Please Note: This chart is intended as a guide only. It assumes a target water temperature of 28°C for an extended swimming season (Sept–Apr), with an average in-ground pool fitted with a thermal cover, operating for 10 hours per day. Performance may vary depending on factors such as water volume, exposure to wind, shade, soil type, time of year, cover quality, and local weather conditions.
Frequently Asked Questions
Which AquaSolis ASSD heat pump is right for my pool?
The right heat pump size depends on several factors, including your pool volume, location, desired swimming season, target water temperature and whether the pool is covered when not in use.
Choosing the correct size is important for efficient heating and reasonable run times. For more detailed sizing guidance, visit:
Need expert advice? Provide your pool details here and one of our technicians can recommend a suitable heat pump for your pool.
Can the AquaSolis ASSD be used with salt, chlorine or bromine pools?
Yes. The AquaSolis ASSD Series is suitable for pools and spas sanitised with salt, chlorine or bromine.
For reliable performance and long-term equipment protection, pool or spa water should always be correctly balanced and maintained within the recommended chemistry levels. Keeping pH, Total Alkalinity, calcium hardness and sanitiser levels properly managed helps reduce the risk of scale, corrosion and unnecessary stress on the heat exchanger and other pool equipment.
What does COP mean on a pool heat pump?
COP stands for Coefficient of Performance and is a measure of heat pump efficiency. It compares the amount of heat delivered to the amount of electrical energy used. For example, a COP of 10 means the heat pump can deliver around 10 units of heat for every 1 unit of electrical energy consumed under the stated test conditions.
COP varies with factors such as air temperature, water temperature and operating speed, so the efficiency of a heat pump will change as conditions change.
How long will an AquaSolis ASSD take to heat my pool?
Initial heat-up time varies depending on pool volume, heat pump size, starting water temperature, target temperature, ambient conditions and whether a pool cover is used. A larger temperature increase will naturally require longer heating time, while warmer and more humid weather generally allows the heat pump to work more efficiently.
Once the pool reaches the desired temperature, maintaining it usually requires considerably less heating than the initial warm-up. Correct heat pump sizing and the use of a pool cover can make a significant difference to both heating time and running costs.
How many hours per day will the heat pump need to run?
Run time varies with the season and pool conditions. On warm summer days, once the pool is at the desired temperature, the heat pump may only need to run for around 1–2 hours per day. During colder periods, around 8–10 hours per day may be required to maintain the set temperature.
A correctly sized heat pump should generally be able to maintain the required temperature within approximately 16 hours of operation per day under normal conditions, although unusually cold weather may require longer run times. If the heat pump regularly needs to operate for very long periods without reaching the desired temperature, the unit may be undersized for the pool or conditions.
Does colder weather reduce heat pump efficiency?
Yes. Pool heat pumps draw heat from the surrounding air, so less heat is available as the ambient temperature falls. This means heating capacity and efficiency can reduce during colder conditions.
The AquaSolis ASSD Series is designed to operate across a wide ambient temperature range, with automatic defrost helping the heat pump continue operating in colder weather.
What is the difference between single-phase and three-phase heat pumps?
Single-phase and three-phase refer to the electrical supply required to operate the heat pump. Most residential properties use single-phase power, while larger heat pumps may require a three-phase electrical supply.
The required power supply varies by ASSD model, so check the product specifications and confirm the available electrical supply with a licensed electrician before installation.
Where should the AquaSolis ASSD heat pump be installed?
The heat pump should be installed outdoors in a well-ventilated location with sufficient clearance around the unit for unrestricted airflow. It should also remain readily accessible for servicing and maintenance.
Correct positioning is important because restricted airflow can reduce heating performance and efficiency.
Should I use a pool cover with a heat pump?
Yes. A suitable pool cover can significantly reduce heat loss when the pool is not in use, helping the heat pump maintain the desired water temperature more efficiently and reducing unnecessary run time.
