Extremely quiet.

Extremely quiet in operation, the alira LWV impresses with its low noise emission levels. High-quality, noise-optimised processing makes it the ideal choice for all property types and a simple solution for many different requirements. The alira LWV offers the installer the highest degree of planning dependability and flexibility in installation.

Versatile modular solution.

Its unique transport concept allows the alira LWV to be dismantled into its individual parts and transported accordingly. This allows homeowners and installers to enjoy a great deal of flexibility, whether they are building a new system or replacing existing heat pumps. Many options for combination with accessories perfectly adapted to suit the heat pump open up a range of possibilities and guarantee efficient heating, cooling and domestic hot water.

Ideal adjustment.

Perfectly equipped for changing requirements, the alira LWV adapts its output perfectly to current needs: If additional heat is required from the heat pump, it adjusts its operation exactly to this requirement, matching the building’s needs. This results in highly efficient and cost-saving operation.

Efficient with low operating costs

Due to the inverter technology, the LWV heat pumps deliver only as much power as is currently required. This not only protects the heat source, but also makes inverter-driven heat pumps very efficient in operation and guarantees low operating costs.
