Buffer tank (wall-mounted) Galmet 120 L model 1870-127000 — 120 litres capacity

The Galmet wall-mounted buffer tank with 120 litres capacity is a hydraulic accumulation vessel intended to stabilize heating system operation in residential and light-commercial installations. Designed for vertical wall mounting, this buffer tank stores thermal energy produced by boilers, heat pumps or solar thermal collectors, reducing short cycling and smoothing temperature fluctuations within the heating circuit. The compact design and moderate capacity make it suitable where floor space is limited but a thermal buffer is required to improve system efficiency and comfort.

Advantages

This buffer tank provides a stable thermal reservoir that reduces boiler on/off cycles, which helps extend the service life of prime movers and improves overall system efficiency. Its wall-mounted configuration saves floor space and simplifies integration in basements, utility rooms or plant rooms. The vessel is constructed for reliable hydraulic performance and offers a neutral design compatible with a range of heating sources such as gas or solid fuel boilers, heat pumps and solar thermal systems.

Suitable for

• Reducing boiler cycling in small to medium-sized heating systems
• Integration with heat pumps to balance intermittent output
• Storing solar thermal gains for use during demand periods
• Installations with limited floor space where wall mounting is preferred

Key specifications

• Nominal volume: 120 litres
• Mounting type: wall-mounted, vertical orientation
• Primary function: hydraulic accumulation of thermal energy
• Compatible with: boilers, heat pumps and solar thermal systems
• Typical application: residential and light-commercial heating circuits

How to use

Install the buffer tank on a suitable load-bearing wall using appropriate fixings and clearances as required by local installation standards. Connect the tank hydraulically to the heating circuit so that it receives heat from the source and supplies stored energy to the distribution circuit. Ensure correct hydraulic balancing, appropriate safety devices and air-venting points are fitted in accordance with system design. Commission the system following manufacturer and regulatory guidelines, checking for leaks, proper flow direction and temperature control integration.

Usage recommendations

Size the buffer capacity relative to the heat source and system load to achieve the desired reduction in cycling. Use suitable corrosion protection and water treatment in closed heating systems. Regularly inspect mounting fixings, hydraulic connections and insulation for integrity; perform scheduled maintenance on the entire heating installation to preserve efficient operation.
