This Vaillant ecoFIT pure 825 gas combi boiler pack connects directly to your central heating and domestic hot water systems. Specifically, it provides a highly reliable and efficient method of delivering both space heating and instant hot water from a single, wall-mounted unit. Furthermore, thanks to the included horizontal flue kit and Vaillant Advance system filter, you significantly speed up the installation process and ensure long-term system protection right out of the box.
Therefore, this Vaillant ecoFIT pure 825 works perfectly for small to medium-sized homes or flats, typically with one bathroom and up to 10-15 radiators. Additionally, it easily handles daily domestic demands, delivering a continuous hot water flow rate of 10.4 litres per minute at a 35°C temperature rise.
The boiler features a robust construction, incorporating a high-specification aluminium heat exchanger with 4-sided cooling to extend its lifetime. Moreover, the accessible internal layout allows all components to be maintained from the boiler front. As a result, this reliable build makes it fully compliant with modern energy standards, offering an ErP A-rating at 94% efficiency and ensuring ultra-quiet operation at just 49dB.
Key Features & Benefits:
Complete Boiler Pack: The package comes fully equipped with a standard horizontal flue and a premium Vaillant Advance magnetic filter. Importantly, the filter actively captures circulating magnetite and non-ferrous debris before it enters the boiler. Therefore, it guarantees a safe, fully compliant exhaust setup and maximum long-term protection for your heating network.
Compact Cupboard Fit: The boiler’s space-saving design measures just 700mm x 390mm x 295mm. Consequently, you achieve highly flexible installation options, easily fitting the unit inside standard kitchen cupboards without sacrificing performance.
Durable Aluminium Heat Exchanger: The system includes an advanced aluminium heat exchanger designed with 4-sided cooling and water agitation. For example, when operating daily, this mechanism effectively reduces thermal stress and prevents wear. Ultimately, this allows you to create a long-lasting heating system that operates at up to 94% efficiency.
User-Friendly Control: The front panel features a clear LED display for excellent visibility in dimly lit areas and simple diagnostics. In particular, this interface provides easy access to settings and is fully compatible with Vaillant’s intelligent range of smart controls for energy-efficient system management.
