What are the functions of solar water heater control probes?

1. Water tank temperature probe.

The main function of the water temperature probe on the water tank is to detect the water temperature of the water tank to determine whether the electric heating of the water tank is activated. When the water temperature is lower than the set lower limit temperature, the electric heater system will automatically start. Heating will automatically stop.

2. Water tank water level probe.

The main function of the water level probe is to detect the water level (water volume) of the water tank. When the water level drops to the lowest set water level, the water supply solenoid valve will automatically open to fill the water tank. When the water tank water volume reaches the highest set water level (water full), the water supply system solenoid valve is automatically closed to stop water supply. The relationship between the water level probe and the electric heater system is that when the water temperature of the water tank is low, the water level is also low, that is, the water tank has no water, and the electric heater system will not start. The probe can protect the electric heater against dry burning.

3. Collector temperature probe.

①The main function of the temperature probe of the collector is to detect the temperature of the collector and the antifreeze of the collector. The operation of the solar water heating system is controlled by the solar collector probe. When the temperature difference between the solar collector and the water tank reaches The temperature difference is activated, the solar circulating pump is activated, and the water tank is circulated and heated. When their temperature difference drops to the off temperature difference, the solar circulating pump is turned off to stop heating.

②The collector probe can also play the role of anti-freezing of the solar collector system. When the temperature of the collector is low to close to zero, the system circulation pump will automatically start to prevent freezing. In order to reduce heat loss and achieve the purpose of anti-freezing, The circulating pump will stop at about 15", which saves electricity compared to using pipeline electric heating cables.

4. Pipe temperature probe.

The pipeline temperature probe is a probe used for pipeline insulation, which is generally used in the upper and lower water pipelines to realize automatic control of insulation.

5. Water pipeline probe.

The water pipe probe is a control probe used for bathing water. Its function is when the bathing water pipe is too long and the shower nozzle cannot immediately produce hot water. In order to reduce the waste of water resources, a return pipe is added to the water pipe. The cold water of the water pipe is circulated to the water tank, so that the water pipe is full of hot water, and there is hot water as soon as the nozzle is turned on.
