The heat pump animation shows how a heat pump works to heat water for a geyser. Outdoor air passes through an air to gas heat exchanger, raising the temperature of refrigerant gas. A compressor then increases the gas temperature to 55 degrees Celsius. This heat is transferred to water circulated from a geyser via a gas to water heat exchanger. As heat transfers, the refrigerant cools and an expansion valve further lowers the pressure and temperature before it passes back through the air to gas heat exchanger.

3. HEAT PUMP ANIMATION
The Refrigerant heat is transferred to the water that has been circulated from the
geyser, heating the geyser water up to around 55 degrees Celcius.
