Vaillant is the second-largest boiler manufacturer on the continent and a European titan in the heating industry, renowned for their German engineering and excellent reputation among both customers and gas engineers.
If you can’t get German engineering in your garage, Vaillant at least gives you another way to profit from great mechanics.
One of their most popular range of gas boilers in the UK is the Vaillant ecoTEC, which has built a reputation among installers as one of the easiest boilers to repair.
That’s not just good for engineers, but also for people who pay the engineers by the hour.
Aside from gas boilers, the brand also offers a comprehensive range of heating and cooling products, including combi, system and regular boilers, as well as heat pumps.
By securing a new gas boiler from the Vaillant brand, you can be secure knowing that your boiler has been designed and manufactured by esteemed German engineers - not to be confused with German steam engineers.
All modern Vaillant boilers also use condensing technology and are A-rated, this means that they are at least 90% efficient, helping you to save even more on your heating bills.

History of Vaillant Boilers
Vaillant was founded in 1874 by Johann Vaillant in Remscheid, Germany and still remains a family business. Please note that Johann himself is no longer active in the business.
The business was birthed when Johann patented the first gas-fired bathroom boiler and began manufacturing them for the mass market.
Since then, the company has gone from strength to strength and in 1961, they launched the Circo Geyser, which was the world's first wall-hung circulation heater.
Today the company concentrates heavily on innovating in the green space and in 1995 was the first boiler manufacturer to release the first boiler to use condensing technology, a huge feat that revolutionised the efficiency of modern gas boilers.
In 2008, Vaillant demonstrated their commitment to the green heating revolution by launching its very first heat pump range.
Although your Vaillant product is green by nature, it usually comes in white, so you don’t have to adjust your house’s colour scheme.
Vaillant Gas Boilers
Vaillant gas combi boilers are one of the most efficient and convenient types of boilers you can use.
Combination (or combi boilers) are by far the most common type of boiler in the UK, installed and used in as many as 70% of homes.
Modern A-rated combi boilers offer over 90% efficiency and provide both on-demand hot water, and heating in one compact unit. We reckon that version from 1874 was a lot less compact.
This means that, unlike other types of boilers e.g. system and regular, you do not need to use or have a separate hot water storage tank installed, helping to save space and make installation easier. Like an attractive grocery store promotion, this gets you a two-for-one deal.
It also means you don’t have to worry about the hot water running out within the storage tank, which is of course a limited amount of water and not provided on-demand, like a modern combi boiler.
Check out our comprehensive guide of the best combi boilers on the market for a more thorough comparison.

Some of the most popular Vaillant combi boilers include the following:
Vaillant ecoFIT Pure Combi
Vaillant ecoTEC Pro Combi
Vaillant ecoFIT Plus Combi
Vaillant ecoTEC Exclusive with Green iQ Combi
Vaillant Gas Regular Boilers: Price Range
Just like a combi boiler and building an open fire in your kitchen a heat-only or regular boiler can provide both heating and hot water. The three boiler types are the only safe option.
However, unlike a combi boiler, it requires a separate hot water storage tank, since it doesn’t take the hot water from the mains or heat it up on on-demand.
Essentially, a combi boiler is the water-heating version of streaming your video instead of buying a VHS.
Regular boilers are typically more suitable for larger properties with multiple water outlets e.g. multiple bathrooms since they can keep up with the high hot water demand. Rumour has it Buckingham Palace has multiple bathrooms and therefore a regular boiler.
The cost of a new regular boiler can range from £800 to around £2500.
As mentioned above, this is the price for the boiler only and does not include the Gas Safe installation. To get a fixed price on a brand-new regular boiler which includes installation and everything you need, click here.

Some of the most popular regular boilers include the following:
Vaillant ecoFIT Pure Regular
Vaillant ecoTEC Plus Regular
Vaillant Gas System Boilers: Price Range
System boilers are a modern advancement on regular boilers and are also more appropriate for large homes/and those with a high demand for hot water, like families with twelve children in dire need of a bath. For example, homes with multiple bathrooms and water outlets may be in use simultaneously.
They are distinct from regular boilers since having more internal components e.g. their own water pump, meaning no water tank is required to be stored in the loft or an even more inconvenient spot in the house.
Similar to combi boilers, they heat water from the mains water supply but instead of diverting it directly to water outlets e.g. taps, baths or showers, it is stored in a hot water tank (the water being hot, the tank is usually a normal temperature).
The cost of a standalone Vaillant system boiler ranges from £700 to £2,000 and they are available in a range of different sizes. However, remember that he is for the boiler alone. Not the flue, controls, installation or anything else that’s essential or you may like to have.

Here are the main boilers offered by Vaillant in their system boiler range:
Vaillant ecoTEC Plus System

Vaillant ecoTEC Exclusive with Green iQ System
Vaillant Boiler Warranty
A boiler warranty is a crucial consideration when shopping for any new boiler, as you want to be confident that in the event the boiler breaks down, it will be repaired and up and running as soon as possible, or at least as soon as you’d like your showers to be warm again.
So what type of warranty does Vaillant offer?
Unlike brands such as Worcester Bosch, the warranty length with Vaillant depends on the boiler model you choose, but it ranges from 5 years to 10 years - something you could only wish for with most of your fancier gadgets.
For example, the Vaillant EcoTEC Pro comes with a standard 2-year warranty, while the Vaillant EcoTEC Plus comes with a 5-year warranty.
This isn’t the best, especially when you start to compare it to other boiler manufacturers' warranty offerings. For example, a boiler guarantee offered with Worcester Bosch boilers is 10 years (when purchased via Heatable).
