Queen’s Award for Andrews Water Heaters
Outstanding innovation in energy-efficiency high-performance production of domestic hot water has won a Queen’s Award for Andrews Water Heaters
Andrews Water Heaters has won a Queen’s Award for Enterprise for the development of the MAXxflo stainless-steel condensing commercial storage water heater. This was the first product of its kind on the UK market and was judged to be ‘an outstanding innovation in energy-efficient high-performance production of volume hot water for large residential, commercial and industrial applications. Its highly efficient heat exchanger, special burners and tank design enable high performance, low energy consumption and low running costs to be combined with low carbon-dioxide and nitrogen-oxide emissions. In addition, it has an anti-legionella feature which contributes to improved health and safety.’ Paul Hardy, managing director of Andrews Water Heaters, is delighted at winning the award. He says, ‘MAXxflo is a truly exciting development for the sector, which brings water-heating technology right up to date. Although not the first storage water heater to adopt a condensing principle, it utilises innovative condensing technology with the primary return to the burner module coming from the bottom of the tank. This allows up to 80% of the tank volume to be heated in condensing mode, which had not before been achieved in a production model. The resulting net efficiency is a high 109% with extremely low NOx emissions figures of 25 ppm.’
