The product is a robust expansion vessel for domestic hot water systems, designed to stabilise pressure and protect the installation. Its free‑standing design suits technical rooms where a reliable hot water buffer is required.
The vessel operates safely at working pressures up to 10 bar, so it performs well in typical residential and small commercial systems. A factory‑set air chamber with a pre‑charge of 1.5 bar helps users answer the common question about expansion vessel pressure settings for DHW installations. The working temperature range from -10°C to +100°C supports both cold start‑ups and high‑temperature operation.
The deep‑drawn steel tank forms a durable, deformation‑resistant body, while the replaceable EPDM membrane separates water from the air chamber and supports hygienic operation of the DHW expansion vessel. The blue RAL 5015 finish gives the installation a clear technical look and makes the vessel easy to identify among other components.
This standing hot water expansion vessel is a dependable choice for anyone planning a domestic hot water tank installation and looking for stable pressure control and long service life.
