Sunpro® 305 Gas Boosted Solar Hot Water
 |
 |
The Sunpro® 305 gas boosted solar takes hot water efficiency to the next level with the patented Hotlogic® processor that minimises energy waste like no other solar hot water system. It’s no wonder the Australian Greenhouse Office calls gas boosted solar the most environmentally friendly domestic hot water solution available.
How does it work?
Just like a traditional hot water system, cold water enters the Dux Sunpro® solar storage tank. The patented Hotlogic® processor transfers this cold water from the tank up to the highly efficient solar collectors. These collectors have a highly absorbent black chrome selective surface coating to ensure exceptional heat transfer.
As the water is pumped through the solar collectors, the sun’s energy is absorbed by the collectors and transferred to the water, heating it naturally as it passes through.
The Hotlogic® processor is constantly watching the changing weather conditions and transferring water through the collectors until the tank reaches its designated temperature (or until the temperature differential is too low, like on cloudy days).
Now on cloudy days, the Hotlogic® processor recognises the reduced solar gain and automatically boosts the tank with environmentally friendly natural gas. The Hotlogic® processor optimises the hot water temperature in the tank to the normal delivered hot water temperature to minimise any energy waste.
This ‘next generation’ intelligent technology searches for and switches to the cheapest available energy source automatically.

Sunpro® Gas Continuous Solar Hot Water

The Sunpro® Gas Continuous boosted solar hot water system is the ultimate in environmental hot water. It’s no wonder that the Australian Greenhouse Office calls gas boosted solar the most environmentally friendly domestic hot water solution available.
How does it work?
Just like a traditional hot water system, cold water enters the Sunpro® solar storage tank. The patented Hotlogic® processor transfers this cold water from the tank up to the highly efficient solar collectors. These collectors have a highly absorbent black chrome selective surface coating to ensure exceptional heat transfer.

The Hotlogic® processor is constantly watching the changing weather conditions and transferring water through the collectors until the tank reaches its designated temperature (or until the temperature differential is too low, like on cloudy days)
At this point, Hotlogic® switches off and waits for you to enjoy your naturally heated hot water. The heavily insulated Sunpro® solar storage tank is designed to keep the water warmer for longer, just like a thermos.
Now on cloudy days, the continuous gas unit recognises the reduced hot water temperature and automatically boosts the hot water with environmentally friendly gas to the desired temperature.
It’s the patented Hotlogic® processor combined with the highly efficient solar collectors and heavily insulated tanks that makes the Sunpro® Gas Continuous boosted solar the ultimate choice in environmental hot water.

Sunpro® Electric Boosted Solar Hot Water
 |
|
The Dux Sunpro® electric boosted solar hot water system is pound for pound one of the most efficient electric boosted solar hot water systems in its class. It’s reassuring to know that the Dux Sunpro® electric boosted solar hot water system is generally 10% more efficient than same (or similar) sized systems in its class
How does it work?
Just like a traditional hot water system, cold water enters the Sunpro® solar storage tank. The patented Hotlogic™ processor transfers this cold water from the tank up to the highly efficient solar collectors. These collectors have a highly absorbent black chrome selective surface coating and ultrasonic welding to ensure the highest efficiency within its class.
As the water is pumped through the solar collectors, the sun’s energy is absorbed by the collectors and transferred to the water, heating it naturally as it passes through.
The Hotlogic® processor is constantly watching the changing weather conditions and transferring water through the collectors until the tank reaches its designated temperature (or until the temperature differential is too low, like on cloudy days).

Now on cloudy days, the Hotlogic® processor recognises the reduced solar gain and automatically boosts the tank with ‘back up’ electricity. This ‘next generation’ intelligent technology searches for and switches to the cheapest available energy source automatically.

Airoheat® Heat Pump – solar hot water without panels
 |
|
The Dux Airoheat® heat pump is a technology breakthrough that provides all of the benefits of environmentally friendly hot water without the need for solar collectors.
In fact, the Dux Airoheat® heat pump hot water system was recently awarded the 2008 Australian International Design Mark, further testament to its remarkable innovation. The Airoheat® heat pump is the only domestic hot water system to be awarded such a prestigious accolade.
How does it work?
The principle of heat pumps is very similar to that of your fridge, except that it is in reverse. The Dux Airoheat® heat pump contains a fan that sucks air through an evaporator. The evaporator contains extremely cold liquid refrigerant, which travels through a copper pipe. The air passing through this evaporator contains latent heat energy which is absorbed by the refrigerant. A compressor then pulls the refrigerant inside where it is naturally compressed.
As the pressure rises, the temperature increases. From here the refrigerant travels to the condenser, where the heat from the refrigerant is transferred to the water through a water immersed coil, exclusive to the Airoheat® heat pump.

Prodigy® 5 Star Gas Storage
The Dux Prodigy® 5 Star gas storage hot water system is one of the most efficient hot water solutions available, particularly when it isn't possible to install a solar hot water system.
The Prodigy® 5 Star gas storage hot water system is ideal for larger homes, where hot water demand is higher and more frequent.
How does it work?
The Prodigy® 5 unit is more than just a standard gas storage system. It works off a high performance, internal gas burner which has been combined with very efficient insulation to give the unit its 5 star efficiency rating, thereby minimising running costs.
The Prodigy® 5 system is available in 2 models - 330T & 360T which have internal tank sizes of 135L and 170L respectively. At times where demand is high the unit can recover at a rate of almost 200L of hot water per hour (temperature rise of 45C and inlet temperature at 15C, running off natural gas). This means you have plenty of hot water when you need it most.
Because the Prodigy® 5 is a storage system, it has the added benefit of being able to provide mains pressure hot water to your taps. This means multiple fixtures can run at the same time without a drop in flow or temperature (a problem sometimes associated with continuous flow hot water systems).
Aesthetics are not something normally associated with a hot water system, but the Prodigy® 5 is different. It has been designed to look more like a modern appliance, which means a more stylish look to your home. The Prodigy® 5 also comes with a 10 year warranty on the tank and is available in both Natural Gas and LPG models.

Endurance® 5 Star Continuous Flow
The Dux Endurance® continuous flow gas hot water system offers precise temperature control with the added benefits of unlimited hot water. Whilst not a solar or heat pump hot water system, the Endurance® continuous flow unit still offers users environmentally friendly hot water.
How does it work?
As the hot water tap is turned on, cold water enters the continuous flow water heater. The water flow sensor immediately detects the water flow. The computer processor automatically ignites the burner and circulating water moves through the heat exchanger constantly gaining heat until it reaches the designated temperature.
When the tap is turned off, the water flow sensor shuts the unit down.
