Tank sensor

The buffer tank sensor (PT 1000) has to be installed at the corresponding position in the buffer tank. 
The measurement of the tank temperature is for information use only and has no influence on the control of the
boiler.

tank sensor

The buffer tank sensor should be installed after ⅔ of
the buffer tank volume.

tank sensor

Buffer tank 

(mandatory)

To improve the effificiency of the wood log boiler and to ensure low emission operation it is mandatory to use 
Solarbayer SPS buffer tanks with their patented SLS®‐system.

The advantages are:

‐ immediate availability of heat

‐ perfect stratification 

‐ rapid achievement of the required return line temperature for 

a long operating life.
