Vaillant ecoTEC Plus System

Vaillant ecoTEC Plus System

The Vaillant ecoTEC Plus System is the brand’s flagship boiler that guarantees to meet the demands of most homes and lifestyles.

Launched in 2015, the ecoTEC Plus System is one of Vaillant’s more popular gas condensing boilers because it comes in a great range of heating outputs and is designed to suit almost any small, medium or large-sized home. In addition to being very reliable, efficient and easy to use, the boiler is extremely quiet and has even been awarded the Quiet Mark accreditation and Which? Best Buy status.

How Much Does this Boiler Cost?

As there are six outputs available including 12kW, 15kW, 18kW, 24kW, 30kW and 37kW, Vaillant ecoTEC Plus System prices range from £780 to £1,370. The higher output options tend to cost more than the lower output models, but this isn’t always the case because prices also vary between different suppliers and installers. To find the most competitive deal, you’ll need to shop around. Also, don’t forget to find out how much the installation is going to cost as this won’t be included in the price of the boiler.

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

This boiler is what’s called a ‘system boiler’ and will require a separate cylinder for storing your hot water. Most people who have a system boiler keep their cylinder in the airing cupboard. System boilers are perfectly suited to homes with more than one bathroom and where hot water demand is greater because they can provide a lot of hot water at once, even though they don’t need additional water tanks in the loft.

Although the Vaillant ecoTEC Plus System is ideal for homes of all sizes, you still need to work out which heat output will meet the needs of your household. To know the right heat output for sure, you will need to get some professional advice from a Gas Safe registered engineer.

Is it a High Efficiency Boiler?

It sure is. The ecoTEC Plus System is Energy Saving Trust endorsed and ErP A-rated for heating and hot water efficiency. It even has the ability to reduce its maximum output to just 16% when it detects that less heat is required, making it a great energy-saving option that should help to cut the cost of your fuel bills. If you want to make your heating system more efficient, you can have the boiler installed with a uniSTOR cylinder. You can even purchase some smart optional controls that also help to reduce your bills, such as the VRC 700 or vSMART app-based heating control.

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

The user controls include an on and off switch, reset button, pressure gauge and heating temperature control, all of which are concealed behind a panel that is situated at the front of the boiler. It also has a clear backlit display and is Quiet Mark approved, making it one of the quietest boilers your money can buy. The ecoTEC Plus System is a natural gas boiler but it can be converted to LPG if your property is off the gas grid. Some of its best features are the built-in installation wizard that allows for hassle-free setup and the stainless steel heat exchanger that enhances boiler efficiency and reliability.

How long is the Warranty on this Boiler?

The ecoTEC Plus System comes with a 5-year parts and labour warranty as standard. If you choose a Vaillant Advance installer to fit the boiler you should be able to extend this guarantee.
