On September 26, 2015, the latest Energy related Products (ErP) Ecodesign and Energy Labelling Directive relating to gas boilers came into force. Installers will be familiar with these requirements which are aimed at helping customers make the most energy efficient choices when purchasing a new heating system. They will also be aware that changes to the Directive are ongoing, with reviews in September 2016 to analyse the possibility of implementing requirements for different types of water heaters as well as in 2017, when second tier requirements regarding energy efficiency and updates to the Energy Labelling scheme will come into force. The next major change will be on September 26, 2018, when new requirements regarding the maximum threshold for NOx emissions come into force and Tier three requirements regarding the energy efficiency of water heaters start to apply. As with the introduction of the Energy Labelling Directive, manufacturers and their supplier partners are fully aware of how the NOx changes will affect the industry. Modern condensing gas boilers are already compliant with the NOx emissions changes as manufacturers have already done the majority of the work to ensure they are future-proofed. The key point to remember with regard to the NOx changes in 2018 is that although it’s part of the ErP Directive, NOx is not related to efficiency, it’s a measurement of exhaust gases. INSTALLER-CENTRIC APPROACH Installers were at the centre of thinking for manufacturers during the changes leading up to ErP and this fully designed and tested approach continues. For example at Ideal, during the preparations for the September 2015 directive, there were no changes to part numbers, ensuring no potential for confusion or error for installers on service calls. In addition, extensive field-trials were conducted on Ideal products over the winter, therefore, replicating ‘real-life’ conditions as much as possible. Any changes to parts, products and technologies were communicated directly to both merchants and installers. Manufacturers work closely alongside suppliers developing components, refining testing and applying the usual stringent reliability tests, thus ensuring any changes needed due to legislation or regulation do not WWW.HPMMAG.COM compromise boiler reliability. The same rigorous methods used during the preparations for recent changes will be employed throughout preparations for the NOx changes. At Ideal, the team is always looking to take the onus off installers through design, specification, production and quality testing. Rigorous attention to detail throughout the process removes the need for installers to make adjustments to components such as valves and reduces the impact of poorly installed flues. Continuous training and education of installers is closely aligned with ongoing design improvements. GAS IS KING The industry will continue to see the dominance of condensing gas boilers in new build housing, particularly in the UK where meeting energy efficiency targets and tackling fuel-poverty are key. Natural gas will continue to be ‘king’, but manufacturers will increasingly focus on what they can do alongside installers to add to efficiency through the addition of more sophisticated controls, as well as bringing solar thermal, solar PV and heat pumps into domestic systems where appropriate. 80 NOVEMBER 2015 HEATING & PLUMBING MONTHLY The NOx changes, while not directly related to energy efficiency, will help the UK meet its statutory commitment to reducing emissions by 80% by 2050. ON THE ROAD TO REDUCTIONS According to the European Environment Agency, NOx emissions decreased by 44% between 1990 and 2011. The recession and subsequent economic downtown that started mid-2008 was a key driver in the reduction between 2007 and 2011, primarily due to reductions in industrial and transport activities across Europe. Total emissions were reduced by 17% between these years compared to a seven per cent reduction in the years 2003-2007. The team at Ideal Boilers is always looking ahead in everything specified, in looking at regulation and market trends, in business improvement, in challenging reliability, in the design of experiments and changes brought by new technology. This is a process of continuous improvement, of marginal gains through incremental changes. QUICK GUIDE TO NOx NOx is a generic term for the mono-nitrogen oxides, nitric oxide (NO) and nitrogen dioxide (NO2). These are produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high temperatures. Nitrogen oxides are also produced naturally by lightning, and to a small extent, by microbial processes in soils. NO2 is a reddish-brown, highly reactive, hazardous gas emitted by road vehicles, shipping, power generation, industry and households. enquiry number 138 The NOx changes will help the UK meet its commitment to reduce emissions by 80% by 2050 The NOx logo
