This Vaillant ecoFIT pure 830 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 22mm filter protection kit (Vaillant Advance), you significantly speed up the installation process and ensure long-term system protection right out of the box.
Therefore, this combination boiler works perfectly for medium to large-sized homes, typically with up to two bathrooms and 10 to 20 radiators. Additionally, it easily handles higher daily domestic demands, delivering a continuous hot water flow rate of 12.2 to 12.4 litres per minute.
The boiler features a robust construction, incorporating a high-specification, automotive-grade aluminium heat exchanger with 4-sided cooling to extend its lifetime. Moreover, the accessible internal layout allows all components to be maintained or replaced directly 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 quiet operation at just 51dB.
