Flat expansion vessel for central heating, 12 l, rectangular
The flat expansion vessel for central heating is designed to stabilize pressure in closed heating systems and protect key components from overload. Its compact, rectangular form with a 12-litre capacity fits neatly into modern boiler rooms and technical spaces.
The integrated air chamber is factory-set to a pre-charge pressure of 1.5 bar, so the vessel works reliably with typical domestic heating installations. Operating temperatures from -10°C to +90°C support both low-temperature and standard systems, while a maximum working pressure of 3 bar suits most residential boilers and heat sources.
The expansion tank is made of deep-drawn steel, giving the body high mechanical strength and resistance to deformation during pressure fluctuations. An SBR membrane separates water from the air chamber, extending service life and reducing the risk of corrosion inside the vessel.
This 12-litre heating expansion tank is a practical choice for installers and homeowners looking for a durable, space-saving solution for pressure control in central heating systems.
