  • BSH high hygiene cylinder

    The BSH hygiene cylinder is a classic combination cylinder for solar thermal technology. It is also designed as a stratification cylinder for highly efficient use of a solar thermal system.

    The hygienic buffer cylinder heats your domestic hot water instantly using a stainless steel heat exchanger. The WOLF BSH is available in the variants BSH-500, BSH-1000, BSH-1500 and BSH-2000 with storage volumes between 500 and 2000 litres.

    Basic information

    BSH-500 diameter with thermal insulation 850 mm

    BSH-800 diameter with thermal insulation 1030 mm

    BSH-1000 diameter with thermal insulation 1030 mm

    BSH-1500 diameter with thermal insulation 1240 mm

    BSH-2000 diameter with thermal insulation 1340 mm

Benefits of WOLF stratification cylinders

Save costs

Optimum efficiency

Cut energy costs

Heating systems with buffer cylinders can run for longer stretches and use their heat generators less frequently. The stratification function of the BSP and BSH increases efficiency even further.

Domestic hot water in a flash

You benefit from a reliable and hygienic domestic hot water supply. And thanks to the large storage volume, you have a plentiful supply of hot water available to you in two shakes.

Happy family on the couch

Less wear

Longer service life

Reducing the number of burner starts minimises wear and tear on the heating system and increases its service life.

Minimal maintenance required

WOLF stratification cylinders do not usually require any special maintenance. And they last a very long time.

WOLF solar thermal

The perfect team

Perfect combinations

Stratification cylinders are the perfect partners for all heat generators. This is because gas condensing boilers, heat pumps and solar thermal technology alike benefit from efficient stratification in a cylinder.

No oversized elements

Stratification cylinders in modern heating systems keep down the size of the heat generators required.

Perfectly in tune with you.
