Desuperheating for DHW

I see a product from Olive Tree Energy called a ZeroEnergy Water Heating System. Any experience with these or similar products. Is it a good concept? Maybe one of these added to an indirect tank and electric backup so you can turn the boiler off for the summer.

    The concept is great. It is proven and largely underutilized technology.
    I am not sure I am sold on Olive Tree's insistence that a thermosyphon is better that pumps and controls.

    Worked well as DHW preheater before code requiring double wall. When that requirement came in desuperheater-heater became more expensive and produced lower temperature.

    Presumably code requirement won't apply to CO2 refrigerant?
