Expansion vessel for domestic hot water, 100 l, standing
The standing expansion vessel for domestic hot water is designed to stabilise pressure in potable water installations and protect system components. Its compact, vertical form fits well in technical rooms, while the blue RAL 5015 finish gives the tank a clean, professional look.
The pre-charged air chamber set to 1.5 bar supports correct operation of the DHW expansion tank and helps answer the common question about expansion vessel pressure in hot water systems. A maximum working pressure of 10 bar suits typical residential and light commercial installations, and the operating temperature range from -10°C to +100°C covers both cold start-up and high-temperature domestic hot water.
The vessel is made of deep-drawn steel, which increases structural strength and resistance to deformation under load. Inside, a replaceable EPDM membrane separates water from the air chamber, maintaining stable performance over time and enabling straightforward servicing instead of replacing the entire tank.
This standing hot water expansion vessel is a solid choice for installers and investors who expect reliable pressure control, long service life and easy maintenance in domestic hot water systems.
