Heatexchanger for swimmingpools and spas

These heat exchangers provide a simple method of heating swimmingpool water indirectly from a central heating boiler

They should be installed downstream of the pumping and filtration equipment. The boiler water must be  pump assisted and the usual precautions taken to prevent air locks. This pump should be controlled by a thermostat in the pool water pipe before the heat exchanger and set at the required pool temperature.

Indicated performance capabilities of the heat exchangers, base on 12.5% of the pool water passing through the heat exchanger per hour and an initial temperature rise of 0.5 K per hour. Larger flow rates can be used up to the limit imposed by the port sizes.
For applications where the pool water comes from a solar system, we can supply longer heat exchangers to make the best use of lower temperature water from solar panels.
Pool water tends to become acidic when chlorination is used. The pH value of the water must be maintained between 7.2 and 7.8 and ideally between 7.4 and 7.6.

All our shell & tube swinningpool units have cupro-nickel 90/10 tubes to withstand the aggressiveness of swimming pool water.
As an alternative we can also offer brazed platetype heatexchangers

For use with sea water and therapeutic pools, we can, at extra cost, supply heat exchangers with resistant components.
