Baxi Boiler Review

Now part of the BDR Thermea Group, Baxi combines over 150 years of British engineering expertise with cutting-edge technology, producing efficient boilers that heat millions of UK homes. In 2025, Baxi’s combi boilers, including the 200, 400, 600, 800, Duo-tec, and Platinum ranges, are celebrated for their compact design, energy efficiency, and affordability, making them a top choice for homeowners seeking value-driven heating. Baxi combi boilers provide instant hot water and central heating from a single unit, eliminating the need for storage tanks, ideal for space-constrained homes like flats or medium-sized houses. Models like the 800 Combi 2 (25kW–36kW) offer A-rated efficiency of ~93%, with flow rates of ~10–15 liters per minute, suitable for 1–2 bathrooms. Featuring stainless steel heat exchangers and brass components, they ensure durability and low emissions. Ultra-compact (some as small as 700mm x 390mm x 290mm) and wall-mounted, they fit kitchen cupboards, with sleek aesthetics and Quiet Mark approval for minimal noise. Smart controls, like the uSense 2 app, enable remote operation, while features like EasyFill for pressure top-ups and 20% hydrogen-readiness enhance practicality. Installer-friendly with flue options up to 20 meters, they offer 3–10 year warranties, extendable with Gas Safe installation. Priced from £610–£1,600 (excluding installation), they’re cost-effective, though some Trustpilot reviews (4.5/5 from 5,000) note occasional delays in after-sales support. Best for small to medium homes, larger properties may require Baxi’s system boilers. With awards like Which? Best Buy for the 800 series and a focus on sustainability, Baxi remains a trusted, eco-conscious choice for efficient heating.
