On the tools

Assure runs alongside Baxi's numbered ranges as the brand's installer-focused line, rather than sitting directly above or below the 800 and 600 on a single ladder. Because it spans combi, system and regular, it is a broad, flexible choice across mixed workloads.

Variants and configuration

Covering combi, system and regular (heat-only) formats, Assure has one of the widest configuration spreads of any Baxi range covered here. Warranty and features vary by individual model, so check Baxi's current line-up and the data plate rather than assuming from the Assure name alone.

Where it sits in the range

Rather than sitting on the same ladder as the 800 and 600, Assure runs as a parallel range from Baxi aimed at giving fitters a broad spread of combi, system and regular options under one warranty and support offering.

Finding the manual and the data plate

For the exact outputs, gas rate, dimensions and commissioning figures, work from the appliance’s data plate and the manufacturer’s installation and servicing instructions. The GC (Gas Council) number and serial are on the data plate, usually behind the front panel or on the underside. Baxipublishes its manuals and support at Baxi support.
