Product Description

The Vaillant ecoTEC plus 618 is a condensing system boiler that could help to reduce your energy bills.

How efficient is the ecoTEC Plus 618?

The ecoTEC Plus 618 has a seasonal space heating efficiency of 93% which means that it converts almost all of the fuel into usable energy. As it’s able to perform so efficiently, it has an ErP A-rating for heat.

Is the output rating suitable for my home?

This is an ideal heating system for homes with around 15 radiators.

Are any other options available in the Vaillant ecoTEC Plus range?

The Vaillant ecoTEC Plus range of boilers includes no shortage of option as in addition to multiple system boilers there are also combi and regular boilers too.

If you need a system boiler with a lower central heating output then 12 kW and 15 kW are also available. Higher outputs from 24 kW to 37 kW can meet the heating demands of larger properties.

Is a system boiler suitable for my home?

Installed alongside a hot water cylinder, a system boiler can meet higher demands for domestic hot water in properties with multiple bathrooms. This means that additional space is needed for the installation of the cylinder but, unlike with regular boilers, no tanks are needed in the loft.

How long is the warranty period?

You’ll be well covered after the installation of an ecoTEC Plus boiler as they come with a standard 5 year warranty that can be extended to 7-10 years if installed by a Vaillant Advance Installer.

What are the key features of the ecoTEC Plus 618?

This boiler has been designed with efficiency in mind and the advanced modulation and flame lift detection system help to keep energy usage to a minimum. An efficient energy system will help to keep your energy bills to an absolute minimum.

And for properties that aren’t connected to the gas network, an LPG model is available.

How big is the ecoTEC Plus 618?

This boiler has been designed for wall-mounted installation and can be hidden away in a kitchen cupboard thanks to compact dimensions of 720x440x340mm (HxWxD).
