Hey Jason, welcome back! For replacing the Suburban tankless water heater in your 2023 Jayco Jay Flight, I definitely recommend the Furrion RV Tankless Water Heater # FR98SR. This is one of my favorite options because it gives you a continuous supply of hot water without having to wait for a tank to heat back up. It's also designed to fit a 12-3/4" wide x 12-3/4" tall x 23-1/2" deep opening, making it a great replacement option as long as your existing cutout and available space match those dimensions.

Another thing I really like about the Furrion is its 60,000 BTU heating capacity and built-in freeze protection, which help make it a solid choice for camping in different conditions. It also comes with a wall-mounted controller so you can adjust the water temperature right where you want it. You'll need to connect the existing propane, water, and 12V electrical lines, and some modifications may be necessary depending on your current Suburban setup.

Has your Suburban been giving you that E1 error since you bought the camper, or did it start happening after it had been working fine for a while?

It has always given that error and I have tried everything to keep it from doing that. Other camper and other tankless heaters I have had did not give me this problem. I need one that will work right. Also does this heater have a flow adjustment knob ?

@JasonU Yes, the Furrion unit does have a flow adjustment knob.

@JasonU they are easy to install. i tested it after I installed it it worked great. Only thing about these heaters is make sure you drain it therally while winterizing. if you don’t it will damage the heat exchanger.
