Expansion vessel for domestic hot water, 35 l, hanging
The product is a high‑quality expansion vessel for domestic hot water systems, designed for wall mounting and stable operation in demanding conditions. It supports safe pressure control in closed potable water installations and fits both new systems and modernisations.
The vessel operates with a pre‑set air chamber pressure of 1.5 bar, giving a clear answer to typical questions about the required pressure in a DHW expansion tank. A maximum working pressure of 10 bar suits standard residential and small commercial installations, while the working temperature range from -10°C to +100°C covers both cold start‑ups and high‑temperature operation.
The deep‑drawn steel body provides robust mechanical strength, and the replaceable EPDM membrane separates water from the air chamber, extending service life and simplifying maintenance. The blue RAL 5015 finish, and for the M2 version the white RAL 9010 coating, integrate well with common boiler room and utility room colour schemes.
This wall‑hung DHW expansion vessel is a reliable choice for installers and homeowners who expect stable pressure, long‑term durability and an installation element matched to modern hot water systems.
