Swimming Pool Heat Pump
A Heat Pump uses electricity to
operate. They are actually a form of
solar heater, as the sun-warmed air
contributes to the efficiency of these
units.
This heat is extracted from the air,
upgraded with a compressor, and
then transferred to the water.

For those who enjoy swimming regardless of the weather, a Heat Pump is the
recommended method. It is also the preferred method for therapy or athletic trainers, and
also when a home is not "solar feasible" (i.e. solar will not fit on roof.) A heat Pump, when
properly sized, can maintain any desired pool temperature between 80 and 90 degrees,
regardless of outside weather conditions. A Heat Pump will work when the outside air
temperature is above 45 degrees.
Due to their high efficiency, heat pumps have a low cost of operation. Typically, for every 20
cents of electric input, you receive $1.00 worth of heat.
Types of Heat Pump Pool Heaters
There are two basic types of swimming pool heat pumps. The most common is an
"Air-Source", the other being "Water-Source". Air Source Heat Pumps use air as a heat
source. Water Source Heat Pumps get their heat source from water i.e. lake, river, or well
water. Water source units are generally used for special applications.
Longevity and Maintenance
Heat pumps will typically last between 10 to 15 years or more. Because heat pumps are a
mechanical device with many moving parts, they require periodic service by an A/C
technician. Heat pump factory warranties vary from 5 - 15 years.
