Heat Exchange Geyser

A heat exchanger geyser uses ambient heat (from air or solar) to heat water, acting like a "heat magnifier" for significant energy savings, often 60-70% less electricity than traditional elements. It works by transferring heat from a source (like outside air via a heat pump or sun via panels) to water in a tank, using a refrigerant cycle or direct circulation, often integrating with or replacing standard electric geysers for efficiency.
