Whether you’re a landlord trying to maximise profit or a homeowner looking for value for money, the cost of replacing your boiler can be significant. Replacing your boiler isn’t a DIY job and requires the help of an approved and registered tradesman. A survey was done very recently to find the best boiler, so here we look at which models make up the top 3 boilers.

What is a combi boiler?

Before we look at which combi boilers are best, we need to look at what a combi boiler is, what it does and what the advantages of having one are. The combi boiler is the UK’s most popular type of boiler. It supplies both the hot water and heating in a home and doesn’t rely on any hot water storage tanks or cylinders. A combi boiler can be gas, electric or oil-fired.

Advantages of having a combi boiler

The combi boiler is very efficient as it provides both central heating and hot water for the home from one compact unit. Mains cold water is connected directly to the boiler and this is heated once a call for hot water is made by opening a tap. This eliminates the requirement for a water tank, saving space in your home.
The main benefits of a combi boiler include:
  • hot water on demand, instantaneous and unlimited
  • no requirement for a hot water tank in the loft or cupboard
  • no water pump required as water is delivered at mains pressure
  • saves installation space and frees up living space

The best combi boiler brands and guide to installation costs

All boiler manufacturers – and there are lots of them – have their own considerable range of boilers to cater to the needs of different sized households. For example, Worcester Bosch has a range of 13 different combi boilers. Vaillant also has a range of 13 different combi boilers.
So, for this guide, we will only concentrate on the most popular sized home which is a 3-bedroom home. The following combi boilers are rated the best in terms of value for money, warranty and reliability:

Choosing which boiler is suitable for your property can be both stressful and challenging but hopefully, this article helps you narrow down your choice of boilers. Every boiler manufacturer has a boiler sizing calculator which can help you find the right sized boiler for the number of radiators you have. More importantly, your gas safe registered engineer will be able to correctly size your boiler for your hot water needs – which differ from household to household.
All the boilers listed above are below £1,000 and priced within £100 of each other. The boiler installation prices in this article will help you budget for your boiler replacement and help you decide when a ‘deal’ either seems too good to be true or just expensive.
Baxi, one of our personal recommendations, offer the longest standard warranty of 7 years which can be extended - if you pay extra - to 10 years. Choosing either the Baxi or one of the other two will mean you have reliable hot water and heating for many years to come.
