The Vaillant ecoFIT Pure 415 is a highly adaptable 15kW regular heat-only gas boiler engineered to provide maximum installation flexibility for complex domestic heating systems. Featuring an advanced, high-specification aluminium heat exchanger, this appliance ensures exceptional thermal efficiency, longevity, and reduced energy consumption across its operational lifespan. The unit is designed with an intelligent 4-sided cooling and water agitation system surrounding the heat exchanger, significantly reducing thermal stress to guarantee longer life reliability. Offering an ErP A rating and up to 94% efficiency, it is an optimal heat source for both modernised properties and new build construction.

Measuring just 602mm x 375mm x 295mm, the ultra-compact footprint allows for straightforward integration into standard kitchen cupboards. Installers benefit heavily from the choice of top and rear concentric flue options, alongside an industry-leading maximum flue length of up to 10 metres, accommodating even the most challenging architectural layouts. Boasting a Quiet Mark approval for its ultra-quiet operational noise, the boiler also incorporates an automatic purging assistance program to simplify the commissioning process. The clear LED display ensures fault codes are highly visible even in dimly lit airing cupboards or utility spaces.
