Hot water is returned back to the pool.

Swimming pool water heating scheme
Heating of water in the pool can be done using any of the first three schemes given above.

Cold water from the bottom of the pool is supplied by a circulation pump through a cold water pipeline to a storage tank, boiler or buffer tank.

Forced circulation of water in the pool circuit ensures mixing of water and uniform temperature distribution throughout the depth of the pool.

For pools that operate only in summer, the storage tank can be excluded from the heating scheme. The pool bath can act as a storage tank.

Automation of heating and hot water supply systems with a solar collector
Heating and hot water supply systems with a solar collector kenya mobile database be equipped with automatic control devices.

Automation is necessary for the coordinated control of the operation of several energy sources - a solar collector, a boiler, an electric heater, and circulation pumps.

The sensors measure the temperature of the coolant at the heating sources, the temperature of the water in the storage tank. The control unit analyzes the sensor readings according to a given program and issues commands to turn on or off certain heating sources, pumps and valves.

A person has the ability to set control parameters - for example, to set the maximum temperature of hot water.

Which solar collector is better to choose?
Each type of solar collector has its own minimum threshold of solar radiation intensity at which they begin to heat the coolant.

A flat solar collector begins to heat at a solar radiation power of 70-90 W/m2. For comparison, if a flat collector is not covered with glass, it will begin to heat at a radiation power of more than 200 W/m2.

Tubular solar collectors with vacuum tubes begin to heat the coolant at a radiation power of more than 20 W/m2.
