How Does a Pool Heat Pump Work?
Let's set the scene: it's a brisk morning, the birds are chirping, and your pool water is glistening under the early sunlight. And thanks to your pool heat pump, your swimming pool is nicely warmed up and ready when you are.
Pool heat pumps are up to 7x more energy efficient at heating your pool compared to a gas heater because they transfer heat from the surrounding air to your pool water.
How do pool heat pumps work?
Let's break it down in 5 simple steps.
Step 1: The liquid refrigerant, which is colder than the air temperature, absorbs heat from the air.
Even in cooler weather, there is still heat energy in the air.
Step 2: The heated refrigerant becomes a gas and moves to the compressor.
The compressor dramatically and rapidly increases the temperature of the refrigerant gas by- you guessed it- applying pressure (compressing it).
Step 3: The hot refrigerant gas moves to the condenser, which is submerged in the pool water.
The heat quickly warms the circulating pool water.
Step 4: The refrigerant gas cools as it transfers its heat to the pool water.
As it cools, the refrigerant becomes a liquid again.
Step 5: The refrigerant liquid moves to the expansion valve, rapidly cooling even more.
And the refrigerant is primed to absorb lots of ambient heat, restarting the cycle!
