With the unique design of the ECH2O thermal store, there is no risk of bacteria or need to disinfect the tank.

Increase energy efficiency and savings

Our ECH2O domestic hot water heat pump is the ideal combination of Daikin’s signature heat pump technology and a high performance water storage tank to achieve 3 times less electricity than traditional water heaters. Users can also connect their solar energy to achieve the highest levels of energy efficiency and substantial savings.

Maximum efficiency

The hot water storage tank is designed to maximise the efficiency of hot water production:

  • Multiple layers of polyurethane foam fully insulate the water heater
  • Stainless steel heat exchanger, with a capacity of 29 litres, runs the entire length of the tank.
  • Provides hot water at all levels.

Energy savings

By combining a heat pump and a hot water storage tank, you achieve optimal savings:

  • Reduce the electricity required to produce domestic hot water by up to 70%, (compared to a traditional hot water heater).
  • Nearly instantaneous production of hot water, without additional electric power for the water disinfection cycle.

Hot water savings with solar energy

Reduce your energy costs by taking advantage of the sun's renewable energy. Our solar panels are easy to install and produce up to 70% of the energy your hot water heat pump needs. Equally available for all building types, our solar hot water systems accommodate small and large homes. Choose between a pressureless or pressurised hot water system.
