How H2o Works

Super Efficient Heating, Hot Water and Ventilation System

  • The EcoVolt H2o uses a powerful fan to pull air from bathrooms, kitchens and the atmosphere. This air flows across an evaporator containing a low temperature, low pressure refrigerant.
  • The heat in the air is transferred to the refrigerant via the evaporator, then released into the atmosphere. The air leaving the system is now cold, due to the heat being drawn from it into the refrigerant.
  • The refrigerant having extracted the heat from the air, then moves to the panasonic compressor, which increases the refrigerants pressure & temperature.
  • This high pressure, high temperature refrigerant travels from the compressor to the condenser coil inside the tank. The heat from the refrigerant transfers to the water via the coil.
  • Having transferred the heat to the water, the refrigerant returns to a low temperature and pressure, and reverts to the evaporator.
  • The cycle continues until the refrigerant has transferred enough heat to bring the stored water to its desired temperature.
  • Once the water has reached the desired temperature, the EcoVolt H2o will switch off.

Uses 70% Less Energy

Using 70% less energy than traditional electric water heaters on the market, The EcoVolt H2o takes waste heat from the surrounding internal air to heat your domestic hot water. The system comes in 3 sizes ( 190L, 260L,300L), suiting small apartments to large family homes.

Up to 70%



H2o System Specifications

  • Efficiency (COP) of 4.1 measured to European standard EN 16147
  • Efficiency COP 2.86 with internal air supply of 7°C. Efficiency COP increases to 4.1 with an internal air supply of 20°C
  • Heating capacity of 2800W with electric consumption of 700W
  • The 260 L and 300 L models come with an additional hybrid coil that can be connected to a thermal solar panel or boiler if required
  • Internal tank insulation means the temperature only drops 1°c every 6 hours
