing is often removed. Using non-glazed pipes or a heating system that resembles a flat black mat prevents the pool water from becoming super-heated as well as reduces costs to the overall system.

While solar pool and hot tub heating systems often are exempted from federal and state monetary incentives and rebates, they often pay for themselves within 1–5 years (depending mostly on where you live).

Radiant Heating Systems For Your Home

You can also use a solar hot water (or thermal) system to heat your home. Rather than transferring the heated water to a domestic hot water heater, the solar hot water system can connect to a radiant floor and/or wall panel radiator.

You can make the collection and distribution system as simple or complicated as you like depending on your location, climate, and intended use. Most radiant heating systems use the collection array to heat water and store it in a large thermal collection tank so that you have enough heat to last at least throughout the night. A general rule of thumb is to have a collection tank that can store 1½ to 2 gallons of water for every square foot of solar collector. That water, in turn, is piped via plastic tubing under floors to create an effective heating system.

Radiant floor heating systems have many advantages. They are typically 40 percent more efficient than a forced air heating system and can be zoned so that each room has its own thermostat. Furthermore, radiant floors distribute heat beneath your feet where it naturally rises providing a cozy and evenly distributed heated living space.

Tips for Installing Solar Hot Water Systems

Solar Hot Water Heater Tips for Cooler Climates

In cooler climates during the colder times of the year, an indirect solar hot water system can help lower your energy costs by working as a water preheating system rather than an outright water heater. Preheated water reduces the load on your other energy systems to heat the water.

Another trick to increase the system’s efficiency is to wrap your water tank with an insulation blanket to keep the water sufficiently warm and further minimize the need to rely on traditional power sources to heat your water. (Note that not all water heaters need an insulation blanket. Many of the newer energy-efficient models come with a thicker layer of insulation inside the tank that eliminates the need for additional insulation).

Where to Place a Solar Thermal Collection System

Like other types of solar energy systems, solar hot water heating systems work best on south-facing walls with full sun exposure. Because of the collector tubes’ type of construction, the outside elements have less effect on its performance compared to a photovoltaic collection system; a bit of shade on the thermal array will have a less noticeable impact.

Work with a Hi Temp

As with any solar power upgrade, consulting with a solar professional can help you evaluate your potential savings and determine the type of solar hot water system that’s best for you. Solar thermal panels come both as stand-alone collection arrays and as integrated building panels. A solar pro can size your system and help you compare the different options for the collection panels and water tank you may need. And remember, solar domestic water systems often qualify for rebates!

TIRED OF INCREASING ELECTRICITY COSTS? INSTEAD of PAYING IT to ESKOM pay it to your CREDIT CARD and at least get something for it!!!

CUT R350-00 per month of your current electricity bill by converting your existing geyser to accomodate a high efficiency evacuated solar heating panel. This amount will even be more with larger geysers and larger  families.

CAPE TOWN has more than enough U.V. Rays (ultra violet) to heat an average size geyser 365 days of the year with little or no electrical assistance. This is a fact. I have a system installed at my home 12 months ago- From Sept to May I ran my house hot water needs entirely on the evacuated solar heating system. IT WORKS!!!!!

We supply and install:

• 1x Evacuated solar tube panel to suite existing geyser size

• 1x AC Low Wattage circulation pump

• 1x P6 Advanced Solar Control Panel to regulate the AC circulation pump

• 1x Copper conversion fitting water jet  

How it works:

When the sun comes up, the evacuated solar panel produces heat. The circulation pump draws the water from your geyser, pushes it through the evacuated solar tube panel heat exchanger and returns it back to your geyser. The circulation pump will only switch on if the P6 Advanced Solar controller instructs it to do so. The instruction will only happen if the P6 advanced controller detects that the evacuated solar panel is 10′C hotter than the geyser water temperature. This process is continued throughout the day, until the sun goes down and the pump automatically switches off. The Geyser thermostat temperature can be adjust using the P6 Advanced Control Panel as well as the element run times as back up. This ensures that on days where there is absolutely no UV rays around, you will still have warm water. On average you can expect to save between R300 to R600 per month, depending on your water usage demand.

Glen Symes balks at the idea of Cape Town builders using anything in lieu of a heat pump to warm up a swimming pool. "Why wouldn’t they use a heat pump?" he asks incredulously.

