Hot Water on Demand With No Water Storage

About Aquafficient

Aquafficient is an innovative, modern and highly efficient solution to heating water. This instant electric water heater from Fischer uses a single heating element and patented thermal storage technology, to provide instant hot water without the need for tanks. Instead, the hot water is produced from stored heat energy within a unique phase change material.

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 instant electric water heater provides hot water until the battery is depleted. The battery will recharge itself to ensure you have access to hot water 24/7.
