Flat expansion vessel for central heating, 10 l, rectangular
The flat expansion vessel for central heating is designed to stabilise pressure in closed heating systems and protect components from overload. Its compact, rectangular 10-litre design fits neatly into technical rooms and modern boiler setups, supporting efficient and reliable operation of the installation.
The working temperature range from -10°C to +90°C suits typical domestic heating conditions, from cold start-up to high-temperature operation. A pre-charged air chamber set to 1.5 bar helps maintain correct system pressure, while the maximum operating pressure of 3 bar matches most residential heating installations and supports safe performance over time.
The vessel is made of deep-drawn steel, so the tank body remains robust under repeated pressure cycles and thermal changes. Inside, an SBR membrane separates water from the air chamber, reducing the risk of corrosion and extending service life. The flat, rectangular shape also simplifies positioning on walls or in narrow installation spaces.
This flat expansion vessel is a practical choice for anyone upgrading a central heating system and looking for a durable, space-saving pressure tank that supports stable operation and long-term protection of the installation.
