What Is a Vaillant Combi Boiler?
A combi boiler, short for combination boiler, provides both heating and hot water from a single unit. It heats water directly from the mains when needed, so there is no requirement for a separate hot water cylinder or cold water storage tank.
Vaillant combi boilers are often a good choice for homes with one or two bathrooms where space is limited. If you’re unsure whether a combi, system or regular boiler is best for your property, our engineers can advise on the most suitable option.
The Vaillant Combi Boiler Range
Vaillant is one of the UK’s most recognised boiler manufacturers and has consistently been regarded as a leading name in gas heating. Their combi boiler range covers three models, each designed for different property sizes and requirements. All are A rated for efficiency.

The ecoTEC plus is Vaillant’s flagship combi boiler and one of the most widely installed in the UK. Remastered with a modern design and improved efficiency, it suits medium to larger homes with one or two bathrooms.

Is a Vaillant Combi Boiler Right for Your Home?
A combi boiler works well in many homes, but it is not the right choice for every property. Here is a straightforward guide.
A Vaillant combi boiler is likely to be a good fit if:
- Your home has one or two bathrooms
- You don’t have high simultaneous hot water demand
- Want to free up space by removing a cylinder or loft tanks
- Are replacing an existing combi boiler on a like for like basis
A system or regular boiler may be a better option if:
- Your home has three or more bathrooms
- Multiple people regularly use hot water at the same time
- You have an existing cylinder setup that works well for your household
If you are unsure which type suits your home, our engineers will assess the property and give you honest advice. We never recommend a combi boiler where a system or regular boiler would serve a household better. Visit our main Vaillant boilers page for an overview of all three types, or read our boiler installation guide for more detail.
Vaillant Combi Boiler Guarantees
The ecoTEC plus range comes with a standard 5 year guarantee. The ecoTEC pro and ecoFIT pure both come with a standard 2 year guarantee. All three models can be extended to up to 10 years when installed by an accredited myREWARDS installer and registered with the correct Vaillant boiler protection kit or filter.
As accredited Vaillant installers, we register your boiler and guarantee directly with Vaillant as part of the installation process.
