Swimming Pool<br />

Installation details<br />

To incorporate a swimming pool into the system it is essential that a suitable heat exchanger<br />

is used between the pool water and the circulating water through the manifold of the solar<br />

sy stem (Figure 21).<br />

Generally, wound coil heat exchangers should be used as they offer a big exchange area with<br />

a low pressure drop on the swimming pool side. This allows a high volume of pool water to<br />

be passed through the heat exchanger.<br />

It is necessary that the filtration pump is always ON when the solar collector pump is running<br />

to avoid overheating of heat-exchanger and pipework parts on the secondary side of the system.<br />
