With its origins stemming all the way back to 1866, it’s fair to say Baxi is a company that knows a thing or two about the heating industry.

Today, Baxi is a brand internationally recognized and trusted, who’s continued innovation, design and engineering further their aims of providing affordable, efficient heating for the masses.

Typically, a Baxi Platinum combi boiler will cost around £200 less than a similar Worcester Bosch equivalent.

This means that you can save up to 80% on installation costs by installing one of these heaters! In addition- depending upon your needs and requirements for different features there may be even more value in choosing this product over another brand which could end costing significantly higher during purchase but also provide reduced functionality when compared with what's offered here at first glance (Worcester).

Baxi Platinum Combi Key Features

Quality Components

The Baxi Platinum combi contains several function aiding and efficiency boosting components, these include - a frost thermostat, high performance brass hydraulics, internal mechanical clock and filling loop.

This premium boiler also comes with a pre plumbing jig and a pre formed copper pipe tail.

Smart Technology

The 800 can be easily controlled by the brands uSense smart thermostat control system, also the 800 can be synced up with a control app, meaning you can regulate your boiler’s functions remotely on a smartphone or tablet at the tap of a button.

Can also be combined with Baxi’s multifit IFOS (in flue outdoor system) for added weather compensation functionality.

Powerful Flow Rate

For each of its kW sizes the platinum combi has a strong water flow rate, especially in its largest 40kW variant with 16.4 litres of water per minute produced. 

A good flow rate means hot water is readily available faster, reducing frustrating waiting times while also reducing wasted expensive energy.


Baxi have introduced the EasyFill link into their premium ‘Platinum’ range, this component makes it easy for a boiler owner to top up the central heating system pressure without the need to call for an engineer.

Benefits Of Combi Boilers

Unlike conventional boilers, combi (combination) boilers link a home’s central heating system and water heating; no separate hot water tank is needed which is cleaner as it avoids potential rust or debris build up while providing instant hot water. 

This allows a compact boiler which could fit into a larger kitchen cupboard or be wall mounted, to thoroughly heat a home without stealing lots of space. Combi systems are also easier to service or for boiler replacement due to their popularity, meaning greater availability. 

Baxi Platinum Combi Price

The Platinum combi is one of Baxi’s elite home heaters, and without installation, and output dependant can cost from between £883-£1147, a fair price for an excellent combi boiler.
