You’ve probably come across the term “heat exchanger” if you’ve been reading and researching ways to heat your pool. A swimming pool heat exchanger uses hot water from a boiler or a solar-heated water circuit to heat the pool water. Heat is transferred via conduction through the exchanger materials that separate the mediums in use.
Pool Heaters are useful in a wide range of pool and water applications, such as salt water and chlorinated swimming pools, Jacuzzis, Whirlpools, Spas, and Hot Tubs, Solar heated pools, Sea Water applications, Hot Climate applications, Domestic Hot Water Supply and Waste Water Heat Recovery. This means that whatever your reason for looking at pool heaters options, there will be one that is suitable.
Benefits of Pool Heaters
1) Corrosion occurs in both chlorinated and saltwater pools. If your heat exchanger is made of corrosion-resistant materials, it will last for a very long time.
2) Nobody wants to be bothered with extra upkeep. Check that the heat exchanger can handle a high flow rate. If the flow rate is high, your pool heaters will require very little maintenance and will last a long time.
3) If your heat exchanger has wide channels, it will take much longer to build up any hard water scales, resulting in a longer life span for your heat exchanger. Heat exchanger efficiency can be defined in a variety of ways, and there are several options in terms of thermal performance.
4) In a pool heater, the temperature difference between the hot fluid and the coolant is critical. Always keep the coolant at a lower temperature than the hot fluid. Lower coolant temperatures absorb more heat from hot fluid than higher coolant temperatures.
5) A higher flow rate increases the exchanger’s ability to transfer heat, but it also means more mass, which can make it more difficult to remove energy while also increasing velocity and pressure loss.
6) The heat pool heaters always be installed by the manufacturer’s instructions. The most efficient way to install a heat exchanger is with the fluids flowing in a counter-current arrangement (so that if the coolant is travelling left to right, the hot fluid is travelling right to left), and for shell and tube heat exchangers, the coolant should enter at the lowest inlet position to ensure that the heat exchanger is operating efficiently. When installing a cooler for an air-cooled heat exchanger, it is critical to consider the airflow; any part of the core that is blocked will reduce cooling capacity.
There are different types of pool heaters like natural gas or propane, electric spa & hot tub heaters, Solar panels, Solar blankets, etc.
When choosing a pool heater, always choose one that is rated slightly higher than your actual pool surface area and desired temperature rise. It is not possible to “oversize” a pool heater. The higher the BTU output of the pool heater you purchase, the faster it will heat the water in your pool. This results in less heater run time and a longer overall heater life span. You’ll be glad you went with the larger pool heater.
