Sealed heating system

Vaillant product portfolio

A sealed heating system, often called a closed-loop system, operates within a pressurised circuit to deliver efficient and reliable warmth to your home. Unlike open systems, it keeps water completely sealed from the atmosphere. This smart design prevents air from entering, reducing corrosion risks and ensuring long-lasting performance. Treated with antifreeze or inhibitors, the water circulates continuously, while a pressure gauge and expansion vessel regulate natural changes in water volume as it heats and cools. This keeps the pressure consistent and the operation stable.

Closed systems not only save space but also require minimal maintenance, avoiding issues like air bubbles and leaks. With built-in safe pressure control, they provide modern homes with efficient, flexible, and worry-free heating solutions.
