The Costway Solar Pool Heater is a dome-shaped solar collector that sits beside the pool and uses a transparent cover over black coils to warm water pumped through it. It needs no electricity or gas, and the two foldable legs let you tilt it toward the sun and fold flat for storage. It suits owners of small above-ground or inground pools who want modest, low-cost warming without plumbing a full solar array. Against panel-style solar heaters it is simpler to set up and move, but it adds less heat and works only in direct sun.

Buyers give it solid marks overall, with most praise for easy setup and the no-power design. Complaints center on modest heat gain and dependence on strong sun.
The Costway Solar Pool Heater is a dome-shaped solar heater for above ground and inground pools. It runs on sunshine and needs no electric or gas connection. A transparent dome cover and built-in black coils work together to absorb and hold heat. It usually raises pool water temperature by 5.4 to 7.2°F.
Two wide, foldable legs let you angle the heater toward the sun and keep it stable in use. With the legs folded, the dome takes up less space in storage. The 90° rotatable hose connectors make hose setup easier. Up to 3 heaters can be linked to heat a larger pool.
The set includes hoses, connectors and fastening accessories for connecting the heater to a pool.
