## Summary description

Standing buffer tank Biawar UKV 20-220 is an unenameled, insulated thermal storage vessel with 220 L capacity. Designed to accumulate and stabilise heating system water, it reduces short-cycling of heat sources and balances supply for boilers, heat pumps or solar installations. The insulated body helps limit heat loss during storage and supports efficient system operation.

## Long description

Standing buffer tank Biawar UKV 20-220 is an unenameled, insulated thermal storage vessel with a usable volume of 220 liters. It is designed to accumulate and stabilise water in central heating systems, reducing short-cycling of heat sources and smoothing the supply from boilers, heat pumps or solar thermal installations. The insulated shell limits heat loss during storage and supports steady operation of connected devices.
Advantages
The tank offers passive thermal storage without internal enamel coating, which is suitable for systems where corrosion protection is provided externally or by system water quality control. Its 220 L capacity provides a buffer that reduces on/off cycles of heat generators, improving runtime stability. External insulation improves energy retention and reduces the need for frequent reheating. The vertical standing design minimises floor footprint while allowing straightforward hydraulic connections.
Suitable for
Domestic and small commercial central heating systems
Integration with boilers to reduce short-cycling
Combined operation with heat pumps to balance load
Solar thermal systems requiring hydraulic storage
Systems using external corrosion protection or treated system water
Key specifications
Nominal volume: 220 L
Construction: unenameled steel vessel with external insulation
Orientation: vertical, standing model
Purpose: hydraulic and thermal buffering for heating circuits
Thermal protection: external insulation to reduce heat loss
How to use
Install the buffer tank on a level, load-bearing surface close to the heat source or hydraulic manifold. Connect supply and return lines according to the system schematic, ensuring proper placement of sensors, safety valves and air vents as required by local regulations. Commission the system by filling, bleeding and pressure-checking the tank and associated piping. Operate the tank as part of the heating circuit to accumulate excess heat and supply it when demand rises, thereby smoothing generator operation.
Usage recommendations
Use water treatment or corrosion inhibitors if the system lacks internal corrosion protection, and follow manufacturer and local installation codes for pressure settings and safety components. Regularly inspect insulation and external connections for damage and maintain system water quality to prolong service life.
