TYPES OF POOL WATER HEATER

So you are getting ready to purchase a swimming pool heater and want to know which is best for you. This is a common problem for many people because there are so many types of heaters  available. We are going to try and explain different types of swimming pool water heaters that are present in the market. They are usually differentiated based on the energy source they use to heat up the water. Below is the information on different types of swimming pool water heaters, hopefully it will help you make an informed decision.

Electric Resistance Heaters
Electric resistance heaters use electric currents to create heat. When a current is applied to the resistor located inside the unit, the resistor heats. Water then washes over the resistor and heats, causing the resistor to cool. Because electric resistance heaters require large amounts of electricity, they are primarily used to heat small, portable spas and small therapy pools.

Gas Heaters
Gas heaters burn either natural gas or propane to create heat. Gas burns inside a combustion chamber, which contains a series of copper coils. As the gas burns, water passes through the coils and heats. Gas heaters have historically been the most widely-used swimming pool heaters, though their popularity is decreasing due to high gas prices and the advent of and efficiency of heat pumps.

Heat Pumps
Heat pumps use electricity to transfer heat to your swimming pool. Air-source heat pumps transfer heat from the air, and water-source (geothermal) heat pumps transfer heat from water. You can click here to learn how air-source heat pumps work, and here to learn how water-source heat pumps work. Because of their energy-efficiency, heat pumps have rapidly grown in popularity.

Solar Heaters
Solar heaters use solar panels to transfer heat from the sun to your swimming pool. As solar panels sit in the sun, they collect heat. Then, the swimming pool pump pushes water through the circulation system and through the solar panels. As the water passes through the solar panels, it heats. Because of solar heaters’ reliance on the sun, many swimming pool owners use auxiliary heaters during nights and cloudy days.
