Review: . Review: Really works! ## Features - SOLAR POOL HEATER – The Sunheater Solar Pool Heating System allows you to capture free heat from the sun’s rays to effectively raise your pool water temperature. It’s an efficient and cost-effective method to heat your aboveground pool. - EXTENDS POOL SEASON – Your pool’s pump pushes the water through the panel’s many tubes where it’s warmed by the sun and then returned to the pool. This system can raise the water temperature up to 15°F and extend your pool season by weeks! - EASY TO INSTALL – This solar pool heater uses your existing filtration system & comes with the necessary plumbing fixtures to connect to a rigid wall aboveground pool using flex hoses (hard plumb installations will require additional parts not included). - TUBE-ON-WEB DESIGN – The tube-on-web design allows Sunheater to capture the most sun possible, maximizing square footage. It offers rigid flexibility, allowing panels to expand and contract with changing temps, giving it the strength needed to last. - DIMENSIONS – This Sunheater Solar Pool Heater System includes two 2’ x 20’ panels (80 sq. ft) and is perfect for heating aboveground pools that measure up to 31’ round or 18’ x 36’ oval. ## Technical Specifications | Specification | Value | |---------------|-------| | Color | Black | | Material Type | Polypropylene | | Number of Items | 1 | | Included Components | 2-2x20 Solar Collectors; Instruction Manual | | Batteries Included? | No | | Brand | SunHeater | | Manufacturer | SPQ Brands | | Item model number | S421P | | Product Dimensions | 121.92 x 2.54 x 609.6 cm; 13.15 kg | | ASIN | B004VU986W | ## Images ![SunHeater Aboveground Pool Heating System, Includes Two 2’ x 20’ Panels (80 sq. ft.) – Solar Heater Made of Durable Polypropylene, Raises Temperature Up to 15°F – S421P, Black - Image 1](https://m.media-amazon.com/images/I/91Uvi0cf+rS.jpg) ## Questions & Answers **Q: what all is included in the purchase? hoses? clamps?** A: I purchased the kit with 2 solar panels. It comes with pvc caps for one end of the panels. A rubber hose to connect the two panels together on the other end, as well as hose clamps. 2 pvc fittings for input and output flow to the panels. These are made to connect the filter hose to the panels. (although we bought new fittings to use all pvc pipe) It doesn't have any mounting hardware or rack to mount the panels to. So don't expect to have everything you will need. The picture on this ad shows more than what you will get. But performance of this heater has been very satisfying **Q: Did you use one or two panels?** A: We used 2 panels **Q: can this be used to heat a [4 person] hot tub to a comfortably HOT temperature??** A: No. It only increases the temperature 6-10 degrees. If the water is hot then it may retain the heat & increase a little but would not be good as a main source of heat. **Q: What is the maximum amount of gallons that this pool heater will warm up? Also, by how many degrees?** A: 1 box of the S421P panels will heat up to 31ft round aboveground pool or 18'x36' oval pool. It can heat it up to as much as 15 degrees.
