QUESTIONS AND ANSWERS
1) Is it possible that my pool has been losing water since my heat pump was installed?
Your pool is not leaking water, but because of the higher temperature of the pool water, water evaporates more
than before. Indeed, the greater the temperature difference between pool water and air, the more evaporation
occurs.
2) There is water runoff around my heat pump. Could it be leaking?
Your heat pump probably does not have a leak. The water around the heat pump usually results from the
condensation of moisture in the air over the cold evaporator of the heat pump, just like condensation on a glass
of ice water for example. But if you really want to know if a leak is present in your heat pump, you can turn off
the heat pump, but without diverting the water. Wait until the water evaporates around the heat pump. If the
water has not dried within 24 to 48 hours or so, or if there is still more water, then it is very likely that it comes
from a leak. Contact an authorized service center.
3) The temperature displayed on the heat pump is different from that displayed on my pool thermometer. Is
there a problem with my heat pump?
Probably not. Your heat pump includes a controller and calibrated sensors. Most often, the problem lies in the
pool thermometer. Although mercury thermometers are often very precise, their casing is not, and the mercury
thermometer is often offset with respect to the graduations marked on the casing. The thermometer displays
temperatures higher or lower than the actual temperature of the water. To measure the water temperature, you
can use an oral thermometer on which the graduations are more precise.
When pools have a bottom drain, it is also possible that the pool heat pump displays a temperature of 1 to 2
degrees lower than that measured at the surface. This is normal because the water is always colder at the bottom
of the pool than on the surface.
4) Since installing my pool heat pump, the water pressure in the filter pump has increased. Is this normal?
Yes. The new heat pump, as well as new pipes, are creating added resistance to the flow of water in the system.
It is normal to have an increase in pressure of 5 to 7 PSI after installing a pool heat pump.
5) Why doesn’t the pool temperature increase when my pool heat pump is operating?
There are three possibilities, when the heat pump is operating:
-
The heat pump provides more energy than the pool loses: the temperature increases.
-
The heat pump delivers as much energy as the pool loses: the temperature remains stable.
-
The heat pump provides less energy than the pool loses: the temperature drops.
Don’t forget that heat pump performance varies depending on operating conditions. Heat loss from the pool is
dependent on outside temperature, wind and the size of the pool, as well as several other factors.
It is recommended to use an insulating pool cover to reduce heat loss and water evaporation, especially
during cold ni
ghts.
