Boilers

Shop high-quality boilers from trusted brands like Ideal Boilers, Vokera, Vaillant and Baxi. At Toolstation, you’ll find gas combi boilers and system boilers compatible with most central heating systems.

What Are the Different Types of Boilers?



Combi boilers are a popular choice for many homes, heating water as you need it. They are smaller and more compact than system boilers, making them easier to install in any property.

System boilers store hot water in a cylinder after heating it, producing higher volumes on demand. They can be helpful for homes with two or more bathrooms. However, once the hot water supply has been used up, you’ll have to wait for the boiler to heat more.

Browse our full range of boilers and related accessories here, or check out our Boiler Buying Guide for more tips and advice on finding the right one for you.
