Heat Pump Pool Heaters

Zodiac HPT3216

Frequently Asked Questions

Is it possible that my pool is losing water since my pool heater was installed?

Your pool is not losing water, but because the pool water is at a higher temperature, there is more evaporation. When
the difference of temperature between the pool water and the surrounding air is increased, more evaporation happens.

Some water drips beside my pool heater, does my pool heater have a leak?

It probably does not. The water dripping from your pool heater comes from condensation or the humidity on the evaporator of your pool heater, just as condensation forms on a cold water glass for example. But, if you really think a leak could be present in your pool heater and want to be sure, you can turn off the filter pump and the pool heater, or turn off the pool heater and use the by-pass valves to prevent water from circulating through your pool heater. Wait until the water evaporates beside the pool heater and open the valves to have the water circulate again into the pool heater without putting the pool heater on. If water drips, it comes from a leak, not from condensation.

My pool heat pump indicates a temperature that is different from the temperature indicated on my pool thermometer. Does my pool heat pump have a problem?

Chances are that it does not. Your pool heat pump features a calibrated digital control and sensors. Most of the time, the problem comes from the pool thermometer. Even though the mercury thermometer is precise, its box is not and the thermometer may not be in line with the graduations written on the box. In this condition, the thermometer reads a temperature higher or lower than the real pool temperature. When the pool features a bottom drain, it is possible that the pool heater shows a temperature a few degrees lower than what is measured on surface. This situation is normal since the water at the bottom of a pool is always cooler than on surface.

Since the installation of my pool heat pump, the pressure in my filter pump has risen, is it normal?

Yes. The new heat pump, as well as the new tubing, is an added resistance to the water flow. Therefore, it is normal to have a rise in pressure of 5 to 7 psi after the installation of a new pool heat pump.

Why isn’t the pool water heating as my pool heat pump is working?

We should not forget that the pool heat pump efficiency varies with the operation conditions and that the energy losses of the pool are relative to the outdoor temperature, wind, size of pool and many other factors.

  • Temperatures below 43° F will limit the ability of a heat pump.
  • The heat pump may need to run longer to reach the desired temperature.
  • Strong winds over the pool surface will prolong pool heating.
  • The use of a solar blanket or cover will help improve the heat pump’s efficiency and reduce warm water evaporation.

What do I do if there is an error code on the display?

In the event you receive an error code on your heat pump display screen, please reset the breaker for the heat pump. Wait 5 minutes for the unit to reset. If you are still receiving an error code, please call ZODIAC customer support center at 1-800-830-4808.
