The best boiler for your home will depend on the size of your property and typical heating and hot water usage
In an ideal world, there would be a one-size-fits-all boiler solution but, sadly, this isn’t the case. As each household is unique, boilers must come in various types and lot of different sizes to suit the needs of each home and its inhabitants. When it comes to finding your perfect boiler, many important things need to be taken into account, such as your budget and the size of your property, as well as your heating and hot water requirements.
To help you determine which boiler is best for you and your home, we’ve put together a guide on the main boiler types and some of the leading boiler brands.
The Best Type of Boiler for Your Home
There are three main boiler types including combi boilers, system boilers and regular boilers, all of which have their own set of advantages. We’re now going to look at each boiler type in more detail so that you can find out which is best for your property. Please be aware that the prices listed in the tables below are for the boilers only and do not include the cost of installation.
Combi Boilers
Combi boilers (or combination boilers) provide heating and hot water from one compact unit, meaning they don’t require a separate hot water cylinder or any tanks. They are the most popular type of boilers in the UK because combi units are easier to install and usually cheaper than system and regular models. Available in a wide range of sizes (kW outputs), combi boilers are generally best for smaller homes. As combi boilers tend to struggle to cope with two showers or baths running at the same time, they are not really suitable for properties with multiple bathrooms.
The advantages of combi boilers include:
- Instant and unlimited heat and hot water
- Heat water on demand
- Extremely energy efficient
- Great for homes with limited space as no cylinder or tanks required
- Easier to install (saves you money)
Let’s take a look at some of the best combi boiler models on the market today.

Viessmann | Vitodens 200-W 26 Combi | 26kW | 14.0 l/min | ![]() | £1,516.24 |
System Boilers
System boilers need a separate water cylinder for storing hot water, which is usually found in the airing cupboard. They don’t require any additional tanks in the loft though, making them ideal for homes with minimal loft space. Like combi boilers, system boilers are easy to install, energy efficient and economical to run. The major difference is that these boilers are a great choice for properties with high demands and more than one bathroom because they can provide a constant supply of hot water to all of your taps at once.
The advantages of system boilers include:
- Can provide hot water to multiple taps at the same time
- Built-in components make installation quick and easy
- Ideal for larger homes with two or more bathrooms
- No need for separate tanks in the loft
- Compatible with solar thermal solutions
Here are just some of the best system boilers that may be suitable for your home.

---|---|---|---|---|---|

Vaillant | ecoTEC Plus 630 System | 30kW | N/A | ![]() | £1,228.03 |
Regular Boilers
Also known as conventional, traditional or heat only boilers, regular boilers are generally recommended for homes with multiple bathrooms and properties in areas where water pressure is low. As regular boilers require a hot water cylinder and a feed and expansion tank, they are best for homes with a sufficient amount of airing cupboard and loft space. What’s more, these boilers can provide a consistent supply of hot water, regardless of how many taps you are using simultaneously.
The advantages of regular boilers include:
- Cope well with any number of taps running at the same time
- Perfect for larger properties with two or more bathrooms
- Best for homes with a traditional central heating system
- Can be installed alongside an immersion heater (in case the boiler breaks down)
- Compatible with solar thermal solutions
If it turns out that a regular boiler is the best option for your home, you may want to consider some of these top-rated models.
BRAND | MODEL | OUTPUT | MAX FLOW RATE | EFFICIENCY | TYPICAL PRICE |
---|---|---|---|---|---|
Ideal | Logic+ 30kW Heat | 30kW | N/A | ![]() | £995.99 |
