alira LWD-series – dual air/water heat pumps for outdoor installation
Article Number 100606HMD02
The bestseller - future ready with natural refrigerant.
Operating limit flow temperature 20°C to 70°C
Recommended range of application heat source -22°C to 35°C
The heat pumps are recommended for the following total heating demand:
LWD 50A = ca. 7kW; LWD 70A = ca. 9kW; LWD 90A = ca. 11kW
For faster installation, the system comes with the following components:
- Heat pump controller Luxtronik 2.0
- Electric heating element for support during heating operation and domestic hot water preparation
- Energy efficient circulation pump
- Expansion vessel (don´t fit with HMD 2)
- Heat quantity recording
- Safety assembly
- Shut-off valve (fill and drain valve)
- Overflow valve (in combination with HTD)
- Switching valve for domestic hot water (in combination with HTD)
- Optionally suitable for cooling up to +7°C flow temperature. Cooling is deactivated and can be activated by the installer during the commissioning (only RX-series).
- Filled with natural refrigerant R290
- Outdoor sensor
- 8 m LIN Bus cable
- 8 m control cable
- 8 m load cable
