Suspended storage tank Sunsystem PSM100, 100 L capacity - wall-mounted buffer tank

Suspended storage tank Sunsystem PSM100 is a 100-litre wall-mounted buffer tank designed for water or heat-transfer fluids. Its compact suspended design saves floor space and fits residential and small commercial heating or solar systems. The tank provides short-term storage to stabilize system temperature, reduce pump cycling and improve circulation when integrated with boilers, heat pumps or solar collectors.

Advantages

The Sunsystem PSM100 offers a compact wall-mounted format that simplifies installation in spaces with limited floor area. Constructed for corrosion resistance and thermal efficiency, the buffer tank reduces wear on circulation components by decreasing frequent pump starts. Its 100 L capacity supports effective thermal buffering to smooth temperature fluctuations and enable more consistent heat delivery across connected circuits.

Suitable for

• Residential heating systems requiring hydraulic buffering
• Small commercial premises with limited installation space
• Integration with gas or electric boilers to reduce cycling
• Solar thermal installations as a short-term storage buffer
• Heat pump systems needing improved circulation stability

Key specifications

• Nominal volume: 100 litres
• Mounting type: wall-mounted (suspended)
• Intended medium: potable water or heat-transfer fluids
• Primary purpose: buffer/stabilization and short-term storage
• Installation environment: indoor residential or small commercial

How to use

Install the Sunsystem PSM100 on a suitably reinforced wall using appropriate fixings and according to local plumbing and mounting regulations. Connect the inlet and outlet to the system hydraulic circuit ensuring correct flow direction and use compatible pipework and fittings for the chosen heat-transfer fluid. Commission the buffer tank with system flushing and filling procedures, bleed trapped air, check for leaks and confirm pump and control settings to accommodate the additional buffer volume.

Usage recommendations

Position the suspended buffer tank where it is accessible for maintenance but out of the way of everyday operations. Use corrosion-compatible fluids and follow the manufacturer’s guidance on operating pressures and temperatures. For systems with closed-loop antifreeze or glycol mixtures, ensure materials and seals are compatible and perform periodic inspections for leaks and thermal performance.
