The flat expansion vessel for central heating is a compact solution for stabilising pressure in closed heating systems. Its round, space‑saving design with an 8‑litre capacity suits modern boiler rooms and small technical spaces where every centimetre matters.
The integrated air chamber is factory‑set to a pre‑charge pressure of 1.5 bar, so the vessel works reliably in typical domestic installations. Operating temperatures from -10°C to +90°C support both low‑temperature and standard heating systems, while a maximum working pressure of 3 bar fits most residential boiler specifications and answers common questions about the correct expansion tank pressure.
The vessel is made from deep‑drawn steel, giving the body high mechanical strength and resistance to deformation during pressure changes. Inside, an SBR membrane separates water from the air chamber, which extends service life and keeps system performance stable over time. The flat, round shape also simplifies positioning during installation next to the boiler or on the wall.
This flat expansion tank for heating systems is a practical choice for installers and homeowners looking for a durable, pressure‑stable component that supports safe, efficient operation of the entire central heating installation.
