Buffer tank sensor: where it is placed and how it affects control

In systems with a buffer tank, the position of the temperature sensor directly affects when the heat pump starts and stops.

Upper part of the tank

Provides information on the hottest zone of the buffer.

Lower part of the tank

Can be used for charging control or for assessing the overall status of the tank.

Incorrect position

Can cause frequent start-stop cycles or delayed system response.

Correct choice

The position is determined by the manufacturer's logic and the specific hydraulic layout.
