Tankless water heater

Nothing in the jayco guide talks about winterizing a tankless water heater. The knobs for winterizing are based on a tank heater. So how do I winterize to get anti freeze through tankless heater?

Google is a great resource for RV questions. The best thing about it is you get videos that walk you through various issues.

Problem is that the jayco has specific settings for winterizing but not for girard heaters.

Nothing special, just drain the fresh water system normally run air thru the system, fill it with Red Pop and all is good

Understand but the idea is, use your parameters and try a search. Go to the web site for the brand you have and look up maintenance. That is usually how I find manuals that I don't have. A phone call to Jayco will probably get you directed to the data. There are a gazillion ways to find what you are looking for.


Do a search, using the search feature on this site is another option:

There are several more threads.

If you flip the winterized switches, it by passes the water heater. Therefore no air or antifreeze goes through it

Blow the lines before you flip to winterization. That's all with a Girard.

I bought Suburban unit to replace the original gas only unit that came with my 2005 camper. EASY install! EVERYTHING lined up perfectly- gas line, water plumbing, electrical. I had to run an AC line. Rather than go through walls, I wired in the recommended 14gauge via an extension cord. (For now). Most of all the immediate shipping and communication by Drock’s games and More allowed me the time to do the switch prior to our Colorado vacation departure. Customer service with the water heater manufacture (Suburban)was also incredible as I had questions about the gas portion of the heater at higher altitudes and found out about a higher altitude orifice and how to install it. Also added a 140 degree thermostat to make the hot water go further. Both upgrades cost a total of $30.

Yup, don't winterize, just replace your water heater every year......

Mine has a Girard tankless, I just pump the antifreeze through all the water lines including hot water lines. It goes through the heater when you do that. One thing I have always done is in the spring I hook up to the city water and run a lot of fresh water through all the lines before the water heater is ever turned on. Then I sterilize the fresh tank and pump that through the water heater as well. This insures the heater has had all the antifreeze removed and sterilized before use. Happy camping and God Bless!

Busted water pipe assembly

Got a call from a friend in our area with a leak in his Girard GSW-2 tankless. It had been stored in below freezing weather. He blew the pipes but did not have it power while stored. From the picture he sent it looks like the Water pipe assembly is ruptured from freezing.

I'm guessing a part like that can be sourced locally?

Has anyone had to replace a part and found it at a rv supply for these tankless units? I'll be checking around tomorrow. He says he can't see any way to turn the water off to it, so he has no water input to the rig.

I looked at the tankless in my previous post. It is a HT and has no way to bypass the water heater.

The Girard does have a heater that keeps it from freezing but his was stored without power. The water froze and busted the copper pipe on the heating assembly. We removed the pipes from the wh and bypassed it until they can order the part. It was easy to get to from under the sink.
