With Vaillant’s advanced technology, this 20kW system boiler delivers outstanding efficiency, reducing energy consumption while ensuring consistent warmth.

What is a System Boiler?
A system boiler integrates a sealed heating system with a separate hot water cylinder, providing strong water pressure and consistent heating. Unlike combi boilers, it efficiently stores hot water, making it ideal for homes with multiple bathrooms. System boilers connect directly to the mains water supply, eliminating the need for a loft tank, ensuring reliable performance and space-saving installation.
