Pool heat pumps pull warmth from the ambient air and pass it to the pool water. Unlike conventional pool heaters, an inverter pool heat pump requires only minimal electricity to run the fan and compressor.
Choosing a pool heat pump offers many benefits, including exceptional energy efficiency and the ability to heat your pool regardless of sunlight. Selecting a pool heat pump that matches your specific conditions is vital to achieving optimal and cost-effective performance, maintaining a comfortable pool temperature, and keeping energy expenses low.
Vital questions you need to ask when considering your pool heating options:
- How long do you want to swim? Are you looking to extend your swimming season by a few extra months, swim whenever you like or enjoy your pool all year round?
- What temperature do you prefer for swimming? Do you want the water to be 25, 28, 30, or warmer than 30 degrees?
- Do you have a pool cover? If not, know that a pool cover is crucial for heating your pool efficiently.
Factors That Impact the Size of a Heat Pump:
- Pool Size (surface area in square meters): Larger pools need more powerful heat pumps.
- Desired Swimming Season Length: Extending the swimming season, such as swimming year-round, necessitates a heat pump with a larger capacity.
- Local Climate: Colder climates demand heat pumps with higher output.
- Pool Cover Usage: Using a pool cover minimises heat loss, allowing for smaller heat pump sizes.
- Power Supply (solar PV, 3-phase, etc.): Installation may require assistance from an electrician.
Calculating Your Pool’s Surface Area
- Measure the length and width of your swimming pool in meters.
- Multiply these measurements to find the surface area in square meters (m²).
- Use our sizing charts to determine the appropriate heat pump size based on your pool’s surface area in m².
How Climate Determines the Required Heat Pump Output?
- Warmer Climate: Requires lower kW output.
- Colder Climate: Requires higher kW output.
How to Determine the Correct Size for Your Pool Heat Pump?
If you want to evaluate the right size for your pool heat pump, divide your pool’s volume by 2500 to find the required kW. For instance, if a pool measures 4 x 6 meters with an average depth of 1.5 meters, it will have a volume of 36,000 litres. So, divide 36,000 litres by 2500, which will give you 10.4. That means your pool heat pump should have a minimum output of 10.4 kW. (For this calculation, we assume the use of pool cover).
Selecting a Heat Pump Model
Use our quick selection charts tailored to your pool size and climate, and consider the location of your pool equipment. A top discharge model might be required for tight spaces, while areas with more space can choose horizontal discharge models like the ultra-inverter. Selecting the most efficient model that fits your requirements will help minimise ongoing energy costs.
The Significance of Using a Pool Cover
- A pool cover is indispensable for pool owners. A pool cover helps reduce water evaporation and maintain water temperature, allowing you to use a smaller pump.
- The sunny weather in Australia can lead to significant water loss—up to 55,000 litres annually—through water evaporation in an uncovered domestic pool. This loss includes expensive pool chemicals and salts, expenses that can be avoided.
- Selecting a well-fitted solar pool cover can prevent up to 97% of water evaporation, saving hundreds of dollars on pool care products depending on your pool’s size.
