What's Included
The Vaillant ecoFIT Sustain 630 Gas System Boiler is a powerful yet compact heating solution designed for homes that require reliable performance and flexible installation options. With its cupboard-fit design and efficient operation, it provides strong heating output while maintaining a small footprint that suits modern properties.
Part of Vaillant’s ecoFIT Sustain range, this model has been developed for the specification market, offering dependable engineering, durable components and efficient performance for a wide variety of installations.
Powerful Heating in a Compact Boiler
With a 30kW output, the ecoFIT Sustain 630 is ideal for homes with higher heating demand when paired with a separate hot water cylinder. Despite its strong performance, the boiler maintains a compact cupboard-fit design with dimensions of 702mm x 390mm x 295mm, allowing it to be installed neatly in kitchens, utility rooms or airing cupboards.
A high-quality aluminium heat exchanger provides efficient heat transfer while remaining lightweight and durable, helping ensure long-term reliability and easier servicing.
The boiler also achieves up to 89.3% efficiency (SAP 2009), helping reduce energy consumption and running costs.
Flexible Installation Options
The ecoFIT Sustain 630 offers flexible siting thanks to top and rear flue options, allowing installers to position the boiler in a wide variety of locations within the home.
Its compact footprint and low lift weight help make installation easier, particularly when replacing older boilers or working in confined spaces.
These gas boilers are also compatible with Vaillant’s full range of flue systems and intelligent heating controls, allowing systems to be tailored to suit the property’s heating requirements.
Efficient and Intelligent Operation
The ecoFIT Sustain 630 includes several advanced components designed to improve system efficiency. A fully modulating low NOx burner and fan help optimise combustion while reducing emissions.
The boiler also features a high-efficiency Grundfos pump, which automatically adjusts its output to match heating demand while using less energy.
A patented condensate trap with safety backup simplifies installation and provides additional protection during operation.
Built for Long-Term Reliability
Vaillant has designed the ecoFIT Sustain range with durability in mind. The patented four-sided cooling system helps reduce stress on internal components, which can extend the lifespan of the boiler and minimise maintenance costs.
A familiar Vaillant diagnostic display provides clear system information, helping engineers quickly identify any issues and carry out servicing efficiently.
