HOW A HEAT PUMP WORKS

HE FOLLOWING EXPLANATION IS PROVIDED TO HELP YOU IN
UNDERSTANDING WHAT TO EXPECT FROM YOUR HEAT PUMP
…
A Heat Pump Does Not Make Heat…
Heat pumps are so extraordinarily efficient because they do not need to produce
heat in order to warm pool or spa water. Rather, heat pumps simply transfer heat
from the outside air into the pool or spa water. If one considers that absolute
“0”–the point where all heat is absent–occurs at 459º Fahrenheit below zero, it
becomes evident that outside air–even at the relative cool temperature of
55ºFahrenheit–still contains large amounts of heat energy. It is that abundant heat
energy that a heat pump captures and places into your pool or spa.
