## Long description

Biawar Wymiennik Mega W-E-220.81 is a 220‑liter vertical water heater with an integrated spiral coil heat exchanger intended for indirect heating. The unit stores domestic hot water and is designed to work with external heat sources such as gas, oil or solid fuel boilers and solar thermal systems. Its compact vertical layout and corrosion‑resistant internal materials make it suitable for utility rooms and technical spaces where reliable hot water storage and efficient heat transfer are required.
Advantages
The spiral coil exchanger provides efficient indirect heat transfer and rapid recovery of stored water temperature without direct electrical heating elements. Large 220 L capacity offers extended hot water availability for households or light commercial applications. The vertical design minimises floor footprint while facilitating stratified layering of hot and cold water to improve heat retention. Corrosion‑resistant tank construction enhances longevity and reduces maintenance needs when used with appropriate heat source connections and water treatment.
Suitable for
 Domestic hot water storage for families and multi‑bathroom homes
 Connection to boiler systems for central heating and domestic hot water
 Integration with solar thermal collectors for preheating water
 Small commercial facilities requiring buffer storage for hot water
Key specifications
 Storage capacity: 220 litres
 Heat exchanger type: spiral coil (internal indirect heat exchanger)
 Mounting orientation: vertical
 Intended heating mode: indirect (external heat source required)
 Typical installation location: utility room, plant room or service closet
How to use
Install the water heater according to local regulations and the manufacturer’s installation guidelines, ensuring secure vertical positioning on a suitable floor or base. Connect the spiral coil inlet and outlet to the chosen external heat source (for example boiler or solar loop) using appropriate piping, valves and safety devices. Connect domestic cold water inlet and hot water outlet to the building plumbing, and fit pressure relief and expansion devices as required. Commission the system by filling the tank, purging air from the coil and loops, and bringing the external heat source up to operating temperature while monitoring pressure and temperature indicators.
Usage recommendations
To ensure long service life and efficient operation, use corrosion inhibitors or water treatment where required by local water quality, follow recommended annual inspection and maintenance schedules, and protect the tank and coil from freezing. When integrating with solar thermal systems, include appropriate control and safety components such as temperature sensors, pump station and a controller to optimise heat capture and prevent overheating.
