Vaillant ecoFit Pure 418 Regular Boiler – Review

Next, in our series of Vaillant boiler reviews, we have the ecoFit Pure 418 Regular boiler. It may be small, but it is mighty. Read on to find out everything you need to know about the Vaillant ecoFit Pure 418 to help you decide whether it’s the right regular boiler for your home.

Before we get down to the finer details, let’s first tell you a little a bit about the leading German manufacturer, Vaillant. For those who don’t know, this company has been around for a very long time. We’re talking 1874. Yes, that long! Over the years, Vaillant has built up a reputation for greatness. They’re world-renowned innovators and one of the go-to brands for premium quality heating systems. Choose Vaillant and have the peace of mind that you are investing in a superior quality boiler.

Now you’re clued up on Vaillant, let’s move on to the ecoFit Pure, a regular boiler offering powerful performance and compact design.

Will the Vaillant ecoFit Pure 418 be suitable for my home?

The Vaillant ecoFit Pure 418 is designed for big family homes with multiple bathrooms. Unlike combi boilers, regular boilers require a hot water cylinder (usually stored in an airing cupboard) and a loft tank. The Vaillant ecoFit Pure is compatible with a wide range of hot water cylinders. One option is the uniSTOR range of hot water cylinders. These are available as slimline, pre-plumbed and standard. The 418 is a great choice for those looking to replace an inefficient regular boiler.

One of the benefits of a regular boiler, like the Vaillant ecoFit Pure, is that you will benefit from constant hot water. The Vaillant Pure 418 will supply hot water to a number of taps simultaneously, making them ideal for busy homes. It also has a central heating output of 18kW and will comfortably heat between 10-15 radiators.

The high-spec aluminium boiler is designed to stand the test of time, whilst helping you keep your energy bills to a minimum. It can also be used in homes with solar and heat pump systems for a lower carbon footprint and reduced energy costs.

If you are looking for a compact regular boiler, with a higher output, the Vaillant ecoFit Pure is also available with 25kW, 30kW and 35kW outputs. As an alternative to compare the ecoFit with, take a look at the Worcester Bosch Greenstar 18Ri. This boiler model also has a compact design and is available with an 18kW output.

Vaillant ecoFit Pure Regular Controls

In terms of controls, the Vaillant ecoFit has everything you would expect, including an LED display, pressure gauge, reset button and switches for both the hot water and central heating temperature. These temperature controls mean it is fully compliant with the Boiler Plus regulations, introduced back in April 2018.

It’s useful to know that the Vaillant 418 boiler is also compatible with the brand’s vSMART smart thermostat and smartphone app, along with the popular Nest and Hive smart thermostats. All of these smart devices give you the freedom to monitor and control your heating and hot water, at any time, from any location.

ecoFit Pure 418 Regular Size

One of the reasons the Vaillant ecoFit 418 is so popular is its compact size. At 602 x 375 x 295mm, it is small enough to fit in your average kitchen cupboard. However, since kitchen cupboards come in all forms and sizes, we recommend you double-check whether this model could fit yours. It’s also got a flexible rear flue option, which gives you a greater choice of where to install your boiler. If space comea at a premium in your home, the ecoFit Pure will certainly tick the boxes.

Vaillant ecoFit Pure 418 Regular Warranty

Most boilers, like the Vaillant ecoFit 418, come with a 5-year warranty as standard. With Hometree, you’ll receive a 5-year warranty for free, which can be doubled up to 10 years for a small extra charge.

ecoFit Pure 418 Energy Efficiency

Today all boilers are required to offer high levels of energy efficiency. We’re pleased to tell you that the Vaillant ecoFit 418 has a great ErP rating (previously known as SEDBUK) of 89%. If you’re not sure what that means, ErP stands for Energy-related Products and is the system used to rate the energy efficiency of boilers. An 89% ErP would give the ecoFit Pure 418 an A rating overall. This is good news because if you swap your old boiler for a new A-rated boiler, you should make savings on your energy bills.

Verdict – Is the Vaillant ecoFit Pure 418 Regular the best boiler for your home?

If you are looking to replace an existing regular boiler system that is old and inefficient, the Vaillant ecoFit Pure 418 will make an excellent choice. If you think about it, it ticks all the boxes. It’s small and lightweight, so you can install it in your kitchen cupboard. It’s powerful enough to heat 10-15 radiators, making it great for big homes. And it creates instant hot water, which is a huge benefit for busy people, who don’t have time to wait for others to finish running the tap!
