If you know in advance that you want an appliance that provides both heating and cooling, then the BWL-1S split air source heat pump is the one for you. In highly insulated houses there may come a point during the summer when your home starts to store heat. This is when this additional, space saving and efficient cooling option might be very welcome.
The BWL-1S variably adapts its performance to your demand: this applies to heating, cooling and DHW operation. The outdoor unit takes up little space and can either be mounted on a floor or wall mounting bracket. And if you live in a region where it gets very cold in winter or at night, then an additional electric booster heater will reliably provide you with cosy warmth.
