Elegir el intercambiador de calor correcto es muy importante para asegurarse de que la piscina llegue rápidamente a la temperatura deseada. Los problemas principales para considerar al elegir un intercambiador de calor de piscina son:

1. Pool size – what is the water capacity? Heat exchangers are sized according to capacity, so a unit designed to heat a 80 m³ (18,000 gal) pool would be no use, if you have an 180 m³ (39,500 gal) pool.
2. ¿Cómo se calienta? Suele elegirse entre una caldera y la energía renovable. Si se trata de energía renovable, elija un intercambiador de calor especialmente diseñado para el agua a menor temperatura que proporcionan los paneles solares o las bombas de calor, ya que estas unidades necesitan menos energía para llevar el agua de la piscina a la temperatura requerida.
3. Boiler water temperature – however, most pools will be heated by boilers, so what is the temperature of the boiler water? Usually, it’s between 80 °C and 85 °C – the ideal temperature for pool heating. Some boilers are lower – around 60 °C. So, using 82 °C water, a heat exchanger providing 110 kW should heat your 180 m³ pool efficiently. But if the boiler water temperature is only 60 °C, the heat available to transfer drops to around 60 kW – a reduction of over 40%, so a larger heat exchanger would be required for the pool to achieve full temperature.
4. What are the water flow rates? Flow rates are vital for the heat exchanger to transfer thermal energy to the pool. If the hot water flow rate is too low, the available energy will not be passed through the heat exchanger. However, the flow rate of the pool water is equally important. People often think it is important to generate a large temperature differential between the pool water entering and leaving the heat exchanger. They are happy, if the pipework connected to the outlet of the heat exchanger is noticeably warmer than it is at the inlet. In reality, this actually reduces the efficiency of the heat transfer process! This is because the pool water flow is too low – the water remains in the heat exchanger for too long, so a much smaller volume of water is being heated to a slightly higher temperature. Si embargo, con tasas de flujo más grandes, el tiempo que toma rotar el agua de la piscina se reducirá e incluso un pequeño incremento en la temperatura del agua de la piscina a través del intercambiador de calor (1,5 °C por ejemplo) tendrá un impacto mayor en la eficiencia del calentamiento de la piscina.
