Stratification cylinder
BSP-W-SL

The BSP-W-SL stratification cylinder is specially designed for heat pumps and for the most efficient utilisation of solar energy – giving you heating energy and DHW provision at the highest level.

Alongside solar thermal systems, heat pumps are the most environmentally responsible appliances for providing DHW and central heating.
The WOLF BSP-W-SL stratification cylinder is specially designed for utilising these resources drawn from the environment. It can also be combined with all commonly used heat generators, such as oil, gas, wood or pellet boilers.

The BSP-W is ideal for use with a heat pump because its freshwater module, where the DHW is heated, is designed for very low temperatures, making heat pump operation particularly efficient. To ensure optimum utilisation of solar thermal energy, the cylinder is equipped with smooth tube indirect coils at the top and bottom. These make the very most of the sun's energy to heat the cylinder water. In brief, by combining a BSP-W-SL stratification cylinder, a heat pump and a solar thermal system you are creating a particularly sustainable system.

STRATIFICATION CYLINDER BSP-W-SL

The BSP-W-SL stratification cylinder enables integration of a heat pump into your heating system and ensures optimum use of your solar thermal system.

The BSP-W is ideal for use with a heat pump because its freshwater module, where the DHW is heated, is designed for very low temperatures, making heat pump operation particularly efficient. To ensure optimum utilisation of solar thermal energy, the cylinder is equipped with smooth tube indirect coils at the top and bottom. These make the very most of the sun's energy to heat the cylinder water.

  • Solar energy backs up your heating system by means of the stratification cylinder
  • Separating plates stratify the water inside the cylinder into different thermal zones and so significantly improve the solar yield
  • The stratification technology ensures that water is always drawn from the hottest layer. This means that energy losses are kept to a minimum, reducing costly reheating and thereby saving energy and protecting the environment
  • Two smooth tube indirect coils guarantee optimum use of solar energy
  • The freshwater module always provides the right amount of hygienic DHW to meet your current needs
  • Short throughput times and small amounts of hot water in the system prevent the growth of legionella bacteria
  • The thermal insulation is removable; this is particularly advantageous for retrofitting, as narrow basement entrances and rooms often make transportation and handling into the installation room difficult
  • Hydraulic components such as a freshwater module, up to two circuits with mixer (for radiators and underfloor heating) and a solar pump/valve assembly can be fitted directly to the cylinder, ensuring a clean look and clutter-free boiler room
  • The DHW circulation set is controlled by timer, thermostat or by opening the water tap, guaranteeing hot water immediately without a long wait
  • The single cylinder system prevents heat losses

THE MOST SUSTAINABLE SOLUTION FOR YOUR HOME
STORE ENERGY FROM THE SUN AND THE AIR

If you really want to do something for the environment without losing out on convenience, then opt for a solar thermal system, heat pump and advanced cylinder from WOLF.

Create your perfect indoor environment – with sustainable energy drawn from the sun and the air. The right stratification cylinder enables you to harness these energy sources as efficiently as possible. This is because the highly accurate temperature stratification in the cylinder is fully tailored to your required temperature, while also maximising your solar yield. The result is a pleasantly warm interior and sufficient hot water at all times, with the added benefit of knowing you are doing something positive for the environment.
