Vaillant ecoTec exclusive Green iQ 627 System Boiler - Review
In today’s review, we’re looking at the Vaillant ecoTec exclusive Green iQ 627 System Boiler. It’s a bit of a mouthful to say but stick with us because this boiler has a lot of great things to offer.
First, let’s provide a quick introduction to Vaillant, the brand behind the boiler. Vaillant is a German boiler manufacturer that has been in the business since 1874. They’re known for their eco-centric heating systems, which are built to the highest standards, with both the consumer and planet in mind. Choose a Vaillant boiler for reliability, great eco-friendly credentials and high levels of efficiency.
Now you know a little more about Vaillant, it’s time to see whether the ecoTec exclusive Green iQ 627 is the right system boiler for your home.
Will the Vaillant ecoTec 627 be suitable for my home?
The Vaillant ecoTec 627 system boiler is designed for large, semi-detached and detached houses with two or more bathrooms. With a 27kW central heating output, it can easily power 15 to 20 radiators. Counting up your radiators is the best way to determine the output you need, so always do a quick check around before buying a boiler.
One of the advantages of installing a system boiler like the ecoTec 627 is that you can benefit from a constant supply of hot water to a number of taps simultaneously. This makes it ideal for busy households, with multiple bathrooms. System boilers require a cylinder to store hot water, but there is no need for a tank in the loft, freeing up significant space.
The ecoTec exclusive is the first boiler to be built with eco-friendly and 85% recyclable materials. It can work with solar water heating systems and heat pumps, which will not only reduce your carbon footprint but may also result in significantly lower heating bills.
Although the ecoTec exclusive Green iQ 627 is only available with a 27kW output, it’s worth noting that Vaillant also has system boilers with higher outputs for those with larger domestic properties and a greater number of radiators.
If you’d like to compare the Vaillant ecoTec 627 with a boiler from another brand, we recommend looking at the Worcester Bosch Greenstar 27i System boiler, which also has a 27kW output. It is designed to fit inside a kitchen cupboard (though we suggest measuring to check first), and may be a better option if you lack space in your home.
Vaillant ecoTec Exclusive Green iQ 627 Controls
The Vaillant green iQ system boiler has a control panel, located under the front flap, providing information such as the current heating flow temperature, the operating mode and any fault codes. There are also option buttons and controls for setting the hot water and heating flow temperatures.
Today, all boilers, including the Vaillant ecoTec exclusive, must comply with Boiler Plus (industry legislation that came into play back in April 2018.) The Boiler Plus regulations stipulate the minimum efficiency levels a boiler must deliver, along with the need for both time and temperature controls.
To ensure your boiler is compliant, we suggest using a smart thermostat. They offer great benefits for you too, as they can help optimise your boiler’s performance, resulting in greater efficiency and lower running costs. Here are a few suggestions:
Vaillant VRC 700 heating control – This intelligent thermostat offers a range of flexible controls that allow you to maximise the performance of your boiler and achieve the temperatures you need, with the least energy usage possible. It has a number of useful features including weather compensation and holiday programmes.
Vaillant vSMART™ - The Vaillant 627 also works with the self learning vSMART™ thermostat and smartphone app. Take control of your heating and hot water temperatures from any location.
Nest and Hive – Two other high-profile smart thermostats that are compatible with this system boiler. Both have their own apps, so you can control your heating system no matter where you are.
Honeywell Lyric T6 Smart Thermostat – Fancy getting a smart thermostat for free? Choose Hometree to install your Vaillant ecoTec 627 system boiler and we’ll throw in a fully compatible, Honeywell Lyric T6 Smart Thermostat. Like the other options, it has a handy smartphone app, for improved boiler performance and extensive control over your heating system.
Vaillant ecoTec exclusive 627 size
Measuring 720x440x338mm, the Vaillant 627 is probably a little too large for a standard size kitchen cupboard, unless you build something custom.
If you need a smaller model, take a look at Vaillant’s ecoFit Pure system boilers, which are more compact, measuring 700x390x295.

Verdict - Is the Vaillant ecoTec 627 the best boiler for your home?
The ecoTec exclusive green iQ 627 will make an excellent choice for large family homes, looking to replace an old, inefficient system boiler. Its ability to heat 15-20 radiators and supply hot water to multiple taps is a huge selling point for big, busy households.
