Heat pump water heaters operate differently than conventional water heaters. Rather than generating heat directly, they extract heat from surrounding air and transfer it to water stored in the tank. This thermodynamic process consumes significantly less electricity than traditional resistance heating methods.
These units consist of an evaporator that absorbs ambient heat, a compressor that increases the temperature of the refrigerant, a condenser coil that transfers heat to the water, and an expansion valve that completes the refrigeration cycle. This technology enables heat pump water heaters to achieve efficiency ratings of 3.0-4.5 UEF (Uniform Energy Factor), compared to 0.9-0.95 for standard electric models.
Heat pump water heaters come in two main configurations: integrated units with the heat pump mounted atop the storage tank, and split systems where the heat pump is separate from the tank. Integrated units are more common in residential applications and typically easier to install, while split systems offer more flexibility for complex installations.
