Flat expansion vessel for central heating, 10 l, round
The flat expansion vessel for central heating is a compact solution for stabilising pressure in closed heating systems. Its round shape and 10-litre capacity suit small and medium domestic installations where reliable pressure control matters every day.
The pre-charged air chamber set to 1.5 bar supports correct system operation and helps maintain stable working conditions. The vessel is designed for a maximum working pressure of 3 bar, so it fits typical residential heating systems. A working temperature range from -10°C to +90°C makes the expansion tank suitable for both low-temperature and standard hot water circuits.
The deep-drawn steel body offers high mechanical strength and resistance to deformation during pressure changes. Inside, an SBR membrane separates water from the air chamber, supporting long-term tightness and reducing the risk of corrosion. The flat design simplifies placement in narrow technical spaces, behind casings or near the boiler.
This flat expansion vessel is a practical choice for installers and homeowners who expect durable construction, stable heating system pressure and easy integration with modern central heating installations.
