Vaillant Combi Boiler Prices Range Between £858.00 and £1,916.88 and are Flexible and Efficient
Great for properties with limited space, combi boilers heat water directly from the mains so you won’t need a separate cold water tank or hot water cylinder with Vaillant’s combi models that range from 24kW to 40kW. They do, however, tend to struggle to cope with more than one tap running at the same time.
The brand’s combi boiler line includes the ecoFIT Pure Combi with high-spec heat exchanger, as well as the ecoTEC Exclusive Green iQ Combi with an impressive 1:10 modulation range and special Green iQ mode to reduce gas consumption. Other options include the ecoTEC Pro Combi and ecoTEC Plus Combi which, like all Vaillant combi models, are Quiet Mark approved for being extremely quiet in operation.
Prices range from around £858.00 to £1,916.88, and the amount you will need to spend will depend on your chosen model and size. The ecoTEC Pro and ecoFIT Pure come with a standard 2-year warranty, whereas the ecoTEC Plus and ecoTEC Exclusive Green iQ are covered for 5 years.

Since they can supply a lot of hot water at once, regular boilers are practical solutions for homes with multiple bathrooms and households with large requirements.
Two models make up the Vaillant regular boiler range – the ecoFIT Pure Regular and the ecoTEC Plus Regular both available in outputs from 12kW to 35kW. Each model is user-friendly, has built-in frost protection and is compact enough to fit in a standard-sized kitchen cupboard. Furthermore, these boilers can be used with a wide range of optional energy-saving controls.
When it comes to price tags, you can expect to pay anything between £715.22 and £1,522.42. The ecoFIT Pure is backed by a 2-year parts and labour warranty, and the ecoTEC Plus has a more desirable 5-year warranty.
