Vaillant boilers

If you're looking for a highly energy and cost-efficient A-rated (i.e. over 90% energy-efficient) boiler that guarantees quality, reliability and exceptional value, then a Vaillant boiler may be the answer. Founded in 1874, Vaillant has more than 140 years of experience in keeping families and homes nice and warm and is one of Europe’s leading heating technology manufacturers.

Why choose vaillant boilers?

Awarded German design & UK manufacturing expertise

If you choose a Vaillant boiler, you choose the pioneering excellence of German design and UK manufacturing expertise, crafted for modern homes and lifestyles. Thanks to their industry-leading technology, Vaillant have won the 2016 Which? Best Buy award for their entire range of ecoTEC domestic boilers.

Reliability & peace of mind

Vaillant are well known in the industry for the enviable quality of their manufacturing and the high reliability of their products. Vaillant boilers go through over 200 quality checks before they can leave the manufacturing plant for a reason – to guarantee that quality & reliability come as standard with every model. In fact, if you choose to have your Vaillant boiler installed by an accredited installer, you receive an extended warranty of up to 10 years.

Cost effective & energy efficient

The complete Vaillant boiler range is A-rated and operates at more than 90% efficiency, which means that more than 90p of every £1 you spend on fuel is effectively used to generate heat. In turn, G-rated boilers waste around 30p of every £1 you spend. What’s more, all Vaillant boilers are condensing boilers, which means that they recover heat from the exhaust gases that escape in the flue allowing you to cut down on carbon emissions and save money at the same time.

Vaillant combi boilers

Combi boilers are an all-in-one solution that serve as both a central heating boiler and hot water cylinder. Their space-saving quality and increased efficiency make them a popular choice among smaller and larger households alike. In fact, did you know that over 50% of all new domestic gas boilers installed in the UK are combi boilers?

Vaillant conventional boilers

Conventional boilers require both a hot water storage cylinder and a water tank (or cistern) and can provide large volumes of hot water to multiple bathrooms. They’re also known as heat only, traditional, open vent and regular boilers.

Vaillant system boilers

System boilers work on the principle of stored hot water – much like conventional boilers. However, system boilers differ from conventional boilers in that the individual components are built directly into a system boiler, which makes the installation a lot quicker and less expensivce. In addition, system boilers do not necessarily need a water storage tank, which makes them a great choice for homes where space comes at a premium.
