2.1 Intended use
This appliance is designed to extend the operating time of the heat generator and to bridge power-OFF periods. The heat pump buffer cylinder also provides hydraulic separation of the flow rates in the heat pump circuit and the heating circuit.
Observation of these instructions and of instructions for any accessories and other system components used is also part of the correct use of this appliance.
Any other use beyond that described shall be deemed inappropriate. Using the appliance for heating fluids other than water or for water supplemented with chemicals, such as brine, is also deemed inappropriate.

Appliance description

The steel cylinder with directly applied foam insulation is equipped with a protective cover, connections for ventilation and draining, and a sensor pipe. The hydraulic connections are routed through the top.

Appliance description

6.1 Standard delivery
The following are delivered with the appliance: – 3 adjustable feet


7.1 Installation site

  • Always install the appliance in a room free from the risk of frost.
  • Ensure the floor has sufficient load-bearing capacity and evenness (see chapter “Specification / Data table”).
  • Observe the room height and height when tilted (see chapter “Specification / Data table”).

Minimum clearancesTIEBEL ELTRON SBP 100 Classic Heating Buffer Cylinder - fig 1


8.1 Positioning the equipment
Use the adjustable feet provided to compensate for any unevenness in the floor.

  • Undo the 3 screws from the non-returnable pallet.
  • Tilt the appliance and screw the 3 adjustable feet provided into the appliance.
  • Lift the appliance off the pallet.
  • When installing, observe minimum clearances (see chapter “Preparations / Installation site”).

8.2 Heating water connection
Material losses
Carry out all water connection and installation work in accordance with regulations.

  • Observe the heat pump operating and installation instructions when making the heating water connection.
  • Connect the hydraulic connections with flat gaskets.

Oxygen diffusion

Material losses
Avoid open heating systems and plastic pipes in underfloor heating systems which are permeable to oxygen.
In underfloor heating systems with plastic pipes that are permeable to oxygen and in open vented heating systems, oxygen diffusion may lead to corrosion on the steel components of the heating system (e.g. on the indirect coil of the DHW cylinder, on buffer cylinders, steel heating elements or steel pipes).
Material losses
The products of corrosion (e.g. rusty sludge) can settle in the heating system components and can result in a lower output or fault shutdowns due to reduced cross-sections.


9.1 Initial start-up

  • Fill and bleed the appliance (see chapter “Specification / Dimensions and connections”).
  • Carry out a tightness check.

9.1.1 Appliance handover

  • Explain the function of the appliance to users and familiarise them with its operation.
  • Make the user aware of potential dangers, especially the risk of scalding.
  • Hand over these instructions

9.2 Recommissioning
See chapter “Commissioning / Initial start-up”.
10. Shutdown
f Drain the appliance. See chapter “Maintenance / Draining the appliance”.
11. Maintenance
No special maintenance is required for the appliance. A regular visual check is sufficient.
11.1 Draining the appliance
Risk of burns ICON WARNING Burns Hot water may escape during draining.
If the appliance needs to be drained for maintenance or to protect the whole installation when there is a risk of frost, proceed as follows:
Drain the appliance using the appliance drain connection (see chapter “Specification / Dimensions and connections”).
