Product Description

The 625 is a condensing regular gas boiler by Baxi that has been designed for internal wall-mounted installation.

How efficient is the Baxi 625?

An efficiency rating of 93% gives the Baxi 625 an ErP A-rating and makes this a highly efficient unit.

Is the output rating suitable for my home?

An output rating of 25 kW means that the Baxi 625 is best suited to medium-sized homes with around 15 radiators.

Are any other options available in the Baxi 600 Heat range?

To help you find the most suitable regular gas boiler for your home, Baxi offer a number of output ratings in this range. On top of the 25 kW model, there are also 13 kW, 16 kW, 19 kW and 30 kW models too.

Is a regular boiler suitable for my home?

Regular boilers, also known as heat only boilers, need to be installed as part of a heating system alongside a hot water storage cylinder, cold water storage tank and a feed and expansion tank. This means that a regular boiler isn’t really suitable for properties where space is limited.

How long is the warranty period?

Featuring a 7 year warranty as standard, the Baxi 625 is well covered in the unlikely event of a fault.

What are the key features of the Baxi 625?

Baxi 625 boilers have no pump overrun and no permanent live switch is required. The units are suitable for fully-pumped, open-vent or sealed systems and feature an easy fit wall-mounting bracket, front and side access, a central top flue, as well as a rear flue option for complete flexibility when it comes to installation.

How big is the Baxi 625 Heat?

Baxi 600 Heat boilers have compact dimensions of 625x370x270mm (HxWxD) which allow for installation within a standard kitchen cupboard.
