Hand-built in Vaillant’s award-winning Derbyshire manufacturing plant, it delivers efficiency, smart control compatibility, and ultra-quiet operation—all in a cupboard-size unit.

Why Choose a System Boiler?

A system boiler is ideal for homes with multiple bathrooms, providing strong water pressure and a continuous hot water supply. It requires a hot water storage cylinder, ensuring multiple taps and showers can run simultaneously without pressure loss. Unlike conventional boilers, it doesn’t need a separate cold water tank, making installation more efficient.

Features:

• Compact design – Small enough to fit in a standard kitchen cupboard.
• Quiet Mark certified – One of the quietest boilers in its category.
• High-performance aluminium heat exchanger – Delivers outstanding efficiency with low energy consumption.
• Smart energy-saving technology – Modulates down to 20% of maximum output, reducing energy waste and lowering bills.
• Compatible with vSMART™ – Enables remote heating control via the internet for greater convenience.
• Flexible installation – Rear flue option provides more placement choices.
• Total system solution – Works seamlessly with Vaillant cylinders, controls, and accessories.
• ErP ‘A’ rated – High efficiency for both heating and hot water.
