Introduction
Overview
Your Pentair heat pump will provide you with years of heated pool enjoyment. Heat pumps operate by taking heat
from the surrounding air and transfering it into the water. The warmer the air and the more humid the air, the more
latent heat is available for heating your pool. With a properly sized heat pump for your pool, the heat pump should
raise your pool on average 1° F. per hour depending on air temperature, humidity, and water temperature. The
ideal or rated condition for the heat pump is 80° F. air temperature, 80% relative humidity, and 80° F. water
temperature. As conditions decrease from 80/80/80, the heat pump performance will decrease slightly.
Heat Pumps are best utilized to maintain a set water temperature; they are not intended to provide instant or fast
heating. It is not reasonable to expect a heat pump to perform like a gas heater which has a much higher BTU
output and faster response. Additionally, gas heaters are not dependent on environmental conditions. Swimming
pool heat pumps are very similar to home heating and air conditioning heat pumps and therefore should be treated
similarly.
Proper operation and use of the heat pump is to set it at your desired temperature and leave it. Your heat pump
will turn on and off automatically to maintain your desired temperature much like your home HVAC unit. To take
advantage of the suns energy operate your heat pump during the heat of the day. Your heat pump will still operate
when the temperature dips at night, but the output will be decreased.
It is acceptable to shut the heat pump off and not use it for extended periods of time. When you have a need to
heat your pool, please plan accordingly because it may take the heat pump days to heat your pool back up to your
desired temperature depending on your pool temperature and environmental conditions.
