The ecoFIT Sustain 415 incorporates several features designed to maximise efficiency and reduce energy consumption. A fully modulating low NOx burner and fan helps optimise combustion while reducing emissions.
With a modulation range of up to 1:5, the boiler can adjust its output depending on heating demand, helping maintain efficient operation and reduce energy use.
The boiler is also ErP A-rated, helping reduce running costs for homeowners and tenants.
Designed for Easy Installation and Maintenance
The ecoFIT Sustain range has been designed with installers and engineers in mind. Top and rear flue options allow greater flexibility when deciding where to position the boiler.
A patented condensate trap with safety backup simplifies installation and provides additional protection during operation.
These gas boilers also feature familiar Vaillant diagnostics and a clear LCD display, making system information and fault codes easy to read, even when the boiler is installed in less visible locations.
Built for Reliable Year-Round Operation
The ecoFIT Sustain 415 includes two-stage frost protection, helping protect the system during colder weather and maintain reliable performance throughout the year.
Combined with Vaillant’s high-quality components and durable design, this helps ensure dependable heating performance for years to come.
