Thanks to a long history in boiler manufacturing, Vaillant has made continual adjustments to its product range throughout the years. This means that buying a boiler from this highly experienced company comes with some key benefits.
All of Vaillant’s products are handmade. This allows for finer inspection and greater quality control to ensure your new boiler is up to spec.
Almost all of Vaillant’s boilers are A-rated. Not only does this save money, but it helps reduce the environmental impact of a huge number of boiler replacement upgrades each year.
Excellent Customer Service
Besides the customer feedback shared on its website, Vaillant boasts around 14,000 excellent customer reviews on Trustpilot – one of the most trusted review platforms all around the world.
With an average score of four stars out of five, this amazing popularity among customers testifies that the brand is headed in the right direction.
High Which? Scores
Awarded with the Which? ‘Best Buy’ tag, Vaillant boilers score top marks in almost every category, such as build quality, engineer recommendations, ease of servicing, customer scores, ease of fixing a common fault, and availability of parts and spares.
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.
Here are some key aspects of Vaillant’s service plans:
Diverse Heating Controls
Vaillant allows customers to choose from an extensive range of thermostats and controls that help in reducing fuel costs.
Compatible with both modern and traditional thermostats, Vaillant’s vSMART technology can even allow homeowners to control their new boiler from a smartphone.
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.
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, small combi boiler, or new installation.
We hope that our Vaillant price guide has helped you determine if this manufacturer is the right one for you.
