Vaillant ecoFIT Pure Regular

The Vaillant ecoFIT Pure Regular features the latest boiler technology and is compatible with the vSMART app-based heating control.

Vaillant is a leading brand that is popular with engineers and homeowners because it never fails to develop impressive boilers, such as the ecoFit Pure Regular. This conventional boiler offers superior performance, excellent energy efficiency and is compact enough to be sited in a kitchen cupboard. Suitable for small, medium and large homes, the boiler can be used with a range of heating controls including the vSMART app-based controller.

How Much Does this Boiler Cost?

Prices range from £730 to £1,440 including VAT, depending on which heat output you need. The Vaillant ecoFIT Pure Regular can be supplied with an output of 12kW, 15kW, 18kW, 25kW, 30kW or 35kW, and the higher option is usually the most expensive. You must select the right output for your home to ensure the boiler can meet your heating and hot water demands, so we recommend you seek advice from a Gas Safe engineer. If you shop around and compare prices from different suppliers and installers, you may be able to save some cash on the boiler.

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

This boiler is called a regular boiler (also known as a conventional or heat only boiler) and is ideal for households that tend to use a lot of hot water or need to run multiple taps or showers at the same time. All regular boilers require a cold water feed tank in the loft, along with a hot water storage cylinder (usually kept in an airing cupboard). Seeing as this boiler must be installed with separate components, it is best suited to properties looking to replace an inefficient regular type boiler.

We must stress the importance of selecting the correct boiler type and heat output for your home. If you pick a boiler that is too big, you’ll notice an increase in your fuel bills because it will use more energy than is necessary. Choose a boiler that is too small and it won’t be able to keep up with your demands. To know the right boiler type and output for sure, you should consult a Gas Safe registered engineer prior to buying a replacement.

Is it a High Efficiency Boiler?

Yes, it is. Vaillant is known for manufacturing energy efficient boilers that help to reduce your bills and carbon footprint. If you purchase the ecoFIT Pure Regular, you can rest assured that you’ll not only be investing in an A-rated product but also a boiler that can automatically reduce itself to just 20% of its maximum output when you need less heat. As a result, you’ll save more energy and your bills will be lower.

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

The Vaillant ecoFIT Pure Regular offers everything you would expect and more. User controls include an LED display, pressure gauge, reset button and hot water and central heating temperature switches. It’s designed to be flexible and comes with a rear flue option so that you can choose where the boiler is installed. The boiler also has a high-spec aluminium heat exchanger for longevity and to help cut the cost of your energy bills. What’s more, you can use the boiler with Vaillant’s optional vSMART app-based control that lets you monitor and manage your heating on the go.

How long is the Warranty on this Boiler?

This gas boiler comes with a 2-year parts and labour warranty as standard. You may be able to upgrade the warranty to 7 or 10 years when you choose a Vaillant Advance installer to fit the boiler.
