Stratification cylinder
BSP-W

The BSP-W stratification cylinder enables integration of a heat pump into your heating system and is optimised for use with an additional 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. In brief, by combining a BSP-W stratification cylinder, a heat pump and a solar thermal system you are creating a particularly sustainable system.

• Solar energy backs up your heating system by means of the stratification cylinder
• 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
• Separating plates stratify the water inside the cylinder into different thermal zones and so significantly improve the solar yield
• 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 assembly in 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
