Buying Guide: Key Considerations for Solar Pool Heating
- Pool size and type: Above-ground vs. in-ground and total gallons guide which heater size and number of mats or panels you’ll need.
- Sun exposure: Solar heaters perform best with full sun; consider roof placement or unobstructed ground positioning.
- Pump compatibility: Many systems require a minimum pump power and a maximum flow rate; verify your pump specifications before purchase.
- Portability and storage: Roll-up panels and inflatable mats offer portability, while fixed mats and panels deliver more sustained heat.
- Maintenance and durability: Look for weatherproof materials, UV resistance, and ease of cleaning to maintain efficiency.
- Cost vs. benefit: Consider upfront costs against potential energy savings and extended swimming season needs.
