Product description

The buffer cylinder vessel is delivered fully assembled.
The thermal insulation and temperature sensors have to
be fitted.
There are two types of buffer cylinder
( Fig. 4, page 52).
• Buffer cylinder
– BST 500-1000/80 Sr
– BST 500-1000/120 Sr
• Solar buffer cylinder
– BST 500-1000/80 SrSE
– BST 500-1000/120 SrSE
Both types of cylinder are available with 80 mm PU
flexible foam thermal insulation or 120 mm polyester
fleece thermal insulation.
The buffer cylinder is made from steel and equipped
with a temperature-sensitive return feed.
A back boiler or solid fuel boiler can be integrated via the
connections for the boiler and heating circuits.
The BST solar buffer cylinder additionally has a
connection for a solar thermal system and an electrical
immersion heater ( Fig. 4, page 52).

Correct use

Due to their large volume, the BST buffer cylinders and
BST solar buffer cylinders are designed for central
heating backup.
6 720 800 379 (2011/03)
These buffer cylinders may only be filled with heating
water and used in sealed heating systems. The cylinders
are not suitable for use with potable water.
The buffer cylinders can be used for indirect DHW
heating via a freshwater station.
2.4 Tools, materials and auxiliary
equipment
A pallet truck, forklift truck or crane is required for
transportation.
