What Andrews Water Heaters does

Andrews Water Heaters, trading as Andrews Water Heaters by Baxi, is a UK-based brand specialising in gas-fired commercial water heating solutions. The product portfolio encompasses non-condensing water heaters (CLASSICflo, CLASSICflo BALANCED, CLASSICflo FAN FUELED, HIflo EVO) for applications where regulations permit, and high-efficiency condensing water heaters (COMBIflo, ECOflo, ECOflo COMPACT, MAXXflo EVO, MAXXflo EVO Lite, SUPAflo EVO 2) for decarbonisation-driven demand. Supporting accessories include buffer tanks (BUFFER GL-8, BUFFER GL-10), stainless steel storage cylinders (STOR SS, STXL Cylinder), hot water storage buffers (HWST), and FLEXIstor flexible storage systems. The brand sells into four primary commercial verticals: education, healthcare and care homes, hotels and leisure, and defence and justice estates.

The business operates as a trading division of Baxi Heating UK Limited (registered in England and Wales, company number 3879156), itself a subsidiary of the international BDR Thermea Group. The company does not publicly price its products; instead, Technical Sales Managers engage directly with commercial customers for quotations, sizing assistance, and technical support, while commissioning and warranty activation are handled through a network of Baxi Approved Service Agents. A 2-year parts and labour warranty attaches to commissioned products (12 months otherwise), and spare parts are supplied via a PartsArena database with next-day delivery through nationwide stockists; products are supported for at least 10 years after discontinuation.

The brand's competitive positioning rests on its heritage as part of Baxi (manufacturing in the UK since 1866), active membership in CIBSE, SoPHE, and ICOM standards-setting bodies, and the provision of BIM Level 2 and CAD design libraries to specifiers. Free professional training is delivered at the Warwick Centre of Excellence and Dartford Solutions Academy. In 2026, the Andrews Water Heaters website was transitioned to direct users to Baxi's Commercial Heating and Hot Water Solutions section, consolidating the digital front door while the Andrews product line continues to be marketed as a distinct commercial offering within the Baxi portfolio.
