Vaillant ecoFIT Pure System Boiler

The Vaillant ecoFIT Pure System offers flexibility, low emissions and high energy efficiency for homes of all sizes.

This powerful boiler by Vaillant has been awarded Which? Best Buy status and the Quiet Mark accreditation. The boiler’s compact size allows for kitchen cupboard installation and its high-quality build hasn’t gone unnoticed by engineers and customers. If you’re looking for a reliable gas boiler that is smart compatible and has a high-efficiency rating, you should definitely take a closer look at the ecoFIT Pure System.

How Much Does this Boiler Cost?

The Vaillant ecoFIT Pure System series is made up of five models, including heat outputs of 12kW, 15kW, 18kW, 25kW and 30kW. Prices vary according to these outputs and typically range between £840 and £1,160 including VAT. Don’t forget, you’ll need to factor in the cost of installation, so it might be best to get quotes that include the price of the boiler and the fitting work. As prices also differ between suppliers and installers, we also suggest you shop around and compare quotes to increase your chances of finding some great deals.

How will I know if this Boiler is Suitable for My Home?

Vaillant’s ecoFIT Pure System is a system boiler and, like all boilers of this type, will need a separate cylinder for storing your hot water. Most people with a system boiler keep the cylinder hidden away in their airing cupboard. System boilers are often found in homes with multiple bathrooms because they can provide a constant supply of hot water to taps, even when they are all running at the same time. Another plus point is that they don’t require any tanks in the loft.

As this system boiler comes in a range of outputs, it’s best to ask a Gas Safe registered engineer to assess your heating and hot water demands to help you determine the right size. Whilst visiting for your property, an engineer will be able to confirm if a system boiler is the best type of boiler for your home and lifestyle.

Is it a High Efficiency Boiler?

It’s an incredibly efficient A-rated system boiler with an ErP rating of 94%. To be honest, they don’t come much better than this, which is why this boiler is Energy Saving Trust endorsed. The Vaillant ecoFIT Pure System is also rather smart because it can reduce its maximum output to as low as 20% whenever it detects that your home needs less heat. So, not only will this boiler use less energy but it should save you a heap of cash on your fuel bills.

Does this Boiler have a Good Range of Controls and Features?

Yep. One of the nice things about this boiler is the bright LED display that is clearly visible when installed in a dimly lit area of your home. User controls include the usual suspects, such as a reset button, pressure gauge and heating and hot water temperature switches. If you want to improve performance and efficiency, you can buy some excellent optional controls and accessories including uniSTOR hot water cylinders and the vSMART app-based control that lets you manage your heating when you’re at home or away. Other key features include top and rear flue options for flexible siting possibilities and an impressive aluminium heat exchanger.

How long is the Warranty on this Boiler?

The ecoFIT Pure System has a 2-year parts and labour warranty as standard, but you may be able to extend this when you hire a Vaillant Advance installer to fit the boiler.
