Expansion vessel for central heating, 500 l, standing
The product is a floor-standing expansion vessel designed for closed central heating systems, stabilising pressure and protecting the installation against overload. Its compact, vertical form fits well into boiler rooms and technical spaces, supporting reliable operation of modern heating equipment.
The pre-charged air chamber set to 1.5 bar helps maintain correct system pressure, an important aspect when selecting the right expansion tank pressure for heating installations. The vessel operates safely at working pressures up to 8 bar, and the wide temperature range from -10°C to +100°C suits both low-temperature and high-temperature heating systems.
The deep-drawn steel tank offers high mechanical strength and resistance to deformation during pressure fluctuations. Inside, a replaceable EPDM membrane separates water from the air chamber, extending service life and enabling maintenance without replacing the entire vessel. The red RAL 3000 finish gives the expansion vessel a clear, technical look that matches standard heating components.
This standing expansion vessel for central heating is a practical choice for installers and investors who expect stable pressure control, durable materials and easy servicing in domestic and small commercial heating systems.
