Ground source heat pump (water)
BWW-1

Yield energy with the utmost efficiency directly from water.

The best thing about environmental energy is that it is freely available. WOLF ground source heat pumps (water) use energy from groundwater. Even at temperatures of 8 to 12 °C, it is still possible to extract energy from water with a heat pump. In an ideal scenario, you can draw up to 80 percent of the thermal energy required for your detached house from water.

It also scores top marks when it comes to its energy footprint. The BWW-1 works with particularly high efficiency, achieving a COP of approximately 5.5, which means that more than five times the electrical energy consumed is delivered to your heating system or DHW system. This represents energy efficiency class A++.

The near silent ground source heat pump (water) is very easy to set up and takes up little space. It takes up less than half a square metre in your hobby or boiler room. The integral heat meter continuously shows the output energy and helps you monitor the system's efficiency over the long term. You can control the BWW-1 directly with the BM programming unit or conveniently via smartphone, laptop or your PC at home.

The BWW-1 can be combined with various WOLF DHW cylinders. We especially recommend using it as a compact centre combined with the CEW-1-200. Incidentally, grants* are available for the BWW-1.(For further information, see Subsidies)

  • Short Info
  • Specification
GROUND SOURCE HEAT PUMP (WATER) BWW-1

Energy from water. Excellent efficiency.

The WOLF BWW-1 yields energy by extracting it from groundwater. However, the BWW-1 will require access to groundwater. The near silent unit is available with five different heat output ratings. Of course, it can also be combined with various WOLF DHW cylinders.

  • Awarded the EHPA quality seal for heat pumps. This guarantees highest product quality and energy efficiency, as well as a comprehensive customer service package
  • The perfect appliance for every demand: the BWW-1 is available in five different heat output ratings of 7, 11, 13, 15 or 21 kW
  • Can be combined with various WOLF DHW cylinders. The pump also has an ECO mode for particularly energy efficient DHW heating
  • Space saving thanks to compact dimensions: the unit takes up less than half a square metre of space
  • Very quiet operation thanks to highly sound-proofed casing
  • Always the right temperature: can be combined with the BKM cooling module to lower the room temperature via an underfloor heating system
  • Particularly energy efficient as a system when combined with a solar thermal and/or photovoltaic system. In this case, the energy required for heating the interior and hot water is generated – to a large extent free – by the sun
  • Benefit from public subsidies for heat pumps. More information can be found on our Subsidies page

Make your home a feel good zone
HEALTHY LIVING IN A PERFECT INDOOR ENVIRONMENT

BWW-1 ground source heat pumps (water) create sustainable and pleasant warmth so that you live at ease.

The perfect indoor environment depends on the temperature being just right. Degrees are critical, when it comes to feeling good. Environmentally responsible WOLF ground source heat pumps (water) are particularly well suited for heating. But this does not mean that you can only rely on the BWW-1 during the cold season. In summer, this heat pump also makes a major contribution by cooling the indoor air via your underfloor heating system and the BKM cooling module, with which it can be combined. So your house is an all-year-round feel good zone, with temperatures that suit you and your needs.

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.
