Solar pool heater is an effective way to reduce the cost of swimming pool heating, before the main gas heater, heat pump heater, electric heating, the use of high cost, with the development of solar energy, solar pool heater is one of the most cost-effective way of solar energy utilization.

1. Composition of solar pool heating system

1.1 Solar collector:

Mainly absorbs solar radiant heat and transfers the resulting heat energy to the heat transfer device, which is the key component of the solar heating system.

1.2 Heat storage tank:

The heat storage tank is to ensure the stable operation of the solar heating system, and store the heat of the solar collector, and then transfer the heat of the hot water stored in the hot water tank to the pool water. (The height of the storage tank should not be higher than the solar collector)

1.3 Collector piping:

Mainly to ensure the formation of a complete circulation system between the collector and the thermal storage tank, and set up the pipeline connecting the collector and the thermal storage tank.

1.4 Auxiliary heat source:

Solar heating is not a stable system, the need to make up for the uneven working conditions of solar heating, to provide supplementary heat non-solar heat source.

1.5 Control system:

There are temperature sensors, pressure sensors, solar radiation sensors, safety valves and so on.

1.6 Heat storage circulating water pump:

In order to fully absorb solar thermal energy and ensure the water temperature of the storage water tank, to realize the collector and the heat storage water tank to circulate between to obtain solar thermal energy power device.

1.7 Filter:

Heat storage circulating water pump to remove debris before entering the collector.

1.8 Flow Control Valve:

An automatic or manual device that transfers pool water through the solar collector.

2. The working process of solar pool heater

2.1 Using the heat storage circulating water pump through the filter

The heat storage circulating water pump passes the water in the swimming pool through the filter, removes the debris from the water and then sends the water to the solar collector.

2.2 Solar collectors heat the water

After the water passes through the filter, it will be directed to the solar collector for heating, the principle is to use the flow of water to take away the heat generated by solar radiation obtained from the solar collector panels, so that the water is warmed up.

2.3 Water returns to the pool

After the water is heated, the water is returned to the swimming pool. This process will continue until the pool reaches a temperature suitable for swimming.

2.4 Automatic control operation

In order to ensure the normal operation of the system, solar radiation sensors and water temperature sensors are usually installed in the solar system to realize the automatic control operation of the solar system. If the water temperature sensor detects that the water temperature is not in the set temperature range, it will send a signal to the controller to let the solar energy system work, if the water temperature sensor detects that the water temperature is in the set temperature range, regardless of the solar radiation situation, the heat storage circulating water pump will stop working.

If the solar radiation sensor detects that there is enough solar radiation heat, it will automatically turn on the heat storage circulating water pump, if it detects that there is not enough solar radiation heat, it will turn off the heat storage circulating water pump.

3. The role of auxiliary heat source

Auxiliary heat source and solar energy system for linkage, to realize the solar heating system in the absence of solar radiation or solar radiation heat is not enough, open the auxiliary heat source to give supplement or direct supply.

Conclusion

Solar pool heaters are very suitable for your swimming pool, you can not only reduce the cost of using electric heating but also protect the environment. A solar pool heater is more of an upfront investment, but it is worth it in the long run.
