Why choose Vaillant?

Vaillant pride themselves in producing their boilers with values of high-quality, efficiency and innovation in mind. The brand strives to design each product with a capability of exceeding expectations and superseding its predecessors, Vaillant boilers are manufactured to cater to the ever-changing needs of the home environment. These boiler systems are manufactured with the aim of meeting the individual requirements of each household whilst also aiming to stay conscious of the environment.

Vaillant has received numerous accolades throughout the years, including being named one of the UK’s leading business brands, and being named an official “Superbrand.” These achievements are viewed by Vaillant as a testament to the high-quality products that they produce as well as a reflection of their company work ethic.

Vaillant boiler types

Within the Vaillant range, there are a number of boiler types, each with unique features and benefits. Here at HomeServe, we install a variety of Vaillant boilers and aim to help you select the ideal option for your home. Vaillant boiler types include:

Combi boilers

Vaillant combi boilers are designed to provide your home with on-demand hot water and effective heating. Combination boilers could be ideal for households looking for an efficient source of heat and tend to be best suited for smaller homes with a low to average demand for hot water.

Conventional boilers

The regular boilers manufactured by Vaillant provide central heating and hot water with the additional use of a hot water cylinder and cold-water tank. If you currently have a traditional style of central heating and aren’t looking to change this, a Vaillant regular boiler could be a suitable choice for your home. These boiler systems are generally ideal for households with multiple bathrooms and a higher than average demand for water.

System boilers

Vaillant system boilers are designed to heat your home effectively and require an additional sealed water cylinder to store hot water. With these boilers there is no need for cold-water tanks as the major heating and hot water system components are already built in. Vaillant system boilers are a great choice for most sized households with multiple bathrooms and a high demand for hot water.


Vaillant’s boiler range

HomeServe could provide you with a variety of choices from the Vaillant brand. Vaillant have manufactured a number of products throughout the years and we provide our customers with some of their most recent boiler ranges. These include:

EcoTec Pro

These boilers are designed to be energy-efficient solutions that provide both comfortable heating and instantaneous hot water. With innovative features such as a full range of thermostatic heating controls, these “super smart” boiler systems could allow you to access and control your home heating from your smartphone or tablet.

EcoTec Plus

The flexibility and variety of options provided by this range of Vaillant boilers are in our opinion, what makes them stand out from the rest. These boiler systems have a range of heating outputs and are therefore capable of meeting the demands of most households. Like the EcoTec pro range, EcoTec Plus boilers are intelligent and efficient, they have the ability to drop to using 16% of their maximum power if they detect that you don’t need as much heat, potentially saving you both fuel and money.

EcoTec Exclusive

These premium Vaillant boilers have superb capabilities in terms of performance, control and efficiency. Fully compatible with Vaillant’s vSmart smartphone app control, these boilers could be easily controlled whilst you’re on the go. These boilers have been bestowed with Vaillant’s Green iQ mark which is used to symbolise that these appliances could provide ultimate energy efficiency and the lowest fuel consumption and running costs.

Which Vaillant boiler do I need in my home?

With all the options available from the Vaillant brand, it can be difficult to decide which boiler would be suitable for your home. The HomeServe team is happy to be your first port of call when it comes to boiler conundrums, so don’t hesitate to contact us if you need help making your choice.

When making a decision about your new boiler, there are a number of factors that you should take into account. These include the Vaillant boiler prices, your hot water and heating usage and the space in your home. You should also consider the kW output that your home requires, which refers to a boiler’s ability to cope with your household’s hot water and heating demands and is reliant upon the number of bathrooms and radiators that are present in your property. Thus, if a boiler has a high kW output, it is more likely to be able to deal with a higher demand of hot water and heat.

Our team can provide you with a bespoke quote for your new Vaillant boiler installation, which includes a boiler model and kW output recommendation, as well as an estimate of how much the overall installation could cost. Once you’ve completed our online quote form, we can arrange for one of our trained surveyors to visit your home and help you choose the right boiler for you.

Here’s some extra information to help you with your decision. This estimated guide of kW outputs should give you some added insight into the type of Vaillant combi boiler you’d need for your home:

24-27kW 1-2 bedroom, 10 radiators, 1 bathroom
28-34kW 3-4 bedroom, 15 radiators, 1-2 bathroom
35-42kW 4+ bedroom, 20 radiators, 2+ bathroom

Visit our regular and system boiler pages to find out about the kW outputs that could be suitable should you choose to get a different boiler type installed.

Vaillant manufacturer-backed warranty

Manufacturer-backed warranties tend to provide most homeowners with an added sense of security and peace of mind in knowing that they are covered should they face issues with their boiler. An effective manufacturer-backed warranty could safeguard you against a number of boiler problems and could save you money in repair costs. Vaillant boilers usually come with manufacturer-backed warranties that range from 2-7 years.
