Description
W'eau Vertical Full Inverter pool heat pump - 21 kW
The W'eau Vertical Full Inverter 21 kW is the heat pump for those who want to combine maximum power with flexibility in a compact garden. Thanks to its vertical air outlet, you can place this heat pump where a traditional heat pump simply won't fit. It heats pools of up to 120,000 liters (recommended up to 63,000 liters for maximum inverter efficiency) and delivers exceptional performance thanks to a Mitsubishi compressor, twisted titanium heat exchanger and a high quality ABS exterior. Quiet, economical, reliable and smart: exactly what you are looking for when you want to enjoy carefree warm pool water.
High performance heat pump with vertical discharge
The vertical air discharge is the biggest advantage of this W'eau heat pump. Because cold air is blown upward, you don't have to leave a long free zone at the front as with horizontal models. Thus, this heat pump fits perfectly in smaller gardens, next to a wall or between vegetation - without cold air blowing toward your patio.
The sturdy ABS casing makes the heat pump completely stainless, even in humid conditions. The Mitsubishi inverter compressor is known for its high reliability and quiet operation. In combination with the twisted titanium heat exchanger, the heat pump delivers an exceptionally high COP efficiency as high as 1 in 15.8. In the process, noise levels remain low: a maximum of 36 dB at 10 meters, and thanks to inverter control, often even lower.
Smart heating with Full Inverter technology
The Full Inverter technology ensures that the heat pump always uses exactly the right power. It automatically switches on when the water needs to heat up quickly and runs very low when the temperature just needs to be maintained. You notice this immediately by:
- Much lower energy consumption, even with long use
- Constant water temperature without fluctuations
- Quiet operation as the pump rarely runs at 100%
An ideal combination for those who want economical and comfortable heating from April to October.
Integrated wifi module and four smart programs
With the built-in wifi module, you control everything via your smartphone. Whether you choose the program, adjust the water temperature or want to receive notifications - you control everything from your lounger. The heat pump features four programs:
- Auto - automatically switches between heating and cooling based on water temperature.
- Eco - energy efficient mode for daily heating; does not switch to cooling.
- Boost - maximum power to bring the pool to temperature in a short time, ideal in pre-season.
- Cooling - allows the heat pump to actively cool during extremely hot days.
Prefer manual operation? That can also be done easily via the display on the pump.
Efficiency and consumption W'eau Vertical Full Inverter 21 kW
Below is the overview of heat output (COP) per outside temperature:
| Outdoor temperature | COP range | Heat output per 1 kW of energy |
|---|---|---|
| 15°C | 4,9 – 7,6 | 4.9 to 7.6 kW heat |
| 26°C | 6,8 – 15,8 | 6.8 to 15.8 kW heat |
At summer temperatures (26°C), the heat pump operates extremely economically - ideal for the peak season. Even at lower temperatures (April, September, October), this model is among the best performing inverter heat pumps.
Easy installation thanks to compact design
Due to the vertical emission, this heat pump does not need any free space at the front. You only need to take into account:
- 80 cm free space at the rear (air intake)
- Connection via bypass kit (not included as standard).
- Installation before automatic disinfection in your pipework
The bypass allows you to fine tune the flow to the heat pump, further improving efficiency.
