Expansion vessel for central heating, 80 l, standing
The free-standing expansion vessel for central heating installations stabilises pressure in the system and protects key components from overload. It is designed for closed heating circuits and finished in a durable red RAL 3000 coating that stands out clearly in the boiler room and supports easy identification during service.
The pre-pressurised air chamber set to 1.5 bar supports correct operation in typical domestic heating systems and helps answer common questions about the right expansion tank pressure. The vessel works in a wide operating temperature range from -10°C to +100°C, so it copes well with both cold start-up and high-temperature heating cycles.
The deep-drawn steel tank offers high mechanical strength and resistance to deformation under pressure. Inside, a replaceable EPDM membrane separates the water from the air chamber; the material is resistant to ageing and frequent temperature changes, and the option of replacement extends the service life of the entire vessel.
The maximum working pressure of 8 bar suits most modern central heating installations and supports safe, long-term operation of boilers, pumps and radiators. This expansion vessel is a reliable choice for installers and homeowners who expect stable system performance and low-maintenance operation.
