Get solar hot water from ET Solar … and save!
Did you know that hot water can account for more than 30% of your household’s energy cost … and that a solar hot water system can reduce the average hot water bill by as much as 70%?
Replacing your old electric hot water system with an energy efficient solar hot water system is one of the most effective ways of not only reducing your carbon footprint … but also permanently reducing your energy bill.
The new evacuated tube solar hot water system from ET SOLAR is available in 300 or 400 litre capacities and suitable for all domestic and commercial applications.
All ET SOLAR solar hot water systems feature ...
- Stainless steel tank (squat or slimline models*)
- Three layer evacuated glass tubes
- Tempering valve
- Fully enclosed work station (housing controller
and pump) - Aluminium mounting frame
A comprehensive replacement warranty of between 2 and
15 years applies to all components.
The high performance pump from respected Danish manufacturer Grundfos, is standard equipment on all ET Solar hot water systems and carries a 2 year replacement warranty, compared to only 12 months on many competitive products. The controller also carries a 2 year replacement warranty.
The stainless steel tank carries a 10 year warranty. The tank is manufactured from long lasting 316 marine grade stainless steel … an infinitely better proposition than the glass lined enamel tanks offered by other manufacturers.
Finally, the evacuated tubes, the collector and the manifold* carry a 15 year warranty.
ET Solar systems are light weight (no need to strengthen roof trussing), suitable for installation on both pitched and flat roofing and are essentially maintenance free.
The system meets all category related Australian Standards, is rebate and Small Scale Technology Certificates (STCs) approved ... and all components are subject to an extensive quality control and testing procedure throughout both the manufacturing and assembly process, to ensure optimum performance for years to come.
How does the system work?
The collector is comprised of thirty or more (depending on the system’s capacity) exceptionally strong multi layered glass tubes. A vacuum exists between the inner and outer layers of each tube to ensure captured energy is retained.
The sun’s energy is absorbed by the array of evacuated tubes at an optimum level throughout the day. The surface of an absorptive material (copper, stainless steel and aluminium nitride) coated on the inside of the inner tube, absorbs maximum radiation and converts it into heat. The vacuum between the inner and outer tubes ensures minimal heat loss … with in excess of 90% of the sun’s available energy being captured. Each tube is connected directly into a multi-port manifold mounted at the head of the collector.
The intense heat is transferred into the manifold via innovative copper heat pipes located inside each tube. Water is then pumped through the manifold, heated and stored in the stainless steel water tank located at ground level.
To ensure the hot water is safe for use, cold water is mixed with hot water directly from the tank via a tempering value, to ensure a serviceable water temperature of 55 degrees Celsius is maintained.
Evacuated tube solar hot water systems are capable of harnessing the heat of the sun in all types of climatic conditions … offering excellent performance in all from overcast to extremely cold, even sub-zero environments.
Evacuated tube technology is extremely efficient, as the cylindrical configuration of the tubes enables the sun to always strike at the optimum angle … compared to flat panel systems which only perform at their best for a limited time through the middle of the day.
The evacuated tubes use a heat transfer process to convey captured energy to the collector. Water does not enter the tubes. Flat panel technology relies on the circulation of water through the actual panel and insulation areas, subjecting the panel to leakage, corrosion, even blockage.
The tubes are made of toughened glass and capable of withstanding hail stones in excess of 25mm in diameter (approximately the diameter of a golf ball). If a single tube or multiple tubes are broken, the system will not fail … it is a simple case, for a minimal outlay of replacing the broken tubes to restore the system to full capacity.
Having plenty of hot water in times of higher than normal consumption or during periods of adverse weather is important ... so ET Solar hot water systems are fitted with an electric boost element, that automatically activates during the nominated off-peak period to ensure an adequate supply of hot water is on-hand at all times.
What are the advantages of an evacuated tube solar hot water system?
- Excellent cold weather performance
- Passively track the sun … up to 80% more efficient than flat panel technology
- Lightweight …no need to strengthen roof trussing.
- Maintenance free
- Most comprehensive warranty on the market
- Flexible installation options
Installation … what are my options?
As a rule, a standard installation would be best described as a single storey dwelling, featuring a pitched roof, where the new water tank was positioned in the original location.
If the roof was flat or low in pitch, a tilt frame would be recommended to position the collector at approximately 30 degrees above horizontal.
For optimum performance, it is recommended that the collector be mounted on a north facing roof. An east or west facing installation is suitable, but heating is limited to the morning or afternoon, for an east or west facing roof respectively.
Electric hot water systems are being phased out … so it’s time to act!
An electric hot water system in an average domestic environment produces approximately four tonnes of greenhouse gases per annum … double the output of more energy efficient technologies such as solar.
Federal and State Government’s have implemented programs to phase out electric hot water systems over the next twelve months and considering the spiralling cost of electricity ... there has never been a better time to upgrade to a more energy efficient hot water system for the home.
