Vaillant Boiler Prices 2022
How much does a Vaillant boiler cost?
Looking for long term reliability in a boiler at a cost-effective price? If this is the first time you’ve looked at Vaillant boiler prices you may be pleasantly surprised, with prices starting at just £1995 including installation, or payments as low as £19.31 per month with OneHeat.
Despite Vaillant’s globally recongised reputation and international expertise, they’ve always tried to remain affordable, and through OneHeat we go further by keeping our Vaillant boiler prices as sharp as possible to help more people through the cost of living crisis.
Because Vaillant boilers are built with often superior designs to make them more robust, more energy efficient, and quieter.
This leaves you with a fantastic range of boilers that:
- Is reliable so you get the performance you want all year round without having to regularly pay a small fortune for repairs
- has a longer lifespan before you need to pay for a replacement
- saves you money on your gas bills by using the gas you pay for more efficiently
- runs more quietly so is less disruptive to the ambience in your home.
Vaillant achieve all this because they are simply one of the biggest names in the business, with a 141 year history and manufacturing sites in the UK, EU, Turkey and China.
With all that history and international expertise, its easy to understand how they’ve created such a famously strong reputation for quality.
At the smaller end of the Vaillant boiler range you can fit the EcoFit Pure 825 25kw, with prices starting at £1995 fitted.
The EcoFit Pure separates itself from many other Combi Boilers by being extremely small, designed to fit inside kitchen cupboards.
It is one of the view boilers in this category to be QuietMark approved, meaning that it makes little to no noise even in confined spaces in small flats and terrace kitchens.
While Vaillant provide a standard 2 year guarantee, with OneHeat this is extended to between 5 or 10 years, giving you up to a decade of peaceful mind.
Vaillant EcoTec Plus
Need something a little more powerful?
The EcoTec Plus is a mid-to-large range Combi boiler that promises hot water delivered in 5 seconds when paired into an appropriately sized property – much faster than many of the boilers on the market.
With a 5 year guarantee, extendable to up to 10 years with OneHeat, the EcoTec Plus 38Kw is often suitable for most multi-bathroom mid sized properties, handling hot water and heating easily for £2695 fitted.
Like much of the Vaillant range, the EcoTec Plus is also QuietMark rated, and due to the smart tech installed, it can drop to using 16% of its maximum power when it knows there is no big demand.

Larger detached homes with a substantial demand for hot water at peak times need to look towards the larger end of the Vaillaint combi boiler range for the high performance they need. Any bigger and it’s time to look at system boilers.
Like all modern combi boilers, your household can enjoy greater energy efficiency and control over your heating by install a smart thermostat and controls that can work together with your Vaillant boiler.
Vaillant have their own brand of smart controls called vSmart, SensoComfort and SensoHome, however most OneHeat customers prefer some of the large third party brands such as HIVE and NEST which we can have installed expertly and affordably for you, too.
We wouldn’t sell, fit and cover them if they weren’t. In fact, every time we fit a Vaillant boiler, our gas engineers allow themselves a little smile of satisfaction because they are certain that their customer will get satisfaction from the boiler itself.
But if you’re looking for more independent approval, Vaillant itself also has an “Excellent” rating on TrustPilot with over 17,000 reviews.
Vaillant boiler warranties and guarantees depend on the model, and range from 5 years to 10.
Some more compact models only come with a 2 year guarantee, but because OneHeat is Vaillant Advance, this gets bumped up to 5 years – another benefit of coming to OneHeat for your new boiler.
We LOVE both brands and believe this answer to this question is mostly subjective. In terms of performance, Worcester Bosch and Vaillant at their best to be firmly in the same league.
Our customers often comment that perhaps sometimes Worcester Bosch edges Vaillant when it comes to aesthetics, but we have as many happy Vaillant customers as we do Worcester Bosch customers.
The best Vaillant boiler is the one that best suits your home, the demands of your household, and that fits your budget.
That being said, the EcoTec Plus is a fantastic allrounder with reliable performance and is available in several different sizes and flow rates to suit a range of homes.
We’ll fit a Glow Worm magnetic filter on your new Glow Worm boiler unless a rare sitation means we can’t, or you tell us not to.
A correctly matched and fitted filter can add years to the boiler’s operational lifespan, and Glow Worm insist on one of their own filters for the sake of the warranty.
We’ll also fit a free limescale reducer and carbon monoxide detector too.
With OneHeat, your Vaillant boiler comes with:
- Your warranty/guarantee as discussed in your quote
- a FREE magnetic filter fitted (Vaillant)
- a FREE limescale reducer fitted
- a FREE wireless thermostat (Unless Nest or Hive as discussed during quotation).
Yes, we have 3x boiler care plan packages available to OneHeat customers.
All three of them come with annual servicing as standard, with prices starting at just £6.50 per month.
