The product is a robust expansion vessel for domestic hot water systems, designed to stabilise pressure and protect the installation. The 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 copes well with typical household and small commercial systems. A factory pre‑charge of 1.5 bar supports correct pressure settings for users wondering what pressure an expansion vessel for DHW should have. The working temperature range from -10°C to +100°C fits both cold start conditions and high hot‑water loads.
The deep‑drawn steel tank forms a durable, deformation‑resistant body, while the replaceable EPDM membrane separates water from the air chamber and extends service life. When the membrane wears out, replacement restores full functionality without changing the entire vessel, which reduces maintenance costs over time.
The blue RAL 5015 finish gives the expansion vessel a clear technical look and helps identify it quickly among other installation components. It is a solid choice for anyone planning or upgrading a domestic hot water expansion tank and looking for dependable pressure control in everyday use.
