Expansion vessel for domestic hot water, 12 l, hanging
The product is a high‑quality expansion vessel for domestic hot water systems, designed for wall mounting and stable operation in demanding installations. It balances pressure in the potable water circuit, protecting pipes, fittings and appliances during daily use.
The vessel operates safely at a maximum pressure of 10 bar, with a factory pre‑charge of 1.5 bar, so it fits typical questions about expansion vessel pressure settings in DHW systems. The working temperature range from -10°C to +100°C supports both cold start conditions and high‑temperature operation in modern hot water installations.
The deep‑drawn steel tank offers robust mechanical strength, while the replaceable EPDM membrane separates water from the air chamber and extends service life, because only the worn diaphragm needs replacement. The standard version comes in blue RAL 5015, and the M2 variant in white RAL 9010, which helps match the vessel to surrounding equipment.
This wall‑hung DHW expansion vessel is a reliable choice for anyone planning a domestic hot water expansion tank and looking for a durable, serviceable component that stabilizes system pressure and supports long‑term, trouble‑free operation.
