Mrs. Hiller

For our wooden house in the middle of the green, of course, only an efficient, environmentally friendly heat pump came into question. With alpha innotec, we have found a reliable partner from the start of planning right through to the start up.

alira LWD
dual air/water heat pump


The highest demands on technology and ecological responsibility make the LWD series, with its timeless and attractive design, the "best-selling model in its class". Innovative details, comprehensive accessories and system solutions also facilitate installation and create the greatest possible flexibility, regardless of whether high output is to be achieved, domestic hot water is to be prepared in addition to heating, or active cooling is required in summer. A further plus point: the LWDV works with the natural refrigerant R290 and is therefore particularly energy-efficient and extremely quiet -  it is future proof and environmentally friendly. In addition, this series is eligible for funding, so it is also easy on the wallet.
