The EcoTEC Plus 418’s Info….

The EcoTEC Plus 418 is a slightly higher output boiler system than the Vaillant Ecotec 415  but it still delivers great performance with a high output of hot water due to it being a regular boiler system with external tanks supplying the water hot and ready as required.


Let’s look a little further….

Boiler Output and flow rate:


Vaillant Ecotec Plus 418 Regular Boiler Review Compare Boiler Quotes

This boiler, although it can supply a lot of hot water, is only suitable and recommended for a smaller home or apartment, with 1-3 bedrooms and one bathroom. Due to it being a regular boiler, it means that it requires a cold water supply tank in the attic or loft as well as a hot water storage cylinder in an airing cupboard. 

Bear in mind that this means that you will need additional space for these tanks but it does allow for a higher output of hot water compared to a combi. 

Having said this, a combi boiler may be a better choice for a smaller, limited space home as the modern systems offer a high enough output while saving much needed space. 


The heating output is only 18kW which isn’t as high as other systems however the low price of the boiler makes up for this and the fact that it is a regular boiler means it would be powerful enough for the 1-3 bed home. In terms of heating output, it will heat up to 15 radiators simultaneously so you may need to count up how many you have before deciding if this boiler is right for you.

This Vaillant EcoTEC Plus 418 is a slim and stylish boiler with a size of 600x375x316mm. It is 

also lightweight and is designed to fit neatly  inside a standard kitchen cupboard. We’d still suggest measuring your kitchen cupboard to double check as smaller homes can have varying cupboard sizes to accommodate a kitchen in a small space. 



Vaillant Ecotec Plus 418 Regular Boiler Review Compare Boiler QuotesVaillant has a standard 5 year warranty on this system which is quite low compared to other modern manufacturers and systems. We think you’d do better with a system that has more confidence in the quality of their manufacturing such as manufacturers like Viessmann

We say this as we always expect any modern combi boiler manufacturer to offer a 5 year warranty as standard but would actually recommend the companies who offer 10 such as Viessmann. 

Viessmann offers a 10 year standard warranty and if you choose Boiler Central as your boiler installation company, you can get an industry leading 15 year warranty! 



If you have a smaller one to three bedroom apartment or home then this system may seem like it is right for you due to its compact size and efficiency however this is not necessarily the case. 

We think a combi boiler would better suit due to the ease of install, the ease of use, and the far less space required due to no external tanks being needed. The warranty is the other issue at 5 years standard. It’s not bad, but other systems with better output, efficiency, and price have better warranties. 

We would alternatively recommend  the Viessmann Vitodens 050-W system with higher efficiency, a better warranty, and a more reliable over experience with a better stainless steel heat exchanger. This system would be far more reliable and easy to maintain, more affordable and save you money on your bills. 

This model, the Vaillant EcoTEC Plus 418, we’d rank this at a 5/10. Not very good to be honest, but again there are other systems available which are much better and at amore affordable price.


We have the facility to get a custom quote on a suitable boiler for your home but using our specially designed boiler quote calculator. This is through our partner Boiler Central.
