BSEE INDUSTRY UPDATE
The new Gas Appliance Regulaon (GAR) has forced some manufacturers to remove water heang products from the UK market at short noce. And according to Lochinvar’s David Pepper, the new rules are quickly and significantly changing the marketplace for water heaters.
AR 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 the boiler, water heater and heat pump manufacturer Lochinvar said it had already made the changes needed to its products.
“The new rules are quickly and significantly changing the marketplace for water heaters,” said Lochinvar’s Business Development Manager, David Pepper. “There is a danger that some

end users will be caught out by this – particularly if they need an emergency replacement unit.
“However, at Lochinvar, we had been preparing for these changes for some time and so all of our atmospheric water heaters are already GAR- certified. This means we can continue to meet our customers’ requirements without interruption.
“We took this step and made the investment in testing because we anticipated that there could be a sudden shortage in the market that might leave some customers exposed,” added Mr Pepper.
Condensingonly systems
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 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, care homes etc, having no hot water available is an alarming prospect, which is why the quickest fix is often the preferred solution. Fortunately, Lochinvar can still supply compatible replacement products directly from stock and often within 24 hours.”

Venlaon constutes 30 per cent of a building’s total energy consumpon. Invesng in a venlaon system using new ultrasound technology will cut operang costs and help reach the EU’s target of reducing energy consumpon by 20 per cent by 2020.
f we are to limit human impact on the Earth’s climate, several things need to be done. In 2007, EU leaders agreed on a set of goals. One of these was to reduce energy consumption in the member states by 20 per cent by the year 2020.

The increased focus on climate has inspired companies and industries to start developing new solutions that will help reach the targets.
A revoluon in the venlaon industry
In 2015, development began on a new technology for measuring air flow and temperature in ventilation systems. It uses ultrasound sensors to provide a very accurate measurement of the entire airflow area without causing extra pressure loss in a ventilation system. Since the technology is based on ultrasound sensors there are no obstacles in the air stream on which dirt can gather. This means uninterrupted airflow without extra pressure loss, offering unique benefits in terms of energy efficiency, simplicity and cleaning.
Needless to say, the technology application revolutionised the ventilation industry at the time.
Changing the rules once again
During the last couple of years, an increased focus on energy savings in our industry has made demand control ventilation systems with low volume flows increasingly common. This in turn increases the need for measuring devices and methods with even higher accuracy in low volume flow conditions.

uInvesng in a venlaon system using new ultrasound technology, such as Lindab’s UltraLink, will cut operang costs and reduce energy consumpon.
“Large pressure loss in ventilation systems and difficulties measuring air flow with high accuracy in low air velocities has been a big problem for a long time, resulting in unnecessary high energy consumption and high operating costs,” says Torbjörn Bruzelius, Strategic Product Manager for Lindab Group.
Building contractors and property developers are increasingly requesting new ways to optimise and modernise ventilation systems. Lindab has improved its UltraLink technology to take precise measuring of air flows one step further. In the new and improved version, both measuring equipment and dampers are integrated into one solution, which now has wireless Bluetooth connection capability.
Fewer parts, less cabling and better connectivity simplifies ventilation system control. Being able to monitor and adjust air flow with high accuracy and ease saves time, energy and money. By developing new solutions and introducing innovations to the market we can do our share to reduce energy consumption.
