    How does the iStore heat pump (R290 refrigerant) work?

    The 180L iStore utilises proprietary technology to achieve 400% efficiency. Here’s the mechanism behind its operation step by step:

    Air containing heat energy is drawn in by a fan across the evaporator.

    1. The evaporator transforms the liquid refrigerant into a gas.
    2. The compressor increases the pressure of the refrigerant, turning it into a hot gas.
    3. The heated gas within the condenser coil warms the water inside the tank, which is wrapped around the coil.
    4. After heating the water, the refrigerant returns to its liquid state and cycles back to the evaporator to repeat the process.
