The water of the swimming pool can flow through the Solar-Aqua absorbers in either direction, so they can be mounted both lengthwise and side by side. The individual rows of absorbers are connected on a Tichelmann principle (same routes for each row). It is not advisable to connect more than seven absorbers in series.

DESIGN

Recommended absorber area in % of pool surface for open-air pools with cover or indoor swimming pools (early May through end of September) Temperature increase 4-7 °C compared to unheated swimming pools The absorber area should be chosen 50% larger if there is no cover. The regionally different number of sunshine hours can be allowed for by adding or deducting up to 20% absorber area.

Pump performance

The flow rate should be 150 to 250 l/m2 absorber area per hour. The required type of pump is easy to determine. The delivery rate is calculated from the absorber area x 200l. The delivery head is the difference in height between the water level and the absorber panel plus approx. 5 m.

Sola-Aqua solar absorbers of high molecular polyethylene offer the right foundation for operating such installations

Sola-Aqua - solar heating of swimming pools

The problem is familiar. An outdoor swimming pool that is not heated is only really comfortably warm for three or four weeks at the height of summer - very little when you think of all the investment and maintenance you put into it. An indoor swimming pool has to be heated all the year round, even in the middle of summer.

Heating a swimming pool using conventional means of energy can be a costly business and is also a load on the environment.

But the heating of swimming pools is an ideal application for solar energy. No very high temperatures are needed, but large quantities of water have to be heated, so it makes sense to operate such an installation with a large flow rate at a relatively low temperature level.

In that way your Sola-Aqua swimming-pool solar heating produces optimum efficiency

Different configurations of Sola-Aqua swimming-pool

solar heating.

1. Operation with filter pump via three-way motor ball valve with

difference-temperature regulation

This configuration can usually be selected if the absorbers are not to be set up higher than 6 m above the surface of the water. The three way

motor ball valve is integrated into the pressure line of the filter installation. Because of the difference-temperature regulation the ball valve is changed over when the absorber temperature is higher than the temperature of the water of the swimming pool. The filter stream is then pumped through the absorbers. The warmed water flows

back into the filter circuit by way of a Tee.

2. Operation with own pump and different temperature regulation integrated into filter circuit.

In many cases it may be sensible or even necessary to install a separate pump for the solar heating. For example when the delivery head from the water level to the absorber panel is more than 6 m. The water is diverted from the filter installation by way of a Tee and pumped through the absorbers by the auxiliary pump. This pump is switched by the difference-

temperature regulation to ensure that it only runs to actually win energy. The filter and solar pump are separately regulated. It is usually advisable to integrate non-return valves in both the solar and the filter circuit.

3. Operation with own pump and difference-temperature regulation -

piping independent of filter circuit

This configuration is chosen when the filter piping is difficult of access. The water is sucked out of the swimming pool by an immersion pipe, pumped through the absorbers, and the warmed water is conducted back into the swimming pool. Here too the difference temperature regulation ensures that the pump only runs to win energy. If the pump is mounted above the water level and the delivery head is more than 5 m, a non-return valve should be incorporated.
