Swimming Pool Heat Pumps: Efficient Heating and Cooling Technology

Issue Time:2022/06/16
Swimming pool heat pumps can quickly become the trump card for today's pool operators. Choosing a pool heat pump is a wise investment and it also helps pool operators comply with current regulations and standards.

Learn all about swimming pool heat pumps in our mini guide and see why this device is now considered a key part of achieving optimal temperature regulation in an efficient way.

1. Swimming pool temperature management: the key to comfort and efficiency

Any pool operator knows the importance of temperature control in aquatic facilities. It is directly responsible for the comfort and providing a flawless pool experience and is also a major source of potential efficiency and energy consumption issues.

Changes in weather (or, more specifically, atmospheric air temperature) can have a significant impact on pool water temperature, thus placing different demands on pool operators who need to heat or cool the water.

Other causes of pool water temperature include evaporation (which also causes pool water levels to drop); use of new water sources for water treatment and replenishment; the presence of swimmers (causing events such as splashes and absorption because of their swimsuits); and rain.

Given these concerns, choosing a temperature management system is a key decision for the following reasons:

Choosing the right temperature management system can bring important energy savings to the operator. This translates into financial savings and additional support for the swimming pool's sustainability claim.

Proper temperature management can also extend the bathing season in the pool, increasing the potential earnings for the operator.

Temperature control is also key to meeting official federation requirements and other standards.

Appropriate systems enable the design and implementation of custom temperature controls, consistent with each pool's needs and primary use.

Water temperature can also affect the performance of a water treatment system, which provides an additional reason to use the right system to monitor swimming pool temperature.

Finally, an adequate heating and cooling system will aid in pool maintenance in the long run.

2. Swimming pool heat pump: what it is and how it works

Swimming pool heat pumps are the most efficient and economical swimming pool temperature management systems available today.

The key to its outstanding energy optimization benefits is the way it works: unlike other conventional pool heating systems, a pool heat pump produces no heat. Instead, it extracts heat from various external sources (the atmosphere is the most common source), amplifies it, and transfers it into the pool water.

Looking further into this process, a swimming pool heat pump works in a closed circuit or cycle, following the following stages:

Warm outdoor air is drawn into the system by a fan.

This air is then circulated through the evaporator coil, where the liquid refrigerant is turned into a gas by heating.

The resulting gas is pumped through a compressor. Due to the compression, the gas temperature value increases to a level of up to 93℃.

Meanwhile, cold water is drawn from the pool and filtered, then pumped into the heat pump using a condenser coil.

The heated compressed gas is contacted with water through a condenser. It then gradually transfers heat to bring the pool water to the desired temperature.

The gas is now cooled to a liquid state again and sent back to the evaporator coil, and the cycle begins again.

3. The benefits of heat pumps

Swimming pool heat pumps are synonymous with optimal water temperature management for the following reasons:

3.1. Energy efficiency

Energy efficiency is measured using the coefficient of performance (COP), which compares the energy consumed to the heat produced. Because it absorbs heat from an external source, a swimming pool heat pump uses minimal energy to generate heat. In fact, it is not uncommon for such equipment to have an above-average COP rating, providing additional heat per unit of energy consumed.

3.2. Cost-effectiveness

Because heat pumps use available external resources to generate heat, they significantly reduce electricity costs. Although the numbers will vary depending on the pool size and climate at the pool location.

3.3. Durability

A swimming pool heat pump is a very durable device because its heating process is aimed at continuous, long-term operation.

3.4. Sustainability

The excellent energy efficiency offered by the swimming pool heat pump gives the device a certificate for being an environmentally friendly solution. There are two reasons why heat pumps represent a greener alternative to traditional gas pool heaters and other similar devices. First, heat pumps can be combined with alternative energy sources other than fossil fuels. Second, they require less energy to heat the pool, which in turn releases fewer greenhouse gases.
