GAR CREATES TURMOIL IN WATER HEATERS SECTOR
remove their water heating products from the UK market at short notice according to Lochinvar business development manager David Pepper. GAR is a safety regulation that applies to any product burning gaseous fuels and to components used in gas appliances. It replaced the Gas Appliances Directive (GAD) in April and includes a number of significant updates, not included in the old Directive, in a bid to improve safety standards across the EU.

The combination of this new regulation with the low NOx emissions standards about to be imposed by the Energy Related Products (ErP) Directive in September has forced several manufacturers to stop selling some of their atmospheric water heaters. Any appliance planned for production after April 21 this year must have a GAR certificate and all gas fittings must now be CE marked, including controls and other safety components. Many of the most widely sold ranges of water heaters no longer comply. Under the new rules, importers and distributors must also
prove that the products they handle comply with the Regulation. Under the GAD, responsibility for ensuring compliance rested solely with the manufacturer. A number of suppliers are struggling to adapt to the new requirements, but there are others, such as Lochinvar, who have made the changes needed. “The new rules are quickly and significantly changing the
marketplace for water heaters,” said Mr Pepper. “There is a danger that some end users will be caught out by this – particularly if they need an emergency replacement unit. He said that, in the longer term, the market would convert to condensing-only systems to meet the energy efficiency and low emissions targets imposed by the ErP. However, it was not always practical or cost-effective for many end users to do this now because of the system alterations – including new flues – that may be required when moving from traditional atmospheric technology to condensing. “Most water heater replacements are distress purchases, which means that the primary, and sometimes only, concern for many end users is to get the building’s hot water supply up and running again as quickly as possible,” said Mr Pepper. “The market is, generally, ready for the changes that the ErP will bring later this year, but the new safety rules imposed by the GAR have forced a number of manufacturers to remove products from the market earlier than anticipated. “To owners of restaurants, hotels, leisure centres and care homes having no hot water available is an alarming prospect, which is why the quickest fix is often the preferred solution. “

arrier in the UK launched its new AquaForce Vision 30KAV chiller at Twickenham Stadium. As well as learning more about the energy- efficient AquaForce Vision, customers and contractors had a chance to meet international rugby stars – former England captain Will Carling, Welsh captain Scott Quinnell and former England player and television celebrity Ben Cohen. Carrier, a specialist in high-technology heating, air conditioning and refrigeration solutions, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. The first phase of the new 30KAV range of variable-speed screw chillers, equipped with Greenspeed intelligence, covers cooling capacities from 500kW up to 1100kW, achieving significant levels of seasonal efficiency. Equipped with variable-speed screw compressors and variable-speed fans

– alternating current (AC) as standard and electronically commutated (EC) as an option – as well as optional variable-speed pumps, Carrier’s AquaForce Vision 30KAV automatically adjusts the cooling capacity and water flow to perfectly match the needs of the building or process load variations. The result is optimal operation at both full load and part load. This new
range of chillers has a SEER of up to 5.5 in cooling mode, and an Energy Efficiency Ratio (EER) of up to 3.49 at full load. 30KAV offers energy efficiency up to 40% higher than the 30GX range with the same footprint. “Our engineers have developed state-of-the-art technologies to exceed
the European Ecodesign energy performance standards by 30%,” said William Doll, product manager, Carrier, HVAC Europe. “AquaForce Vision 30KAV sets a new benchmark for efficiency, compactness and intelligence.” Operating at external temperatures ranging from -20°C up to 55°C and
negative water temperatures, 30KAV is an ideal solution for a wide range of sectors. From large-scale office buildings, hotels and healthcare facilities to data centres and industrial projects, 30KAV meets the most demanding expectations in terms of energy efficiency and savings, whatever the climate. The AquaForce Vision 30KAV introduces the latest Carrier technologies: - the new 06Z variable-speed screw compressor - the 6th generation Flying Bird Fan with EC motor - the 3rd generation Novation micro channel heat exchangers with a
unique W coil design built in one single piece The AquaForce Vision 30KAV also features Touch Pilot control with a colour touchscreen user interface in 10 languages and functions, such as Carrier’s smart energy monitoring to provide customers with smart data and optimise energy savings under real conditions. Furthermore, the 30KAV can be connected to Carrier’s remote monitoring centres where Carrier engineers can analyse data and optimise chiller performance. With sound levels of only 90dB(A) during operation, this new range has particularly low sound levels compared to its previous generation. The AquaForce Vision PUREtec 30KAV-ZE version, designed exclusively
for ultra-low global warming potential (GWP) refrigerant HFO R-1234ze, will be available in later this year. The range will also be extended up to 1,800kW cooling capacity with
premium technologies and additional options. Presenting the range to leading UK consultants and contractors, Nancy Jonsson, Carrier’s UK sales director, said: “We believe the new chiller is ideally suited to meet UK requirements, delivering outstanding energy efficiency across the range. The coming introduction of a HFO version later this year adds a further exciting option for end users keen to future-proof their buildings and achieve the highest environmental standards.”
