Key information
- Series: AQ-Acqua Uno R290
- Available storage: 200, 250 and 300 litres
- Refrigerant: R290
R290 heat pump water heaters in 200, 250 and 300 litre sizes.
Select storage volume from the hot-water usage profile, not headcount alone. AQ-Acqua Uno R290 combines a heat pump and storage cylinder in a compact year-round DHW unit.
Size from the draw-off profile
Simultaneous showers, baths, peak periods and storage temperature determine useful volume. A larger cylinder provides more reserve but needs more space and energy to recover.
- Number and duration of showers
- Simultaneous draw-off
- Installation space and access
Check the air path and plant room
The unit draws heat from air. Confirm room volume, ducting, inlet-air temperature, condensate drainage and the effect on room temperature.
- Inlet and exhaust air route
- Condensate drain
- Sound and operating schedule
Initial comparison
| Storage | Usage profile to check |
|---|---|
| 200 L | Apartments and households with distributed draw-off. |
| 250 L | Family use with more reserve and moderate peaks. |
| 300 L | Higher draw-off, hospitality or longer autonomy. |
Mistakes to avoid
- Choosing storage from headcount alone.
- Ignoring cooling of the plant room.
- Omitting condensate drainage and service clearance.
Frequently asked questions
Does the electric heater replace the heat pump?
No. It supports rapid recovery or specific operating cycles; normal efficient operation remains with the heat pump.
Should I choose 200 or 300 litres?
Use peak draw-off, storage temperature and available recovery time to decide.
