Founded in 1874, Vaillant has been producing quality, reliable and affordable heating solutions for over 140 years. One of the most popular boiler brands on the market, Vaillant’s boiler models regularly feature at the top of the ‘best buy’ lists.
As well as constantly refining and improving the energy efficiency of their boilers, Vaillant is also committed to green initiatives. Many of their models are compatible to use with solar panels and the ecoTEC exclusive Green iQ range of boilers are made with 85% recyclable materials.
All of the boilers that Vaillant design and manufacture are also Quiet Mark approved, which means you’ll hardly notice it - even when it is running at full capacity.
Vaillant combi boilers
There are 5 models in the Vaillant combi boiler range, all of which have an ErP efficiency rating of ‘A’. They are also available in different heating outputs, depending on the size of your home and your heating and hot water demands.
Combi boilers are incredibly popular for small to medium homes due to the space you save in not having to install a hot water cylinder and/or cold water storage tank (like you would for a regular or system boiler).
All of Vaillant’s combi boilers are compact and light, meaning they can be hidden out of the way and installed inside a kitchen cabinet or bedroom cupboard.

Vaillant regular boilers
Vaillant has two models in their regular boiler range: the ecoTEC plus and ecoFIT pure. Both are available in multiple outputs and are compact and light enough to be wall-mounted and installed inside a cabinet.
If you already have a regular boiler fitted in your home, then it’s an easy choice to replace it with a new regular boiler. This is because the existing pipework and cold water storage tank will already be installed.
Regular boilers are also ideal for homes that have more than one bathroom and a large demand for hot water from multiple outlets at the same time.

Vaillant system boilers
Vaillant offers three boilers in their system boiler range: the ecoTEC plus, the ecoFIT pure and the ecoTEC exclusive, which is made of 85% recyclable materials.
System boilers are similar to regular boilers in that they both need a hot water cylinder to store the domestic hot water, however system boilers don’t require a cold water storage tank as they connect directly to the mains water supply.
If you have a requirement for a constant supply of hot water but don’t want to install a tank in your loft, then a system boiler is an ideal choice.
