 | Swimming Pool Heat Exchangers Ref: heat
These heat exchangers provide a simple method of heating swimming pool 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 on the back page are the performance
capabilities of the heat exchangers based on 12.5% of the pool water passing through the heat exchanger per hour and an
initial temperature rise of 0.5oC 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 heat exchangers have cupro-nickel tubes to withstand the aggressiveness
of swimming pool water. For use with sea water and therapeutic pools, we can, at extra cost, supply heat exchangers with
bronze end covers.