Colin, the owner of Pooltopia Pools and Spas in the Western Cape is not alone. He’s one of many Cape Town pool builders who touts the benefits of using the product as an efficient means to heat a pool.

Its popularity is continuing to grow beyond the borders of South Africa to other hot-weather areas, where it functions best. The larger manufacturers now jump at the opportunity to marker these units, acquiring heat pump companies and targeting growing areas of interest around the country.

Though heat pumps are not ideally suited for installations where the weather drops below 8 degrees, they are popular in many extended swim season areas. Manufacturers agree that the market along the Sun Belt is far from saturated, and some even say the heat pump could become a hot commodity nationally. But pool builders and retailers in some potential areas still prefer traditional methods of heating, a choice manufacturers are hoping to change.

In dry, hot climates such as Gauteng, the heat pump is a welcome way to warm the pool in cooler months, as well as cool it during summer months. "My pool can reach 38 degrees," Glen notes.

While effective in trapping heat, humidity is not a must-have for a heat pump to work well. "They don’t need as much humidity as one would first think," Glen says. "That’s a common misconception."

One manufacturer notes a common combination of solar and heat pumps in the Cape Town. This would allow solar to take over during warmer months. Solar’s shortcoming is its inability to heat through the night after the sun has set.

Energy costs always seem to be on the rise. This is largely due to the fact that we are using more energy then is available. Eventually our current energy sources are going to be depleted. That is why so many people are looking into alternatives. They are trying out solar power.

Solar power may not yet be ideal for every situation, but one place it seems to be the perfect match is outside. Solar pool heat is a great example of a perfect way to use solar energy. It is ideal because your pool is going to be exposed to the sun and you are going to use your pool during the sunniest times of the year.

Solar pool heating involves one of two methods. It can be either passive or active. Passive solar pool heating involves simple methods and equipment. Active solar pool heating involves a bit more complexity. As the names suggest a passive system simply draws in the suns energy, while an active system actively collects the suns energy.

Passive solar pool heating is usually done with a solar blanket or pool cover. The cover soaks up the suns heat and traps in inside the pool to warm up the water. The downside is the cover can only be used when the pool is not being used and if there is not adequate sunlight then there will not be as much heat which can lead to colder water temperatures on occasion. Passive solar pool covers are quite easy to install. They usually have some sort of reel system that allows you to cover and uncover the pool without a lot of hassle.

Active solar pool heating involves collecting, storing and moving the solar energy. A solar panel, a battery and storage unit are all parts of an active pool heating system. Active pool heating systems can be complex to install, but they are more reliable then passive pool heating systems. To install an active pool heating system you need to run cables, install the panels and connect everything to the pool.

Whichever heating system you select for your pool-whether it be active or passive-it will ultimately be much cheaper than a gas or battery operation, which will require the constant replacement of limited inputs. They are also easier to install and much safer. Above all, the solar energy is free. You can save a bundle on your energy bills by using a solar pool heating system over other systems.

Heat Pumps Increasingly Popular with Pool Owners

As energy costs continue to increase, swimming pool owners are looking at alternative ways to heat their pools. One option, that is proving to be increasingly popular, is the use of pool heat pump systems.

A heat pump extracts heat from the air or the ground (soil or bedrock) and transfers the accumulated heat energy to the swimming pool water. Most swimming pool heat pump systems extract heat energy from the air by passing the air over heat exchangers, efficiently transferring heat energy to the heat pump evaporator. The heat that is extracted from the air would otherwise be wasted, being dissipated to the atmosphere.

Heat pumps are incredibly efficient. A typical modern system will consume around only 1kW of electrical energy to produce around 5kW of heat energy.

The initial cost of a heat pump system can be a little off-putting as they do cost somewhat more than conventional electric or oil based systems. For example, a typical heat pump system for an in-ground swimming pool may cost R8000. But this cost will be quickly recouped in reduced electricity bills, usually within the first or second year of use. A heat pump system will reduce your ongoing swimming pool heating costs by as much as 70%.

Combine your heat pump pool heating system with some Hi Temp HT50 Solar Panels, to harness some of the sun’s heat energy, along with a Salt Chlorinator and you are well on your way towards having an eco-friendly swimming pool.
