Comprehensive Guide to Various Pool Heating Options
Choosing the right pool heating system is a significant investment. With numerous options available, this guide outlines the different types of pool heaters to help you determine the best fit for your needs. Understanding these options ensures you make an informed purchase for efficient and cost-effective heating. Below are the major types of pool heaters.
Electric Resistance Heaters
Electric resistance pool heaters generate warmth by passing electric current through resistors inside the unit. Water flows over these resistors, absorbing heat before returning to the pool. These heaters are popular for small pools and spas, especially for therapy or portable pools, due to their high electricity consumption.
Gas-powered pool heaters utilize natural gas or propane to generate heat. Combustion within a chamber heats water circulating through copper coils. Although once the most prevalent choice, their popularity has decreased due to rising fuel costs and the emergence of more efficient alternatives like heat pumps.
Heat Pump Systems
These heaters transfer heat into the pool using electricity, removing the need for fuel. Air-source heat pumps extract heat from the surrounding air, while water-source (geothermal) heat pumps draw heat from the water itself, offering eco-friendly heating solutions.
Solar Pool Heaters
Solar heaters harness energy from sunlight via solar panels installed in sunlit areas. Water is pumped through these panels, absorbing heat before returning to the pool. During cloudy days, many pool owners supplement solar heating with secondary systems to maintain consistent water temperature.
