Aquafficient is an innovative, modern and highly efficient solution to heating water.

Patented Space Saving Electric Hot Water System

Aquafficient stores heat in a unique phase change material, known as a heat battery. Once the battery has been fully charged, it will pass the heat energy that has been stored inside to the cold water coming into the unit.

The cold water comes into a highly efficient heat exchanger that has been embedded within the battery, and this transfer of heat only happens when hot water is called for. This electric instant water heater or boiler, provides hot water until the battery is depleted. The battery will recharge itself to ensure you have access to hot water 24/7.
