The product is a high‑quality expansion vessel designed for domestic hot water systems, stabilising pressure and protecting the installation from overloads. It is dedicated to potable water and fits both new systems and modernisation projects where reliable pressure control is required.
The vessel operates safely at working pressures up to 10 bar, so it copes well with typical residential installations. A factory pre‑charge of 1.5 bar helps answer the common question about the right expansion vessel pressure for hot water systems and simplifies initial setup for installers. The working temperature range from -10°C to +100°C supports year‑round operation, including higher temperatures in storage water heaters.
The deep‑drawn steel tank forms a robust, deformation‑resistant body, while the replaceable EPDM membrane separates water from the air chamber and extends service life. The wall‑mounted design saves floor space and integrates neatly into technical rooms. The standard blue RAL 5015 finish, and for the M2 version white RAL 9010, blends well with typical installation components.
This domestic hot water expansion vessel is a practical choice for anyone looking for a durable, serviceable solution with clear installation pressure parameters and dependable protection of the entire hot water system.
