Compact Design with Reliable Performance
With a 15kW output, the ecoFIT Sustain 615 is well suited to homes that require efficient heating through a system boiler setup, working alongside a separate hot water cylinder.
Despite its performance, the boiler features a compact cupboard-fit design, allowing it to be installed discreetly in kitchens, utility rooms or airing cupboards without taking up unnecessary space.

Flexible Installation Options
These gas boilers have been designed to provide flexibility during installation. Top and rear flue options allow installers to position the boiler in a variety of locations around the home.
The boiler supports flue lengths of up to 10m with a 60/100 flue system or up to 25m with an 80/125 flue, providing additional freedom when planning installation layouts.
Its lightweight construction and compact footprint also help simplify handling and installation.
Intelligent Controls and Efficient Operation

These controls allow users to manage heating more efficiently, helping reduce energy bills while maintaining comfortable indoor temperatures.
Built for Long-Term Reliability
Vaillant has designed the ecoFIT Sustain range to provide long-lasting reliability. The patented four-sided cooling system helps reduce stress on internal components, which can help extend the lifespan of the boiler and reduce maintenance costs over time.
A clear LED display with familiar Vaillant diagnostics makes the boiler easy to monitor and helps engineers quickly identify any servicing requirements.
The layout of the boiler also allows all key components to be accessed from the front, making servicing and maintenance quicker and easier.
