Air source heat pump

The BWL-1-A for outdoor installation enables you to draw thermal energy for your home directly from the ambient air.

Tap into an energy source with almost unlimited availability – air. The BWL-1-A heat pump transforms this freely available natural energy and reliably supplies your home with heat and domestic hot water. For this, the externally installed appliance operates highly efficiently, with 3.8 times more thermal energy for central heating and domestic hot water being generated than the electrical energy required for operating the heat pump. A further benefit is that the BWL-1-A operates very quietly and, in addition, features a selectable night mode, for even lower noise levels during appliance operation. This means you can rest assured that neither you nor your neighbours will be disturbed.

Quiet and Powerful

The ultra-quiet BWL-1-A air source heat pump for outdoor installation generates pleasant warmth from the energy latent in the ambient air.

Sometimes everyday life is noisy enough. Thankfully, the BWL-1-A operates very quietly and also features a selectable night mode, for even lower noise levels. So while you relax in your garden or on your patio, the unit's muted operation will disturb neither you nor your neighbours.

Whether for new build or renovation, a heat pump is a sound alternative to gas and oil, as the BWL-1-A taps into the free energy latent in the outdoor air to generate heat. If you already have your own PV system, you can even operate this heat pump with power generated on site. Now that sounds like good news for the environment.
