Endless Solar Hot Water Sytems

How does an Endless Solar water heater work?
Most solar water heaters use flat plate technology which has been around for years. Endless Solar water heaters use state-of-the-art technology based on evacuated glass tubes and highly efficient heat transfer techniques.
Flat plate solar water heaters are only at their maximum efficiency in the middle of the day. A great deal of the Sun's energy is simply reflected off the flat glass panels, especially in the morning and afternoon.
Because the evacuated tubes in an Endless Solar water heater are cylindrical, they are always facing the Sun and can absorb more of the Sun's energy.
In fact, an Endless Solar collector will absorb up to 40% more of the Sun's energy that a comparably sized flat plate solar collector.
Yaktek Industries Tank Level Indicators
 
Levetator - Australia's most popular water tank gauge.
True Reading - Unlike homemade water level gauges that read back to front, the Levetator shows the actual water level. What you see is what you have.
Simplicity - No gimmicks, no batteries, just a simple float/weight/pulley system.

Dipstick
360° all-round visibility - This floating pole-type water level gauge, protruding above the tank roof, is the choice for many. It is ideal for "cup and saucer" tanks.
Highly Visible - High above the tank the level indicator can be seen from far away, in every direction, night or day.

Liquidator - Operating on the same principle as the Levetator, the Liquidator tank level indicator uses an external guide tube. The indicator slides up and down on the outside of the tube and the counterweight is contained inside it. Only the float is in contact with the liquid.

Everhard Industries
 
In terms of waste water disposal, Everhard Industries now offers consumers an alternative to the standard septic system. This alternative is called the 'Aqua-nova' system.
How does the Aqua-nova Aerated Wastewater Treatment System work?
Aqua-nova is a two tank system relying on a two stage digestion process using naturally occurring bacteria. In the primary stage of the process the bacteria are anaerobic, they must be starved of air. In the secondary stage the bacteria are aerobic, they colonise on a massive submerged media bed and must be supplied continuously with air (hence the two tank design).
At this stage the digestion process is complete. The effluent now passes via a clarifying chamber to the disinfection chamber where pathogenic bacteria are destroyed using a chlorination process.
Finally, a submerged pump with a level controller delivers the now clean, clear odourless and disinfected water through an irrigation system onto a landscaped garden. Nutrient uptake by plants and evapo-transpiration complete the total treatment process.
Many consumers are moving towards aerated wastewater treatment systems due to the multitude of benefits associated with owning one. Such benefits include:
- Save water - Reclaim all wastewater
- Environmentally friendly
- Easy to maintain
- Efficient and cost effective
- Council approved
- Safe and reliable

Rain Harvesting
The Downpipe Diverter is a simple and effective first flush device requiring minimal maintenance. Installed at the gutter downpipe or via a T-junction to a new or existing system of 90mm or 100mm diameter PVC downpipes. Add the appropriate length or pipe based on the quantity of water you wish to divert.
The Post/Wall Mounted Diverter is a versatile unit that can be mounted on a wall, post or stand to hold larger volumes. Can be adapted to suit a wide range of applications and will manage single or multiple pipes coming from the roof to divert between 20 and 150L. Includes a galvanised steel mounting bracket and saddle.
Filter Pits handle large volumes of rainwater and enable screening to be done at a central point in the system. In some cases they can be safer and easier to clean than rain heads fitted at roof gutters.

The Leaf Eater ® prevents gutters from blocking and eliminates a fire hazard by screening leaves onto the ground. The Leaf Eater ® is the ultimate high performance solution and was the first multi-screen rain head developed.
