Baxi 800: a mid-range combi with a straightforward reputation
The Baxi 800 range positions itself as a solid, no-frills mid-market combi, built by a manufacturer with one of the longest histories in UK domestic heating. It doesn't chase flagship features so much as reliable, serviceable basics.

Baxi's UK manufacturing heritage means parts availability is generally strong, and the 800 range's fault-code system is one engineers are broadly familiar with across the trade. It suits households who want a dependable name without paying for smart-home extras they may not use, though those features can usually be added via third-party controls if wanted later.
