Ring us on 01732 748041 or e-mail twood@unity-media.com Smarter use of hot water heating a must A low carbon future across the complete built environment can only be achieved if the manufacturing industry meets its responsibilities to assist and wholly support this aim, says Rinnai UK’s Chris Goggin... Chris Goggin fears a lack of wholesale adoption of high efficiency technologies across the complete built environment where hot water generation is concerned. “There are some attempts to sidestep the very real need for the holistic adoption of high energy efficiency options,” he said. “Despite the widespread acceptance that the battle for a low carbon future lies in existing buildings, the legislators supported by industry have contrived to ensure that within the direct fired water heating section of Part L, there are proposals for the implementation of much higher product efficiencies for new build only.” It was only last year that the Department for Communities and Local Government proposed that all direct fired water heaters would have to produce minimum gross efficiencies of 90% for natural gas and 92% for LPG for new and existing buildings. This was later retracted after discussions with some parts of the industry when it was concluded that this wasn’t the best way forward. “The separation of new and existing building requirements for efficiency thresholds was agreed by some, but by no means all,” said Chris. “This is a missed opportunity by government as it would have also provided the ideal platform to counteract one of the key weaknesses of Part L - reducing installers opting for the cheapest first option or like for like replacement. Instead, we are maintaining a lower energy efficiency efficient appliance market.” Chris continued: “In the CIBSE president’s annual address, George Adams stated that ‘the environmental and energy impacts of the existing building stock remain a huge challenge’. This is an area where the adoption of energy efficient continuous flow gas water heaters in place of wasteful storage systems can have a positive effect on overall carbon reduction. “Do you leave your car running overnight just because you are going to use it in the morning? No. So why store large volumes of hot water just in case you might need it at some point when you can use energy only as and when you draw hot water? The fact is, we all need to be smarter about energy consumption.” Chris was speaking as Rinnai unveiled a number of new additions to its portfolio, including the Infinity range of continuous flow gas fired water heaters in heavy duty and condensing units, engineered to give high levels of efficiency and expansive ranges of modulation to maximise energy usage. Also new to the Rinnai range is the Infinity 16i gas fired continuous flow water heater, which is perfectly placed to meet the hot water needs of light commercial users, such as hairdressing salons, providing a constant flow of cost effective safe hot water with precision temperature control. Rinnai has also launched a common header flue system to streamline manifolded installations of its Infinity condensing continuous flow gas water heaters. Previously, multiple installation in an interior plant room would have meant each unit had to have its own flue and that meant punching a hole through the building fabric for each individual unit, a time consuming and expensive necessity. enquiry number 120 THE BRAND NEW SHOW FOR THE TRADE PROFESSIONAL & SPECIFIER AT THE RICOH ARENA, COVENTRY 28-30th October, 2014 EARLY BIRD DISCOUNT BOOK YOUR STAND BEFORE 31ST OCTOBER 2013 AND RECEIVE 10% OFF THE PRICE OF ALL PACKAGES www.btsshow.co.uk For more info or to book a stand please call Louise Opitz: Building trades & SPECIFIER
