Had I not bought from a retailer where I was able to reach a live person who then went to bat for me, I would have been left with Hayward shrugging and saying they had no warranty providers in my STATE. Seriously. (I have to say that, had I known then what I know now about Hayward propane heaters, I would have stayed with my prior electric pool heater and spent the money switching over my hot water heater to gas instead.) **Q: Is it worth the time and money to rebuild my 10 year old h250ped2 or buy a new one?** A: Buy a new one. They are so much more efficient. I worked on my old pool heater until it caught fire. The new one is so much safer and problem free. **Q: How long would the 150,000 BTU take to heat only our attached hot tub?** A: We heat our pool which is 26,000 gallons 1-2 degrees and hour. We are very happy with it! **Q: What is the Energy Star Rating for this pool heater?** A: Performed perfectly ## Frequently Bought Together - Hayward W3H400FDP Universal H-Series 400,000 BTU Propane Pool and Spa Heater for In-Ground Pools and Spas - 2 PACK -CMP Hi-Temp Union 2" inch 2MIP x 2" inch PVC Whisperflo & Intelliflo - 2 PACK - Hayward SPX3200UNKIT Union Connector Replacement Kit for Select Hayward Pump and Heater --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/147296514-hayward-h-series-propane-gas-pool-heater-for-inground-pools](https://www.desertcart.tn/products/147296514-hayward-h-series-propane-gas-pool-heater-for-inground-pools) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-09*
