3 Why Andrews Water Heaters? 3 Andrews Water Heaters, part of Baxi Commercial Division, is the UK s market leader for the supply of high efficiency direct gas-fired commercial water heaters, having the broadest portfolio of products and the largest selection of models in the condensing water heating sector alone. Established in 1976, Andrews Water Heaters remains the No. 1 provider of cost effective water heating solutions in a wide variety of multiple large residential, commercial and industrial properties. The full range of water heaters comprises of twelve models with recovery rates from 178 litres per hour to 9,200 litres per hour, ranging from 9.5 kw to 550 kw. These models offer different types of water heater options, from standard atmospheric to fully premix condensing, with flue options such as open flue, fan assisted, balanced flue and room sealed available. The basic design principles of these units offer high energy efficient operation, which has been successfully exploited in a number of award winning energy conservation projects (please see the Andrews Water Heaters website for full details and numerous case studies). These principles have been further developed to meet changing environmental concerns and legislation. All models carry the European Standards EC mark and the Queen s Award winning MAXXflo is included in the Government s ECA scheme, as well as the NEOflo, ECOflo and SUPAflo. Full details of our Size IT Guide, please visit our website, Andrews Water Heaters also offer a complete range of LZC solutions, including solar thermal packages and air source heat pumps, which can be utilised alongside high efficiency water heaters to minimise energy use and significantly reduce carbon emissions within commercial buildings. For further details on all Baxi Commercial Divisions low to zero carbon range please consult the LZC Technology Guide available from the website. Sales: Technical:

The Centre, for people with sight loss, brings together services which were previously housed in eight separate buildings on the seven acre site. The new state-of-the-art facility comprises athree storey office block and a separate support area tothe residential block, which have both been designed to achieve an energy efficient solution which minimises CO 2 emissions. The whole building concept scheme with the twosolarflo systems wasspecified by Rediger Ltd., who are CIBSE registered LowCarbon Consultants. Aspokesman commented, We haveused the equipment in the pastand Andrewshave a good reputation in thisrespect.
