Baxi is an East Midlands-based boiler brand. It was founded in 1866 by ironmoulder Richard Baxendale and his partner Joseph Heald. It's now part of BDR Thermea, which also includes the boiler brands Potterton and Main, and is one of the largest boiler manufacturers in Europe.

Baxi offers several combi boiler ranges, including Baxi Ecoblue, Baxi Platinum HE A combi boilers, Baxi Duo-tec GA combi boilers and Neta-tec GA combi-boilers. It also produces the Baxi Solo heat-only boiler range, the Baxi Bermuda back boiler range, and the Baxi Megaflo compact system GA boiler range.
