The
Hayward HeatPro takes the heat from the surrounding
air and uses it to heat the water in your pool.
During heat pump
operation, liquid freon from inside the unit is
pumped through the system (A) and is turned into
a heated gas. This happens when heat is taken from
the surrounding air (B) as it is drawn through the
evaporator by the fan. The compressor (C) receives
this warmer gas and compresses it to a higher pressure,
resulting in the freon reaching even higher temperatures.
As the unit sends the heated gas through the heat
exchanger, the gas gives up its heat to the surrounding
water (D). The freon is then reverted to its liquid
state which completes the cycle (A).
The water (F), which
is being forced through the heat exchanger (D) by
your pool pump, is heated by three to five degrees
as it passes through the heat exchanger. The water,
now warmer, then flows back into your pool (G).
