Frequently Asked Questions


How large is the Baxi 428?

The 428 is crafted to be one of the most compact boilers that Baxi produce. Boilers are often cited as an obstruction in homes, especially bathrooms, but the Baxi 428 doesn't compromise anything when it comes to its dimensions. That’s why, at only 700x395x297mm, it is one of the smallest combi boilers on the market. It installs within a standard kitchen cupboard without sacrificing any convenient features.

Will it provide enough heat for your home?

The Baxi 428 is a household combi boiler which has an output rating of 21.8 kW for central heating and 28 kW for domestic hot water (DHW) and therefore could potentially be used in properties with up to 10 radiators and a single bathroom.

What is the warranty period of this boiler?

The Baxi 428 has a 5 year parts and labour warranty included with the purchase of this boiler. This is one of the longest cover times that we've seen from a company for a combi boiler, so it's great to see that you'll have peace of mind when using this product.

What are the most important features of the Baxi 428?

The 428 boiler is ideal for installation in smaller properties, as well as in larger ones. The slim design of the boiler means that it can fit into spaces where many other boilers simply would not go. The Baxi 428 boiler also offers you a huge range of optional extras which can be installed to help make your life a lot easier when using your boiler on a daily basis.

This boiler has a smartphone control system and a rigid filling loop as well as optional stand off frame to make installation of this boiler much easier.

Should you buy a combi boiler?

A combi boiler is best suited to smaller households with just 1 bathroom (potentially 2). They connect directly to the mains and heat water as and when it’s needed, which cuts out the need for a bulky tank. If you use lots of hot water, a combi boiler could be best for you.

What about efficiency?

The Baxi 428 boiler has been awarded an ErP A-rating, meaning that it will only use a minimum amount of energy while still heating the house and providing hot water. The boiler is also meant to save you money as it has an efficiency rating of 93%.
