## Long description

Suspended storage tank Sunsystem PSM50 is a compact 50 L buffer vessel designed for closed heating and solar systems. The wall-mounted tank provides hydraulic separation between primary and secondary circuits, stores thermal energy and helps reduce short-cycling of heat sources. Intended for small residential installations, the unit supports integration with boilers, heat pumps and solar thermal loops, offering a space-saving solution that enhances system stability and heat exchange efficiency.
Advantages
The Sunsystem PSM50 tank combines compact dimensions with 50 litres of usable storage capacity, allowing installation in limited spaces such as boiler rooms or utility closets. By providing hydraulic separation, it reduces pressure fluctuations and protects circulating pumps and control valves. Wall-mounted design simplifies mounting and saves floor area, while internal corrosion protection and proven construction improve long-term reliability and reduce maintenance needs.
Suitable for
 Small residential heating systems with a single boiler or heat pump
 Domestic solar thermal installations and solar loop buffering
 Systems requiring hydraulic separation and stabilization of pump operation
