## Questions & Answers

**Q: Does this heater come with any warranties?**
A: Theoretically, yes, BUT getting Hayward to honor them is very, very, VERY nearly impossible.  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
