"Called Robert Manna (the owner) about replacing our old pool pump and the job was completed 2 days later at a great price. Robert and his installers were a pleasure to work with and everyone I was in contact with was very knowledgeable and courteous. I highly recommend calling Solar X for all of your solar/swimming pool needs."

"My pool heater broke on Friday and I searched for pros quickly. I realized that most pool companies don’t work on the weekends but I tried. I sent a request for an estimate to replace my pool heater but needed it to be completed on Monday. The owner of Affordable Solar and Pool Heating replied on Saturday and provided me with an estimate and scheduled the replacement on Monday. The tech, Henry came on Monday. He was one hour earlier and replaced the heater. He was very knowledgeable, Courteous , neat and took the time to explain everything he had done upon completing the replacement. It was a great experience and I was extremely happy with the results. Their work ethics or great and they are very focus on customer satisfaction. I strongly recommend this company."

"We needed the pool refinished and some plumbing work completed. The job was done within expectations as the team did a good job explaining step-by-step what would be done/when. The finished product looks great, the team was polite, worked efficiently, cleaned up, and made sure I was happy with the result. Well worth the $."

"Our pool needed some TLC. Had last been redone back in the 90’s. The cement was flaking off of the sides & steps. We got Ronny’s name from a friend. Ronny suggested some very doable makeovers for our pools that fit our budget & our lifestyle. He was easy to work with. When we asked questions, he responded promptly via text or call, in language we understood. Our pool project was completely in a timely manner and they cleaned up. We’re very pleased."

FAQs for swimming pool heaters installation and replacement projects in Oldsmar, FL

Yes, you can add a heater to an existing pool. A pro can retrofit a heater to nearly any in-ground or above-ground pool. Adding a heater allows you to start the swim season earlier, finish it later, and maintain a steady water temperature in between. Many owners schedule the job during a larger pool upgrade, but it also works as a standalone project. Professional installation ties the new unit into the existing pump and plumbing for safe, efficient operation.

Most owners switch the heater on a day or two before they plan to swim, then shut it down afterward. Reaching the target temperature can take 24 to 72 hours, depending on pool size and outdoor conditions. Using a cover while the heater is off helps hold the heat and keeps energy costs in check.

Pool heaters can freeze if left exposed to extreme conditions. Freezing can damage internal heater components, potentially leading to costly pool repairs. Cycling water, covering the heater, and regular maintenance help prevent freezing. Sealing or winterizing your heater also protects it during the season—this involves draining water from the heater and its components.

Pool heaters operate with lifespans spanning from seven to 30 years. Gas and propane models last seven to 12 years, while electric and solar heaters perform efficiently for up to 30 years. Consistent professional maintenance and routine inspections extend the heater’s life and improve its performance, ensuring a safe and reliable heating system for your pool.

Before hiring a pool heater installation contractor, conduct thorough research by reviewing online feedback and gathering recommendations from trusted sources. Contact multiple professionals to discuss pricing, request references, and understand the complete installation process. This careful evaluation ensures you select a qualified contractor who delivers high-quality service and a successful installation.
