Solar radiation is the heat, light and other radiation that is emitted from the sun. Solar radiation contains huge amounts of energy and is responsible for almost all the natural processes on earth. The suns energy, although plentiful, has been hard to directly harness until recently.
By installing a solar water heating system, a typical household can meet 60 to 95 percent of their hot water needs. And though they cost a little bit more up front to install, the system will save you money in the long run as the fuel source (the sun’s energy) will always be free. |

| With regular inspection, the system will operate for 20 to 30 years with minimal maintenance and costs. Flat plate thermal solar collectors have been in use for several decades, but only in relatively small numbers, particularly in Western countries. |
| Evacuated tubes have also been in use for more than 20 years, but have been much more expensive than flat plate. In recent years the production volume of evacuated tubes has exploded, resulting in greatly lower manufacturing and material costs. The result is that evacuated tubes are now similar in price to flat plate, but with the insulating benefits of the evacuated tube and its ability to receive the sun's rays from longer angles. These systems are 40% more efficient than the conventional flat panel system and are set to become the default choice for thermal solar applications worldwide for homes, villas, hotel resorts and all commercial businesses. |

| In the average household, water heating accounts for around 30% of CO2 emissions. By installing a solar water heater, which can provide between 60-95% of your hot water heating energy needs, you can reduce your total CO2 emissions by more than 25%. Using solar and other forms of renewable energy reduces reliance on fossil fuels for energy production, thus directly reducing CO2 emissions. CO2 emissions contribute to global warming, an environmental issue which is now of great concern. |

• Hot Water from Air Conditioners |
Free Hot Water from Air-conditioning Waste Heat
In hot climates a proven strategy that works well is a heat recovery unit attached to your AC unit. It provides free hot water and increases the efficiency of the AC by reducing head pressure (and electricity draw) on the compressor. You're paying for your AC to move a great deal of heat out of your house this is the heat that is currently blown into the atmosphere by the AC system's condensing unit you might as well use that heat to provide you with hot water. Adding one of these to an AC unit is a good way to lower your monthly power bill.
The great thing about the solution is that it's costnegative. In addition to being free hot water as opposed to other "high efficiency" heaters that still consume energy, it actually lowers your cost of air conditioning ! |
• Sizes from 50L to 350L storage tanks
• Mounting type: vertical / horizontal
• Can connect up to two separate air conditioning units
• Can also be connected to a solar hot water collector for greater versatility
• Computer controlled electric element
• Can be programmed for time and temperature

This is exactly what Enviro-Pak is for. Recycle the waste heat released from the AC, make hot waterand save money. You pay the electric company to run your AC to remove the heat from your house and send it outdoors.
At the same time, you are paying the electric company to make hot water for your shower, laundry and dishwasher.
Heat Recovery Units takes heat and turns it into hot water. The air conditioner or heat pump works hard on hot days. It removes the heat from inside your home and sends it to the outside. At the same time the water heater in your house is working hard to heat the water for the shower, laundry, and dishwasher.
Enviro-Pak can also be installed when the AC is serviced for a change out. Enviro-Pak can cut water heating costs by up to 50%. Also, because the AC compressor doesn't have to work as hard, the AC system draws less power, and the work load is reduced. Your AC runs more efficiently and can save you up to 15% on cooling costs.
