Written By:

Updated on



Are you looking for boiler prices for Baxi, one of the most popular brands on the market today?

Then you’re in the right place.

In this guide, you’ll discover everything you need to know about Baxi’s boiler prices, including the different models and where you can buy them.

What’s in this guide?

Baxi Overview

Baxi spans back to 1866 and boasts an extensive network of experienced engineers of over 200 skilled professionals. This brand helps heat millions of customers around the UK, with many businesses in their portfolio, including Potterton, Heatrae Sadia, MegaFlo, and Main Heating.

Their products are energy-efficient, with a wide range of heating systems, including combination, system, and heat only boilers. Baxi puts social and economic sustainability at the forefront of their business, which you can see reflected with their affordable heating systems.

Baxi Combination Boiler Prices

Combination boilers are one of the most popular types of boilers on the market today. They are a perfect space-saving solution because you won’t need a cold water tank or a hot water cylinder.

Combination boilers take their water from your main supply, then deliver it to your taps or shower directly. You can often find these boilers in a wide range of power outputs and prices, and they are known to be very energy-efficient and low-cost to run.

Sometimes, you could find a Baxi combination boiler for as low as £624, making them one of the most affordable on the market.

Baxi offers a wide range of models, from lower outputs suitable for one- or two-bedroom homes to those that can heat 5-bedroom homes with 2 or more bathrooms.

Baxi System Boiler Prices

System boilers utilise the water from your main supply like combination boilers. However, they do require a hot water cylinder.

One of the benefits of this system is that you can use hot water in several locations at the same time. However, once you have used up all the hot water, you’ll need to wait for more to be heated again.

System boilers tend to be slightly more expensive than combination boilers, and you need to consider the price of your cylinder as well. Still, they might be more economically friendly to run than other alternatives.

Baxi Heat Only Boiler Prices

Heat only or ‘regular’ boilers require both a cold water tank and a hot water cylinder to store the water for your taps and central heating system. This makes this boiler type increasingly less popular, because they require a lot of space and are best suited for larger homes. A smaller home would likely benefit more from a combination boiler that can fit into a kitchen cupboard.

However, heat only boilers tend to be less expensive than system boilers. They can also have the same price as combination boilers, but you need to consider the price of a hot water cylinder and cold water tank.
