#1 best boiler brand – Viessmann

Viessmann Boiler

Viessmann is the largest European boiler manufacturer. This brand can be a great addition to your home if you want to bring German engineering inside.

Viessmann boilers are renowned for their energy efficiency and longevity. They have been awarded a Which Best Buy Boiler award for being able provide hot water and heating when you need them.

The company’s best boilers include the Viessmann Vitodens 050-w, an excellent choice for top quality value natural gas boilers, as well as the Viessmann Vitodens 100-W which is one of the most efficient combi boilers.

Viessmann boilers excel in technical detail, which is an advantage over other brands. They use stainless steel heat exchanging units instead of the aluminium used in most boiler brands.

The heat exchanger is crucial and produces hot water. This component is often overlooked by boiler manufacturers, who choose to build them with less durable materials in order to increase their longevity. A faulty heat exchanger will mean a new boiler. So even in you need an exceptional boiler for a 3 bedroom house, we strongly recommend the Vitodens 050-w 30kw combi

2nd Best Brand – Worcester Bosch

Worcester’s boiler guarantee is unlike traditional warranties. It means that the manufacturer will repair any malfunctioning device. Worcester Bosch is a well-known leader in aftercare.

The exact guarantee period will depend on which boiler you choose, and what Worcester-branded products that you use. The Worcester Bosch system filter can be added to extend the guarantee by one year.

Worcester Bosch is an all-rounder that offers high-quality, award-winning boilers at affordable prices. Even the Powerful Worcester 8000 40kw combi is within reach with boilers on finance.

This is combined with their outstanding guarantee, customer service, and easy-to-source parts, and you have one of the most trusted boiler brands in the UK.

Ideal boilers has a wide range of boilers, from affordable models to more expensive options with all the bells & whistles you need.

Ideal Logic combi and system boilers from the company are a great choice for small homes. They’re extremely compact and efficient, which will help you save money on your energy bills.

Combi boilers work well if there are less bathrooms or showers in your house, while system peers will be more suitable if there are high-demand hot water requirements. You can also run them on a 20% hydrogen mix off the shelf.

Ideal’s system and combi boilers have warranties that range from 7 to 12 years. This is the longest Ideal boiler warranty on the market. However, you will need a Max-certified installer in order to get the 12 year warranty. Without one, it’s still quite long at 10. However, regular boilers come with shorter warranties — between 2 and 7 years depending on the model.
