What Heatrae Sadia does
Heatrae Sadia is a UK-based manufacturer of electric water heating, hot water, drinking water, and ventilation solutions, founded in 1929 in Norwich and operating today as a trading name of Baxi Heating UK Limited within the BDR Thermea Group. The company manufactures unvented cylinders (including the market-leading Megaflo sub-brand, which has become the generic UK term for unvented water heating), electric flow boilers (Electromax, Amptec at 99.8% efficiency), instantaneous and vented storage water heaters, wall-mounted boiling water dispensers (Supreme range with patented Intelliboil Plus smart controls), MVHR units, and Heat Interface Units for district heating. Core technology rests on proprietary engineering — a unique integral floating baffle expansion system in Megaflo cylinders, coil-in-coil heat exchangers for fast recovery times, marine-grade 2205 duplex stainless steel construction, and 60mm CFC/HCFC-free injected foam insulation — supported by ISO 50001, Kiwa, BEAB, WRAS, and HWA Charter certifications. The company serves UK residential and commercial/construction customers, hygiene-critical environments (hospitals, hotels, washrooms), and export markets (with a Doha representative office for the Middle East), distributing products through all leading UK merchants, a nationwide approved installer network trained and certified by the company, and direct consumer support for warranty and service. Revenue is generated through hardware sales of proprietary, branded products priced via merchant channels rather than public list pricing.
