What's Included

Part of Vaillant’s ecoFIT Sustain range, it offers an excellent size-to-output ratio, making it ideal for homes that need higher hot water demand without sacrificing valuable installation space.

Powerful Performance in a Compact Design

With a 30kW output, the ecoFIT Sustain 830 is well suited to homes with higher heating and hot water requirements. Despite its strong performance, the boiler maintains a compact cupboard-fit design, allowing it to be installed neatly in kitchen cupboards or other confined spaces.

These has boilers use a high-quality aluminium heat exchanger, providing efficient heat transfer while remaining lightweight and durable. This construction also helps make installation and servicing easier.

The system achieves up to 89.3% efficiency (SAP 2010), helping to reduce energy consumption and keep running costs lower.

Flexible Installation Options

The ecoFIT Sustain 830 offers flexible siting thanks to its top and rear flue options, allowing installers to position the boiler in a variety of locations within the home.

It is also compatible with Vaillant’s full range of flue systems and controls, providing flexibility when designing efficient heating systems.

A patented condensate trap simplifies installation while providing an additional safety backup for long-term reliability.

Smart, Efficient Operation

The ecoFIT Sustain 830 is designed to deliver efficient performance through intelligent system components. A fully modulating low NOx burner and fan help optimise energy use while maintaining reliable heating output.

The boiler also features a high-efficiency Grundfos pump, which modulates automatically to balance system demand while using less energy.

A 1:4 modulation range allows the boiler to adjust its output based on heating demand, helping to maintain efficient operation throughout the year.

Built for Reliability and Easy Maintenance

Vaillant’s patented four-sided cooling system helps reduce stress on internal components, which can extend the lifespan of the boiler and reduce maintenance costs.

A clear Vaillant diagnostic display provides easy access to system information, helping engineers quickly identify and resolve any servicing requirements.

The boiler also includes two-stage frost protection, helping ensure reliable operation during colder weather.
