here is a growing generation of fitness enthusiasts, with people ditching their cars in favour of cycling to work and swapping their
Saturday nights out for an evening in the gym. This has led to an explosion of new health clubs across the country, coupled with growing demand for showering facilities in offices. Dan Martindale, sales director at Andrews Water Heaters, explains how this increased need for water heating doesn’t have to come at the expense of energy efficiency. According to a report by Mintel, one in eight
(12%) of Brits now use health and fitness clubs, with the overall value of the market forecast to surpass £3 billion by 2018. Over half (52%) of those users visit the club at least three times per week, and those who go swimming are also more likely to also use wellness facilities (51%) or consume food and drink in the restaurant (35%). Meanwhile, in major cities, cycling to work has also seen considerable
valves, were custom designed to cope with the arid desert conditions in the UAE. The valves, manufactured in the UK, are a key element in the irrigation networks for major attractions including the Dubai Parks & Resorts integrated theme parks and the world class Dubai Opera in the Downtown Dubai opera district. The contractor, Delta Power Electrical, is also using Conex Bänninger industrial valves for the irrigation network that will supply water for landscaping around entrances, pathways and accommodation for Expo 2020, the world fair site being developed in four phases. Meanwhile, the company continues to be a regular exhibitor at major international shows, from MCE Asia, which has just taken place in Singapore to ISH in Germany, to the 2018 HVACR Show in London. Dan Wild, business unit director – UK & Ireland, said: “As part of the IBP group, Conex Bänninger has access to huge international resources, with world class manufacturing facilities, extensive research and development and the expertise of employees globally. “Combined with our commitment to innovative design, the
company is well set to continue its growth both here in the UK and on the global stage for years to come.”
growth. Between 2001 and 2011, the number of people living in London who cycled to work more than doubled from 77,000 to 155,000. A survey by the British Council for Offices also identified that 92.6% of respondents now think that showers are the most desirable workplace facility. What’s more, over half of the respondents said that the quality and availability of workplace cycle facilities influence their career decisions. The move towards a more active society has led forward thinking businesses to look at their employees’ welfare. Healthy and fit employees tend to be more productive and have fewer sick days, so there is a compelling commercial argument for encouraging an active lifestyle. However, if the heating system is incorrectly specified and operates inefficiently, the resulting rise in energy costs can impact on a business’s bottom line.
Installing a higher output boiler would help to accommodate greater demand for hot water. However, in modern buildings where the central heating can run at lower temperatures for a shorter time due to better insulation and lower heat losses, additional space heating is unlikely to be needed. A higher output boiler may therefore be oversized for a building’s overall heating requirements, resulting in energy wastage. One solution is to install a separate, dedicated water heater to cater for the hot water demand without wasting excess energy on heating. Separate space heating and hot water systems generally provide lower running costs, energy consumption and carbon emissions. This is because the water heater’s output can be more suitably matched to hot water energy load. On top of this, since water is heated from a low mains temperature (at a supply temperature of around 10 to 60˚C), high levels of condensing can be achieved, contributing to further savings. The heating system can also be switched off during summer months to reduce the electrical consumption from boilers, primary pumps and secondary pumps. To ensure that savings can be made, it is imperative that the water heating equipment is sized correctly. Too big and it will waste energy, too small and it will not produce enough hot water. Thankfully, the new and improved Size-it tool from Andrews Water Heaters provides assistance. Now available on any internet connected device, Size-it selects the most appropriate Andrews Water Heaters product for the job based on criteria input by the user. It is clear the fitness generation is here to stay, and higher demand for hot water doesn’t have to come at the expense of energy efficiency. Correctly sized and specified systems lead to facilities that are truly fit for purpose, and make smart business sense. For further information please visit
