Purchasing a pool heater involves a big investment. Since there are several options available, this article throws light on the different types of pool heaters that will help you make the right choice in accordance with your needs and thus will help you make the best purchase. Here are the different types of pool heaters.
Electric resistance heaters
Electric resistance pool heaters create heat using electric currents. When a current is made available to the resistor that is positioned located inside the unit, it heats. It is then that the water washes over the resistor and heats, thus instigating the resistor to cool. Electric pool heaters are the most preferred choice which is known to warm the pool by first sucking in the water and then pumping it back in the pool. Since electric resistance pool heaters need a lot of electricity in order to operate efficiently, these pool heaters are best suited for therapy pools and other small portable pools and spas.
Gas heaters
Gas heaters typically operate on natural gas or propane in order to create heat. In such type of pool heaters, gas normally burns in a combustion chamber, which encompasses a sequence of copper coils. When the gas starts burning, water then passes through the coils and gets heated. Historically, gas pool heaters have been the most widely used, although their demand has seen a fall due to increased gas prices and also with the advent of more efficient heat pumps.
Heat pumps
Electricity is used by heat pumps to transfer heat to the swimming pool. Air-source heat pumps are known to transfer heat from the air. Geothermal, also known as water-source heat pumps, transfer heat from the water.
Solar heaters
Solar heaters are pool heaters that use solar panels for transferring heat from the sun to the swimming pool. When solar panels are placed in the position of sunlight, they pull together heat. It is then that the swimming pool pump thrusts water through the movement system and also through the solar panels. As the water passes through the solar panels, it heats up. Since solar heaters have the sun as the primary source of power many pool owners use auxiliary or secondary heaters during cloudy days.
