The Wilson “A5“

The Wilson A5 instantaneous 3-phase water heaters supply a generous 4.5 Litres/minute of hot water, suitable for small households and units, as well as factories and shops.

Formerly Hocking water heaters (A3, A4 & A5)

This water heater has grown in popularity over many decades due to its small compact design (allowing it to fit in the smallest of areas, such as under a kitchen bench or in a linen cupboard). Another reason for its popularity is its strong track record of being reliable and durable (as evidenced by the decades of strong performance under the Hocking Hot Water brand, and continuing this proud tradition under the Wilson Hot Water banner).
