Client Feature PRODUCT Innovation BCA & INDUSTRY NEWS Bosch sets new benchmark in sustainable water heating Creating a new benchmark in sustainable, energy efficient water heating, is the new ‘Bosch 32C Commercial Condensing’ gas hot water system, positioned as the only one of its kind in Australia. Suitable for both commercial and domestic use, where there is demand for large volumes of hot water, the Bosch 32C boasts a 6-star energy rating, making it the most efficient commercial gas hot water unit on the market. The product’s edge is its unique ‘condensing technology’, which creates a superior level of energy efficiency – more than 94%. Unlike traditional hot water systems, Bosch’s condensing technology captures waste heat from exhaust gas and uses it to preheat incoming cold water. The effect is an energy saving of more than 15.5%, compared to a standard continuous flow commercial system. Bosch National Commercial Manager, James Smith, said the environmental benefits of the Bosch 32C made it far superior to any other commercial model available, setting a new benchmark for the industry. “Choosing this system for a commercial project is the equivalent of taking one and half cars off the road for an entire year, saving tonnes of greenhouse gas emissions and major dollars in terms of running costs*.” He said the new product gave builders, architects, hydraulic consultants and plumbers the opportunity to meet and exceed the Australian Building Code Board’s latest energy efficiency provisions, while reducing environmental impact and energy costs for their clients. Designed specifically for commercial developments and large homes, the Bosch 32C (along with the 32 standard model) is the only true commercial unit on the market and the only continuous flow system able to be installed internally or externally. “The unit has dual heat exchangers, one for primary heating and one for secondary heating. A 100% stainless steel exchanger uses residual heat from exhaust gases to help preheat incoming water prior to it entering a primary copper heat exchanger,” Mr Smith said. “The copper heat exchanger is coated to prevent corrosion and deterioration, and the internal copper piping is 25% thicker than any other model,” he said. Features & Benefits • 6-star energy efficiency rating – the most efficient commercial gas hot water appliance on the market, with 94% energy efficiency. • 217 MJ/hr gas consumption, producing a flow rate of 32 litres per minute. • Designed to run up to 16 to 20 hours per day. • Only commercial continuous flow unit on the market that can be installed internally or externally. • 25% thicker commercial-grade copper heat exchanger, fused with 100% stainless steel corrosionresistant heat exchanger. • Commercial-grade components throughout, including heavy duty resin-coated printed circuit board, increases durability and protection from the elements. • Can be installed as a single unit, manifolded or in combination, with storage. Self-diagnostic electronic staging and rotation system (in manifold). • In-built neutraliser for the safe release of condensate (pH-neutral condensate). • Optional temperature controllers (up to three), offering fingertip water temperature control. • Available in 37°C to 85°C temperature range (without temperature controllers), 37°C to 80°C temperature range (with temperature controllers), or 50°C locked. • Compatible with solar hot water and warm water return systems**. • Premium warranty – two years on parts and labour and five years on the heat exchanger (or three and 10 years when used in domestic applications). The Bosch 32C was developed in line with Australia’s Ecologically Sustainable Development (ESD) standards, and to complement Bosch’s existing range of energy efficient products. The domestic condensing model, the Bosch 26eco+, with a 6.9-star energy rating, was recently named the GreenPlumbers ‘Product of the Year’ (2009), demonstrating the superior ecological benefits of the Bosch condensing range. The Bosch 32C is available from local plumbing suppliers or by contacting the Bosch Customer Service Hotline on 1300 30 70 37.

Philips Innovation: the MASTER TL5 Eco Philips most recent energy saving innovation is the MASTER TL5 Eco. This unique range reduces energy consumption by 10% without reducing lighting quality. These savings are made possible by the unique mix of filling gases and new phosphor technology which improves lighting output while reducing energy consumption. The MASTER TL5 Eco 25W lamps are a direct replacement for a regular TL5 28W and in the application provides the same light output - 2900 lumens. The benefit of a true retrofit solution is the ease of use. MASTER TL5 Eco lamps are designed to work in all the applications that currently use the conventional TL5 lamps and therefore make them perfect for relamping existing TL5 luminaires as well as new buildings and renovations. But energy saving isn’t the only benefit of MASTER TL5 Eco. All of the existing specifications that have made Philips TL5 a popular choice have been included in this new technology : low mercury, (1.4mg), long lifetime, high CRI and ability to be dimmed, mean that this unique range can be included in almost all applications where TL5 is specified. Philips now offers a range of TL5 Eco lamps that will offer energy saving options for most current TL5 applications. We see this as a major step towards making energy saving easy to experience for all customers, while not compromising on lighting quality.

Are you using products that comply? It is your responsibility to ensure your window manufacturer has compliance to AS 2047 or it will end up costing the builder or the owner a lot of money. Don’t take any chances! All AWA members undergo performance tests to verify performance claims. What is AS 2047? It is the mandatory minimum specification for windows and doors used in Australia it includes compliance to the Glass Standard AS 1288. The following performance tests are undertaken to verify product performance claims. 1. AS 4420.2 Deflection Test – positive and negative wind pressures are applied to the face of the window to test the maximum deflection under wind load. 2. AS 4420.3 Operating Force Test – to verify that an opening sash is capable of opening and closing without undue effort. 3. AS 4420.4 Air Infiltration Test – the air leakage of a window is tested to ensure energy and acoustic efficiency. 4. AS 4420.5 Water Penetration Resistance Test – this test is designed to ensure no water leaks through the window into the building. 5. AS 4420.6 Ultimate Strength Test – negative and positive wind pressures are applied to the window to at least 1.5 times the design wind pressure to ensure it does not fail in unusual wind conditions. All windows and doors for homes must have a Performance Label which confirms that they are certified to comply with Australian Standard AS 2047. If you purchase windows from an accredited AWA member, you can also receive a Certificate of Compliance that supports a 7 year warranty. Example: Window label which should be affixed to window and door products to ensure compliance to AS 2047. All AWA members have products tested to AS 2047 and are a part of a third party NATA accredited program. This accreditation program is a proven and nationally recognised method of achieving compliance to assist builders, specifiers and homeowners to select products that comply with Australian Standards. Look for these logos when purchasing your windows to be confidant you are purchasing compliant products. Please visit www. awa.org.au for more information Australian Building Regulation Bulletin • 31
