What Boilers Do Vaillant Manufacture?

Vaillant produces boilers to suit every usage scenario. Whether it be economical combi boilers, highly powerful system boilers, or versatile regular boilers, read our full guide on the best boiler brands for more information on which is the best manufacturer.

Vaillant ecoTEC

Most of Vaillant’s boilers are produced under its ecoTEC branding, which contains several options:

Vaillant ecoTEC Exclusive

The ecoTEC Exclusive range is the brand’s flagship model; this winner of the 2018 Housebuilder Products Awards brings with it impeccable efficiency and controls, allowing homeowners to finetune their central heating with ease. This is one of the most energy-efficient combi boilers right now. Look out for the ecoTEC Exclusive with Green IQ range.

Vaillant ecoTEC Plus

The second option in the ecoTEC lineup is the ecoTEC Plus model. Available in combi and system formats, the ecoTEC Plus model is pitched as being a competent all-rounder, capable of powering homes of various sizes.

Vaillant ecoFIT Pure

The ecoFIT Pure range packs all of the same features as other ecoTEC boilers, albeit within a reduced physical footprint. This ecoFIT pure is as you can probably guess from the name, perfect for kitchen cupboards.

Vaillant ecoTEC Pro

Finally, the ecoTEC Pro range of combi boilers offers a no-nonsense approach to central heating. With easily adjustable controls and formidable performance, an ecoTEC pro is a great option for homeowners looking for a simplistic boiler to complement their home’s heating system.

What Factors Influence the Price of a Vaillant Boiler?

The Boiler’s Size

Different power suppliers might affect the cost of your boiler’s supply. A condensing combi boiler at the highest end of the power supply range of 43 kW may cost £1,800, whilst something smaller, such as the 25 kW, can cost as little as £850.

It is critical to understand what size boiler you require and to avoid purchasing a boiler that is too powerful for your home size since this will essentially be a waste of money.

The Kind of Boiler

Combi, conventional, and system boilers are the three types of boilers. Each of these boilers has a distinct price tag.

When You Want to Move Your Boiler

You may decide to relocate your boiler from its original location, which may result in greater labour rates. This can take several days to accomplish, therefore your labour expenses are likely to be greater than those of homeowners who just replace

Where you live

Your labour fees may be greater or cheaper depending on where you live. The cost of living in capital cities will be higher than in more rural towns and villages, costing closer to £1,500 for labour against £500 in smaller areas.

For example, a London Boiler Installation may be different to a Manchester Boiler Installation.

Vaillant Combi Boiler Prices UK

New Vaillant combi boiler prices start at around £850 for its ecoFIT Pure 25kW, up to its powerful ecoTEC Plus 38kW at around £1,500. You can compare all the latest Vaillant combi boiler models in our table below but remember that all these do not include installation by a Gas Safe registered heating engineer.

High Which? Scores

Compelling Service Plans

Vaillant’s boiler servicing plans are some of the most feature-rich available. They keep newer boilers running for longer and can sometimes work out cheaper than occasional engineer call-outs.

  • Repairs are made using genuine Vaillant spare parts

Diverse Heating Controls

Compatible with both modern and traditional thermostats, Vaillant’s vSMART technology can even allow homeowners to control their new boiler from a smartphone.

Warranty Options

Many of Vaillant’s products come with a standard warranty of between 2 and 5 years. However, this warranty can be extended up to 10 years if the boiler is installed by a Vaillant advance installer.

You can get 12 years warranty with some manufacturers so if you compare boiler quotes you can ensure you get the best deal.

Vaillant Boiler Cost – Our verdict

If you’re looking for a well-built boiler that can handle almost anything, a Vaillant boiler could be your best choice.

Due to its handmade nature, a Vaillant boiler may cost slightly higher than the competition. However, reliability is paramount and the handmade manufacturing process helps ensure each and every model is built with precision.

Do they offer the best combi boiler, system or regular boilers? We’re not convinced.

One aspect in which Vaillant, unfortunately, falls short is through its warranty periods. Vaillant’s standard warranties are by far some of the shortest we’ve seen, with many other manufacturers offering a 10-year warranty without any additional cost.

Despite this, all in all, we have no trouble recommending a Vaillant boiler to anyone looking for a heating upgrade, a small combi boiler, or a new installation.

How much is a new Vaillant boiler fitted?

If you are considering a new Vaillant boiler cost, unless you are a fully trained Gas Safe heating engineer or have similar qualifications, you will have to pay for the installation. The cost of a Vaillant boiler with fitting will be around £2,400 for the base ecoTEC model, including all parts and labour required.

Are Vaillant boilers expensive?

It is well known that the prices of Vaillant boilers can be quite expensive due to the way that they are manufactured. Vaillant state that their models are handmade, therefore, increasing labour costs, which in turn makes the price of a Vaillant boiler higher than most.

Which is the best Vaillant ecoTEC combi boiler?

The main range of boilers from Vaillant is the ecoTEC range, of which there are also different models of, starting with their entry level ecoTEC Pro, right up to the ecoTEC Exclusive with Green IQ. Vaillant says that the ecoTEC Exclusive with Green IQ is their best and most economical gas boiler.

Recently had solar panels fitted by Green Central and I can’t speak highly enough of the team. The whole experience has been trouble free and I would recommend them to anyone thinking about having solar panels installed – 10/10!

Rob Schofield


Our installation is now complete! 8 solar panels fitted and the journey from initial consultation through to the end product has been seamless.
Hats off Green central, Credit where it’s due.

Recently had six solar panels fitted on my house by Green Central and I couldn’t have asked for a better service. In particular, I have to highlight the exceptional communications through out, the over all smooth running process and completely stress free experience, all down to Green Central. I now have grid independence which is valuable beyond estimation.
