Split air source heat pump

The heat pump that delivers heating and cooling too.

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.

Split air source heat pump BWL-1S

The perfect heat pump for heating and cooling with an additional electric booster heater for higher heating output, particularly at low temperatures

The BWL-1S is the energy efficient solution for heating, cooling and DHW operation that variably adapts to your demand. The outdoor unit takes up little space and can either be mounted on a floor or wall mounting bracket.

  • High efficiency, with a COP of up to 3.8 (EN 14 511), means little electricity is required to operate the heat pump
  • Equipped with an electric booster heater (6 kW) for providing additional heat when outside temperatures are low
  • Save energy with efficiency class A++
  • Easily monitor your consumption with the integral heat meter
  • All WOLF products communicate with each other via the WOLF control unit. This means they are also very easy and intuitive to operate as a system overall
  • Operation with integral BM-2 programming unit or AM display module
  • Can be combined with other heat generators (oil/gas/biomass/solar)
  • Optionally also available as a heating centre, meaning in combination with the CEW-2-200 DHW cylinder
  • Its LAN/WLAN interface module enables the BWL-1S to be SmartHome compatible and so easily operated via the WOLF SmartSet app or web browser

If you prefer an indoor environment that remains as near constant as possible, then you can rely on the BWL-1S.

By choosing a heat pump you save money and reduce CO2 emissions. Heat pumps are particularly suitable for new build and renovated, well insulated buildings, as these provide the right conditions for achieving a good or very good ratio of energy input (electricity) to heat output. The required power is mostly supplied at favourable special tariffs by local utilities – or by your own photovoltaic system.

Innovative heat pumps from WOLF can easily be linked to other appliances to create an indoor environment to suit your and your home. Our heat pumps can, for example, be combined with a WOLF heat generator of your choice (oil, gas or solar) and one of our DHW cylinders. What's more, with WOLF programming units and our Smartset app you can control all of your appliances easily and intuitively, regardless of whether you are at home, in the office or on holiday. This means you always have a relaxing bath or cosy warm living room waiting for you – while also protecting the environment.

Whether you're looking at heating, ventilation or cooling

Whether you're looking at heating, ventilation or cooling – at WOLF we are only satisfied when all these elements come together to provide you with an indoor environment where you can truly relax. We want technology to fit around you, not the other way round.
And because your requirements may change over time, we offer you full control of your heating system, DHW temperature and air change rates with our user friendly devices, intuitive apps, and SmartHome enabled programming units –so your living zone is also your comfort zone.
