Installation was not difficult for a DIYer. I primarily use the heater to heat up my hot tub not the pool, this heater is a lot smaller than the LT400 which I was concerned about. What I have observed is that it heats about 20% faster than the LT400. Very happy with the small size, it looks much better and give me more room on the equipment pad. Review: FAULTY MANUFACTURING - I bought this unit to replace a spa heater that was 20+ years old. I expected that I would enjoy a similar experience with Jandy that I'd already had. Well, sadly, that was not the case. Once the new unit was delivered and installed by our pool company, we enjoyed a number of evenings in our spa. The weather got cold and we waited for spring to use the spa again. Spring time came and went. So did summer. Fall came and we fired up the spa heater... and nothing. Checked pilot. Checked the temp setting. All OK. Called the pool company. They showed up the next day. Upon inspection they gave the bad news: The heat exchanger went out and that allowed water to get into the main heater and compromised all the electronics which caused the whole unit to fail. Nothing but rust was left. Nothing to repair or salvage. Now, if you are selling me a unit for $2400 and it is professionally installed and it worked from day one and it craps out in 18 months, then I attribute the failure to faulty manufacturing. One star is generous. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00OZWY0CS | | Best Sellers Rank | #1,464,146 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #701 in Swimming Pool Heaters | | Brand | Jandy | | Brand Name | Jandy | | Customer Reviews | 4.0 out of 5 stars 10 Reviews | | Form Factor | Cabinet | | Fuel Type | Natural Gas | | Heat Output | 399 KW | | Heating Element | Radiant | | Heating Method | Convection | | Indoor Outdoor Usage | Outdoor | | Indoor/Outdoor Usage | Outdoor | | Model Number | JXI400N | | Mounting Type | Floor Mount | | Number of Items | 1 | | Power Source | Gas Powered | | Recommended Uses For Product | Home | | Room Type | Patio | | Special Feature | Fast Heating | | Special Features | Fast Heating | | UPC | 720394863486 | ## Product Details - **Brand:** Jandy - **Form Factor:** Cabinet - **Indoor/Outdoor Usage:** Outdoor - **Power Source:** Gas Powered - **Special Feature:** Fast Heating ## Images ![Jandy JXI400N Compact Swimming Pool Spa Hot Tub Natural Gas Heater 400K BTU - Image 1](https://m.media-amazon.com/images/I/51LjXCoWsKL.jpg) ![Jandy JXI400N Compact Swimming Pool Spa Hot Tub Natural Gas Heater 400K BTU - Image 2](https://m.media-amazon.com/images/I/410ToT3zZ4L.jpg) ![Jandy JXI400N Compact Swimming Pool Spa Hot Tub Natural Gas Heater 400K BTU - Image 3](https://m.media-amazon.com/images/I/414tqfNTmSL.jpg) ![Jandy JXI400N Compact Swimming Pool Spa Hot Tub Natural Gas Heater 400K BTU - Image 4](https://m.media-amazon.com/images/I/51HQpEC4ISL.jpg) ![Jandy JXI400N Compact Swimming Pool Spa Hot Tub Natural Gas Heater 400K BTU - Image 5](https://m.media-amazon.com/images/I/515IoIVL9qL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice Heater *by R***Y on January 22, 2016* I replace my Jandy LT400 heater with the JXI400N.
