How we picked

This guide covers 9 solar pool heaters from the catalogue, all titled as solar heaters that pool water runs through: panels, collector kits, domes, and mats. The pool was built from listings with the solar use case. Picks are ranked by the number of stated details (type, BTU, pool, pool gallons, voltage, inverter, WiFi), then by stated BTU from largest to smallest, then by the order in the pool file. Products are compared on stated details and live prices only. The top pick is the SunLink Pro, which states both inground and above ground compatibility.

How to choose

Solar heater types in a listing

Solar pool heaters come in different forms: panels, collector kits, domes, and mats. The title tells you which type a listing is. For example, the Intex Solar Pool Water Heater Mat is a mat, while the Doheny's Solar Heating Systems for Above Ground Swimming Pools (2.5' x 20' Collector Kit) is a collector kit. Choose the type that fits your pool setup, but the title is the only source for this information.

Pool type: what the title names

Some solar heaters state they are for above ground pools, others for inground pools, and some for both. The SunLink Pro Solar Pool Heater DIY Kit states it suits inground and above ground pools, while the FAFCO Solar Bear states it is for above ground pools. If a listing does not state a pool type, the seller has not provided that detail. Match the stated pool type to your pool.

DIY kits and accessories

Many solar heaters are sold as DIY kits, such as the Highest Performing Design DIY Solar Pool Heater Kit. Others are accessories, like the High-Strength Woven Polyester Hold-Down Strap. The title tells you if a product is a kit or an accessory. Consider what you need: a complete system or a component to add to an existing setup.

BTU figures and what they leave out

None of the solar heaters in this guide state a BTU figure. The catalogue does not include heating output for these products. If you need a BTU figure, you will not find it here. The maker's sizing page and manual are where to look for that information, and a licensed installer can help you choose the right size.

Who installs and wires pool equipment

Solar pool heaters are part of your pool's plumbing and may require electrical work if they include a pump or controller. A licensed electrician should handle any wiring, following the maker's manual. For gas or electric heaters, a licensed installer is required. Always consult the manual and a professional for installation.

Rules to check before you buy: local code, permits and utility

Before buying a solar pool heater, check with your local building office and your utility. Local codes and permits may apply to pool equipment installation. Utility programs may offer incentives, but this guide does not cover them. The maker's manual and a licensed installer are the sources for what your area requires.
