1. What Heat Pump is?
What It Composes
A water heater is basically composed of a compressor, an evaporator, some capillary or expanding
valves and a condenser.
How it works
Heat pumps use electricity to capture heat and move it from one place to another. They don't
generate heat. As the pool pump circulates the swimming pool's water, the water drawn from the pool
passes through a filter and the heat pump heater. The heat pump heater has a fan that draws in the
outside air and directs it over the evaporator coil. Liquid refrigerant within the evaporator coil absorbs
the heat from the outside air and becomes a gas. The warm gas in the coil then passes through the
compressor. The compressor increases the heat, creating a very hot gas that then passes through
the condenser. The condenser transfers the heat from the hot gas to the cooler pool water circulating
through the heater. The heated water then returns to the pool. The hot gas, as it flows through the
condenser coil, returns to liquid form and back to the evaporator, where the whole process begins
again.
