A Guide to Choosing the Right Swimming Pool Heat Pump


Swimming pool heat pumps provide an energy-efficient way for pool users to maintain consistently warm water in their pools and spas all year round. Rather than generating heat like gas or electric heaters, pool heat pumps capture energy from the outside air which it then transfers into the pool water in order to heat it. Once activated, the heat pump’s fan pulls warm air into its evaporator coil, where it warms the liquid refrigerant, converting it into a gas. This gas is then compressed, increasing its temperature further. After reaching the desired temperature, it flows into the heat exchanger, where it heats the pool water. Afterward, the heated water circulates back into the pool while the gas reverts to a liquid state, ready to begin the cycle anew. When you choose Aqauaheat pool heating, you also get the added benefit of InverPad Technology, which is not only one of the quietest heating systems available, but is also one of the most energy-efficient. In fact, it can cut down your energy usage by an average of 90%.

Swimming pool heat pumps provide an efficient and cost-effective solution for heating your pool. They serve as an excellent alternative to gas heaters and are ideal for maintaining warm pool temperatures throughout the year.

What’s the Difference Between a Gas Pool Heating and an Air Source Heat Pump?

In short, gas pool heaters burn fuel to directly create heat, whereas air source heat pumps extract heat from the surrounding air to warm the pool, making them generally more energy-efficient. Gas pool heaters can use natural gas or LPG as their fuel; the gas combusts in the heater’s combustion chamber, producing heat that is transferred to the water before it cycles back into the pool. Conversely, an electric heat pump does not use a heating element but instead harnesses heat from the external air. Approximately 70-90% of the energy required to operate the heat pump is derived from the air, with the remainder provided by electricity. Using air as its primary energy source lowers your heating costs considerably, making an air source heat pump a cheaper more environmentally friendly alternative to pool heating.

Why Use a Heat Pump for a Pool Water Heating?

Heat pumps allow you to set your pool at your ideal temperature, and then keep it that way, as they are excellent at keeping a consistent temperature. Heat pumpsrequire very little effort to operate. They are designed to be user-friendly, offering simple controls and automated features that make managing your pool’s temperature effortless. Their straightforward installation and operation allow for easy integration into existing pool systems. In addition to this, heat pumps provide:

  • Energy Efficiency: If you’re hoping to keep your energy costs as low, you will find that heat pumps offer excellent value. Heat pumps are more energy efficient than gas heaters because they transfer existing heat from the air rather than burning fuel to generate new heat. While a gas heater can heat your pool more quickly, that speed comes at a higher energy cost. In contrast, a heat pump can provide you with steady and consistent heating after it reaches your desired temperature, and can do so far more efficiently than a gas heater.
  • Durability: Heat pumps are designed to last. They’re built with sturdy components that have been engineered to operate in varying weather conditions, and they typically require very little maintenance. Their long operational life spans ensure reliable performance year after year.
  • Easy Maintenance: Heat pumps require less maintenance than other heating systems due to their fewer moving parts and the absence of combustion-related components. Regular checks and basic cleaning are typically all that’s needed to keep them running efficiently.

The Right Heat Pump for Your Pool

When selecting a heat pump for your swimming pool, it’s advised that you consider the following factors before you buy:

  • The Volume of the Water: The size of your pool significantly impacts a heat pump’s heating capacity requirements, so it’s critical that you consider this before you buy, as the heat pump’s capacity will need to correspond to the pool’s volume. To determine this, you first need to calculate the volume of your pool in cubic metres (m³) using the following formula: length x width x depth (water level). As it takes 1kW of heat to warm 4m³ of water, the minimum heating capacity required for your heat pump can be calculated by dividing your pool’s volume in m³ by 4.

  • Climate & Environmental Factors: Factors such as humidity, wind chill, and temperature fluctuations will also play a role. For instance, opting for a larger pool heat pump is advisable if you live in an area that’s got a drier climate, higher wind speeds, or low nighttime temperatures.

  • Heat Pump Size & Capacity: Make sure the heating capacity of the heat pump is appropriate for your pool’s size. A heat pump that is too small will not heat the water effectively, whereas one that is too large can consume unnecessary energy.

  • Noise Levels: For the sake of your neighbours as well as your own serenity, it’s highly recommended that you don’t get a heat pump that’s too noisy. As with certain other machines, heat pump noise levels are measured in decibels (dB). The sound of leaves rustling is around 20dB, whereas a lawnmower sits around 90dB. A good, quiet heat pump should sit somewhere between 30dB to 40dB, which is somewhere between a gentle whisper to the sound of a quiet library (an Aqauaheat pump clocks in at 36.8dB).

  • Degree of Use: The frequency and intensity of pool use significantly influence the type of heat pump you should consider. If you fancy a regular dip in the pool, especially in the colder months, then it’s recommended that you invest in a heat pump with a higher capacity and more robust features to maintain a consistent water temperature efficiently. On the other hand, for pools that are used less frequently or chiefly in the warmer seasons, then a smaller, less powerful heat pump might suffice, as the demand for heating is lower and less constant. Assessing how often and in what conditions your pool will be used can help you choose a heat pump that balances performance with energy efficiency, ensuring optimal functionality without excessive power consumption.
