alira LWA-series - air/water heat pumps for outdoor installation

LW 180A-HT 2

Article Number 100545HT202

The stylish - Economical and powerful heating.

Operating limit flow temperature 20°C to 60°C
Recommended range of application heat source -20°C to 35°C

The heat pumps are recommended for the following total heating demand:
LW 140A = ca. 16kW; LW 180A = ca. 20kW; LW 251A = ca. 27kW; LW 310A = ca. 33kW

For faster installation, the system comes with the following components:

  • The heat pumps are filled with fluorinated greenhouse gas R407C (LW 140A to LW 251A) / R404A (LW 310A)
  • Weatherproof

 

Additionally delivery

  • Electric heating element 9kW (LW 140A to LW 251A) for support during heating operation and domestic hot water preparation
  • Outdoor sensor
  • Electric soft starter (LW 140A and LW 180A)
  • Buffer- and domestic hot water tank (in combination with HT)
  • Impressed current anode and domestic hot water switching valve (in combination with HT)


For LW 310A, the electric heating elements must be selected specificially as necessary accessory. The control and sensor cable must be ordered separately as necessary accessories.
