Buffer Tank Afriso ABT 160 (model 6816000) – uninsulated hot water storage capacity 160 L

The Afriso ABT 160 buffer tank is an uninsulated hot water storage vessel with a nominal capacity of 160 litres designed for integration into central heating systems. It is intended to accumulate and stabilise heating system water, reducing short-cycling of heat sources and helping to smooth load variations. Suited for residential and light-commercial installations, the tank works with boilers, heat pumps and solar thermal systems to improve system response and provide a local buffer of stored thermal energy.

Advantages

The uninsulated construction offers flexibility for sites where insulation is applied on-site or where the tank is installed within an already conditioned plant room. A 160-litre nominal capacity provides sufficient inertia for many domestic and small commercial heating circuits, helping to reduce cycling of heat generators and stabilise supply temperature. The tank is designed for straightforward hydraulic integration and to operate with common heating system components without introducing complex controls.

Suitable for

• Domestic central heating systems with boilers
• Heat pump installations requiring thermal buffering
• Solar thermal systems needing storage and load smoothing
• Light-commercial heating circuits and plant rooms

Key specifications

• Nominal storage volume: 160 litres
• Type: uninsulated hot water buffer tank
• Application: accumulation and stabilization of heating system water
• Compatibility: suitable for use with boilers, heat pumps and solar thermal systems
• Installation: intended for integration into central heating installations in residential or light-commercial settings

How to use

Install the buffer tank according to local regulations and the system designer's hydraulic layout, ensuring correct connection of flow and return lines and fitting of necessary safety and control devices such as pressure relief valves, expansion vessels and temperature sensors. Because the unit is uninsulated, fit external insulation if required to meet thermal performance or site-specific heat loss limits. Commission the system with proper purging to remove air and verify temperatures and pressures before regular operation.

Usage recommendations

Place the tank in an accessible plant room or service area that allows for connection, maintenance and potential addition of insulation. Coordinate tank size and piping arrangement with the heating source capacity and system hydraulics to maximise the buffering effect and reduce short-cycling of boilers or heat pumps.
