The flat expansion vessel for central heating is a compact solution for stabilising pressure in closed heating systems. With a round, space‑saving shape and a capacity of 12 litres, it suits modern domestic installations that require reliable pressure control and consistent system performance.
This 12 l expansion tank operates within a working temperature range from -10°C to +90°C, so it copes well with typical seasonal conditions. The pre‑charged air chamber set to 1.5 bar supports correct system start‑up, while the maximum working pressure of 3 bar fits standard residential heating circuits and helps protect components from overload.
The vessel is made of deep‑drawn steel, giving the body high mechanical strength and resistance to deformation during operation. Inside, an SBR membrane separates water from the air chamber, supporting long‑term tightness and stable parameters. The flat, round design integrates neatly with wall‑mounted or boiler‑adjacent installations.
This flat expansion vessel is a practical choice for anyone upgrading a central heating system and looking for a durable, technically refined component that supports safe and efficient daily operation.
