Our job
We help pool owners define the heating job before choosing a product. That means separating fast recovery from temperature maintenance, measuring gallons and surface area, checking the available utility service and respecting the effect of wind and evaporation.
How we research
We begin with manufacturer manuals, official specifications and government energy or safety guidance. Brand pages separate product families from exact models, while every calculator exposes its assumptions so a reader can challenge the result. Corrections are reviewed against the newest primary source we can identify.
What we are not
We are not an installer, engineer, gas fitter, electrician or warranty administrator. Our calculators are planning aids. Current manuals, local codes and qualified professionals control the final installation.
How the site is funded
Some links are affiliate links. If a reader makes a qualifying Amazon purchase, we may receive a commission without changing the reader’s price. Affiliate relationships do not buy placement or alter our conclusions.
