The 270L iStore uses exclusive technology to provide 482% efficiency

Here's how it works

A fan draws in air, containing heat energy, across the evaporator
The evaporator turns the liquid refrigerant into a gas
The compressor pressurises the refrigerant into a hot gas
The hot gas inside the condenser coil heats the water inside the coil-wrapped tank
The refrigerant reverts back to a liquid after heating the water and continues to the evaporator for the process to start again
The cycle continues until the set target temperature is achieved
