How does the best heat pump work in 2022?


Pool heat pump is a special device that moves heat from one location to another with a small amount of energy. Pool heat pumps use less electricity because they use heat that is already available. ALSAVO pool heat pumps are used for heating pools to transfer heat from the air into the water.

In the pool water circulates system, pool water passes through pool pump, filter, and pool heater. The pool heater draws in the outside air with fans that direct it over the evaporator coil.

When the ALSAVO pool heater is in hot operation, the low-pressure and low-temperature gaseous refrigerant at the suction port of the compressor becomes high-pressure and high-temperature gaseous refrigerant after being compressed and pressurized by the compressor; the high-temperature and high-pressure gaseous refrigerant is cooled by the titanium exchanger to be high-pressure and high-temperature liquid.

Refrigerant and the water in the titanium exchanger is heated; the high-pressure, high-temperature liquid refrigerant is throttled and reduced by the throttling mechanism (capillary thermal expansion valve, electronic expansion valve), and becomes a low-pressure and low-temperature liquid refrigerant, which is absorbed in the copper tube of the evaporator.

The heat in the air flowing through the copper tube of the evaporator vaporizes into a low-pressure and low-temperature gaseous refrigerant, and the air driven by a fan outside the copper tube is cooled; the low-pressure and low-temperature gaseous refrigerant is sent to the suction port of the compressor. At this point, a heating cycle is completed. In this way, the refrigerant circulates back and forth, continuously transferring the heat in the ambient air and the electric energy consumed by the compressor to the swimming pool water.

ALSAVO pool heaters usually use scroll compressors instead of the standard reciprocal compressors to achieve higher efficiency. The pool heater works efficiently on the outside temperature range -7℃~43℃. The cooler the outside, the less efficient they are and the higher energy bills they result. However, most people use them for outdoor pools during mild weather, this usually isn’t an issue.

Usually, the price of a pool heat pump is more expensive than a gas pool heater. But the annual operating costs of a pool heat pump are typically lower than a gas pool heater because a pool heat pump has higher efficiencies. Pool heat pump last longer than gas pool heaters with proper maintenance. As a result, you’ll save more money in the long run.

When selecting a pool heat pump pool heater, you should consider its:

  • Size
  • Efficiency

There are many factors involving the size of the pool heat pump we chose. Basically, we choose a heater according to the surface area of the pool and the difference between the pool and the average air temperatures. Other factors also affect the heating load for outdoor pools, such as humidity levels, wind exposure, and cool night temperatures. Therefore, we recommend a larger heater.

The energy efficiency of a pool heat pump is measured by the coefficient of performance (COP). The higher the COP number, the more efficient.
