## Summary description

Standing enamelled storage tank Biawar MEGA, model BA-ST 9022-2FE, with 220‑litre capacity and two internal heat exchangers. Designed for hot water storage in heating and domestic hot water systems, it provides separation between primary heating circuit and potable water, supports integration with boilers, heat pumps or solar systems and enables efficient heat transfer and stratification.

## Long description

Standing enamelled storage tank Biawar MEGA BA-ST 9022-2FE with 220 litre capacity is designed to store hot water for heating and domestic hot water systems. The unit incorporates two internal heat exchangers that allow connection of a primary heat source and an auxiliary source such as a solar circuit, boiler or heat pump. The enamelled inner surface reduces corrosion risk and supports hygienic storage while internal stratification improves heat availability at different temperatures.
Advantages
The tank offers compact standing installation and a moderate capacity suitable for small to medium residential systems. Two separate heat exchangers provide flexible integration options for multiple heat sources and enable simultaneous heat charging and recovery. The enamel coating protects the inner surface and contributes to long service life when used with appropriate corrosion protection and water treatment. Internal design supports thermal stratification which can increase system efficiency and reliable delivery of domestic hot water.
Suitable for
 Residential heating systems combined with a boiler or heat pump
 Domestic hot water storage for small to medium households
 Systems that integrate solar thermal collectors as an auxiliary heat source
 Installations requiring separation between primary circuit and potable water
When it may not be suitable
This 220 L standing tank may not be adequate for large households with high hot water demand or for commercial installations that require larger storage volumes. It may also be unsuitable where stainless steel or tank materials with specific approvals are required instead of enamel for certain water qualities or regulatory environments.
Key specifications
 Storage volume: 220 litres
 Number of heat exchangers: two internal coils
 Inner surface finish: enamelled coating for corrosion resistance
 Mounting type: standing/vertical installation
 Intended use: hot water storage for heating and domestic hot water systems
 Supports thermal stratification to optimise temperature layers
How to use
Install the tank in a frost-free, ventilated location on a level surface suitable for the unit weight when filled. Connect the primary and secondary circuits to the designated heat exchanger ports following the system schematic and local plumbing codes. Use appropriate flow controls, safety valves and temperature sensors as required by the overall heating system design. Commission the tank by filling, venting air from the heat exchangers and performing a pressure and leak test before regular operation.
What to consider before purchase
 Calculate household hot water and heating storage needs to verify that 220 L capacity is sufficient
 Verify compatibility of the heat exchanger connections with your boiler, heat pump or solar system
 Check available installation space and ensure vertical standing mounting is possible
 Confirm water quality and whether enamel coating is appropriate or if alternative materials are preferred
Usage recommendations
For best performance, integrate the tank with appropriate controls to prioritise heat source usage and maintain recommended maintenance: regularly inspect anode (if fitted), monitor water quality, and follow manufacturer guidelines for pressure relief and safety device settings.
