Key information
- Pool series: AQ-Mare Inverno -35
- Published range: 3 to 35 kW models at pool conditions
- Heat exchanger: Titanium pool-water circuit
Cold-climate inverter pool heat pumps for extended-season operation.
Pool heating demand depends mainly on surface area, wind, air temperature, water temperature and operating hours. AQ-Mare Inverno -35 is designed for pool heating and cooling at low outdoor temperatures.
Calculate heat loss, not volume alone
Evaporation from the pool surface is often the dominant loss. A cover, wind protection and usage schedule can change the required duty substantially.
- Open surface and target water temperature
- Local wind and humidity
- Cover use during closed hours
Check the winter duty point
Output quoted in warm air does not describe shoulder-season or sub-zero operation. Compare capacity and COP at the expected outdoor temperature and allow for defrost.
- Low-ambient capacity
- Available recovery time
- Pool-side flow and pressure drop
Sizing inputs
| Input | Impact |
|---|---|
| Pool surface area | Drives much of the evaporation loss. |
| Air temperature and wind | Increase or reduce surface heat loss. |
| Pool cover | Can reduce the maintenance load substantially when used consistently. |
| Operating hours | Set the output needed for maintenance and recovery. |
Mistakes to avoid
- Sizing from water volume alone.
- Using output declared only at warm-air conditions.
- Ignoring the cover, wind and recovery period.
Frequently asked questions
Does a pool cover reduce required output?
Yes. Reducing evaporation and night losses can lower the maintenance load significantly.
Can the unit cool the pool?
AQ-Mare Inverno models support heating and cooling; confirm the operating range of the selected model.
