How long should it take to heat a pool with a heat pump? ›

On average, this could take from 12-48 hours, but there are a series of factors that influence the time period it takes for a pool to heat up completely.

This morning it is much cooler and the heat pump is showing LP on the display. Why? Hayward heat pumps will cut off on low refrigerant pressure (LP) when the outside temperature drops to approximately 45° Fahrenheit. The heat pump will restart automatically when the heat pump warms back to approximately 65°.

The model is inside the pool heater. I do not need the Aqualink model number. Anyways the answer is as I mentioned before. (open water temp sensor) That means the control board can no longer read the temperature of the incoming water.

Any heater installed with restrictive devices in the piping system downstream from the heater, (including check valves, isolation valves, flow nozzles, or therapeutic pool valving), must have a relief valve installed as described above. When installing this kit, basic safety precautions should always be followed.

The flame rollout switch is a safety feature that shuts off the gas supply to the burner if the flame blows out. This can happen for several reasons, such as a dirty burner or a blocked flue. A flame rollout can also be caused by a faulty gas valve or a problem with the electrical igniter.

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.

Generally speaking, the lifespan of an air source swimming pool heat pump can be as long as ten years. If you use your pool heat pump properly, keep it well maintained, and ensure your pool's water chemistry is balanced, your pool heat pump can last longer than expected - up to a decade or more.

We only recommend leaving a pool heater overnight to commercial pool owners who expect customers 24/7. That's because it takes three to four hours to heat a sizeable swimming pool. It takes even longer at night when the water has been sitting still for several hours.

There are different models of Hayward units, some use a spark igniter, some use a glow igniter. Most of the time, the IF code means that the igniter has failed, the gas valve has failed, or on units with flame sensing technology, the flame sensor is dirty and needs to be cleaned with sandpaper.

PO or OP is an indication of an open water temperature sensor. Summit style heat pumps use a 4.8k ohm sensor, and HeatPro heat pumps use a 10k ohm sensor. The most common cause of PO or OP error code is an open water temperature sensor.

What is the life expectancy of a Hayward pool heater? ›

7-10 years is the average life expectancy of a pool heater.

Your heater may have inadequate water flow due to a dirty filter, closed valve, external bypass, reversed water connections, or pressure switch out of adjustment. It is also possible that your thermostat is out of calibration or needs to be replaced.

A dirty pool filter wins for the most popular water flow issue on a heater service call. Luckily, it's also the easiest one to diagnose and fix. You can overcome this issue by having a pool heater service tech or pool specialist remove the filter and run the pump again without a filter in.

In order to tell if the valve is open or closed, the general rule is, if the handle is switched 90deg to the flow, it is off. As you can see from the diagram above, if the handle is in line with the flow path, it is on. Simple.

Water circulates through the heater core all the time the pump is running, whether the heater is on or off. If the heater springs a leak, you have to shutdown the pump, which stop waters circulation, filtering and chlorinating your pool.
