Pool heating provides more enjoyment and comfort to swimmers. But since pool heating can add up to high heating bills and consumes a lot of energy, pool owners should use energy-saving pool heating systems such as solar pool heaters.
Answers for USA, Canada and countries running a 60 Hz power supply service. Well, you can run a 10/3, if that's what the unit calls for. If the pool heater equipment/motor only call for a 30 amp feeder you're away. I think this would be a bit light myself. You would have to tell me what the p…

I think you should just adjust to the temperature of the water.I am a nationally ranked swimmer and I like the pool at 68-73 degrees.At a temperature of 82, you should only be in the water for 25-30 minutes. I don't know how long you plan on swimming, but even 82 degrees to me sounds way to warm. I …

Based on your question, I will assume that there is nearly no elevation difference between the pool and the pump locations. Given this, the only factor in the max pipe length of a horizonal run is the friction of the water on the pipes. In this application, your pump has to do two jobs: 1) move …
