Filling the 3 Star Hole

As of 2 May 2013, the Greenhouse and Energy Minimum Standards (GEMS) have determined that all outdoor gas water heaters manufactured or imported into Australia must now have a Minimum Energy Performance Standard (MEPS) of 4 stars. So what does this mean for plumbers and homeowners?

Although the ban will result in a slightly higher upfront cost, there is an obvious running cost benefit in moving to a more efficient heater.

For those wanting to make the move with the least amount of hassle, Dux offers both the Prodigy 4 and Prodigy 5 star water heater ranges that conveniently come in the same sizes (135L & 170L), footprints (422mm x 502mm) and plumbing configurations (dual handed and same heights) as the Prodigy 3 range. Table 1 below summarises the ranges.

In an Australian first, the Prodigy 5 has the same footprint (422W x 502D) as existing rectangular 3 star external gas units, facilitating easy replacement of old 3 star systems. In another Australian first, the Dux Prodigy 5 also uses a patented ‘flue damper’ design to deliver high efficiency whilst retaining the traditional compact gas storage tank design.

It is important to note that despite the manufacture cut off date, any existing 3 star gas storage stock can continue to be installed while stocks last.

For those wanting to step up to the ultimate in energy saving water heating methods, gas boosted solar is the way to go. The recently released Dux Sunpro MP15 gas solar hot water heater fills a gap in the market, by providing mains pressure hot water whilst typically not requiring a gas line upgrade (unlike traditional Continuous Flow Boosted models). This makes it ideal for replacing traditional gas storage water heaters.

The Sunpro MP15 also has a number of other key features that set it apart from its competitors. The pre boost feature, heats water in the top of the tank before its needed and eradicates water wastage at the beginning of the cycle. This has been coupled with the brand new panel management system which drains the panels in cold weather ensuring outstanding frost protection in winter.

Whether seeking a higher efficiency gas storage tank or a gas boosted solar system, Dux has you covered. Dux also remains the only hot water brand that is both part of an Australian owned company and also manufactures tanks in Australia.
