Front

Differential temperature controller

Back

Regulates the system based on temperature differences.

Front

Auxiliary heat source

Back

Provides additional heating when solar energy is insufficient.

Front

Function of the heat transfer fluid in flat plate collectors.

Back

The heat transfer fluid circulates around the collectors and is heated directly by the sun.

Front

Function of flow tubes in flat plate collectors.

Back

Flow tubes allow the heat transfer fluid to circulate around the collectors.

Front

Evacuated tube collectors use solar energy.

Back

Solar energy is absorbed by the evacuated tube.

Front

The heat exchanger in the system is small.

Back

It plays a crucial role in concentrating heat.

Front

Connection of DTC sensors

Back

Connected to the solar collector and hot water cylinder.

Front

Pump activation by DTC

Back

Occurs when there is sufficient solar energy and hot water demand.

Front

Pump deactivation by DTC

Back

Happens when the hot water cylinder reaches the desired temperature.

Front

Circulating pump control

Back

The pump is controlled by the DTC and circulates the heat transfer fluid between the collector and the coil.
