Combi boilers (short for combination boilers) are so-called because they are capable of providing hot water as well as heat for your home. You don’t need a water tank if you have this type of boiler either, which is good news if space is an issue.
Choosing a combi boiler can be a time-consuming task. You need to make sure you choose one that is ideal for the size of your home, not to mention the number of people living there.
We’ve provided ten of the best below – any one of which could be just the thing you’re looking for.
Potterton Titanium 28HE
This is a great boiler from a well-known manufacturer. This model has a 24-hour timer and you also get the peace of mind of enjoying a five-year warranty on parts and labour. That’s one of the best deals on the market. This alone will make it the best combi boiler for many people. When you add in the power it has to deliver heating and hot water when you need it, you’ll see how practical it is.
Vaillant EcoTEC 937
This Vaillant boiler is a great choice if you have a larger home in need of a more powerful boiler. This gas boiler has an output of 28kW in terms of central heating and it can comfortably supply hot water to properties with more than one bathroom too. The Vaillant name is well-respected in the business so it might be just what you’re looking for.
Baxi EcoBlue Advance 33
This Baxi combi boiler has been designed with concealment in mind. If you want your boiler to be out of sight, this Baxi model will happily fit in a cupboard that is just 300mm in depth. It is one of the smallest on the market in this sense. However it is also powerful enough to be ideal for medium-sized properties with two bathrooms.
Worcester Greenstar 34CDI
The Worcester name is one that regularly comes up in positive combi boiler reviews. This model has the highest eco-rating possible so if energy efficiency is a big deal for you, this boiler will fit the bill. It also has a flue that can exit the boiler in a variety of directions, making it easier to work out the best position for the boiler in your home.
Glow-Worm Flexicom 30CX
Glow Worm boilers are well-known among many householders. If you’re looking for a boiler that is versatile yet can slot into a kitchen cabinet, this one might serve your needs rather well. It also comes with a rear flue option to completely hide its presence. Few people enjoy having a visible boiler on the wall in their kitchen. This one means you don’t have to go down that route.
Worcester Greenstar 42CDI
Another Worcester boiler worth looking at, offering a higher output of 30kW for a reasonable combi boiler cost. This gas boiler has one of the higher flow rates as well, which means it is able to deliver more hot water in the same period of time as some other boilers can manage. This is an important element to consider if you are looking for a boiler for a medium to large property.
Ideal Logic Plus 30
You may not be that familiar with the Ideal name but this combi boiler is easy to operate with the series of dials on the front that are easy to access. It is also more affordable than many other boilers on the market today. It still provides an impressive 24kW output which is ideal for smaller properties, and is powered by natural gas too. As such it would be a good choice if you have a smaller home, although it can still cope with medium-sized properties.
Heatline Capriz Plus 24kW
As you’ll notice this boiler has a slightly lower kW rating which means it is ideal for smaller properties such as flats. The price is very affordable indeed even with VAT included, and you can easily get to grips with operating the boiler thanks to the easy dials and the small panel on the front. While it is ideal for flats you could also install this in a small house that only has the one bathroom.
Baxi EcoBlue+ 24
This is an attractive-looking boiler that is designed to provide a good service for small properties such as flats. It has a smaller flow rate with 9.8 litres of hot water delivered per minute. It also provides a comfortable 20kW output which is perfectly fine if you live in a smaller property. The very low price also puts a tick in the right box if you are looking carefully at combi boiler prices yet you still want a good boiler for a smaller house.
Vaillant EcoTEC Exclusive 832
Another Vaillant entry on our list, this boiler manages to balance a reasonable price with a good performance. It is particularly good for properties requiring a higher kW output than might be possible with cheaper models. It provides up to 27kW for your convenience. In addition the flow rate is 12.9 litres per minute, which is fine for smaller properties with just one bathroom. And of course it is backed up by the quality of the Vaillant name.
There are of course many other boilers out there that offer a great service and are supported by a good brand name and manufacturer. As you can see though, it is important to consider the size of your property, the number of bathrooms and also how many people will be placing demands on it. This should help steer you towards the most appropriate combi boiler for your requirements. It is tempting to buy the cheapest one you can find but this can backfire on you if it isn’t powerful enough to meet your family’s demands.
So check out the list given above and consider your budget and needs before narrowing down the field to choose the best combi boiler for your property. We’ve also put together a guide on new boiler costs to help you budget.
