RV Water Heater Replacement – Girard vs. Truma, Tank vs. Tankless

For anyone else out there in RV-land stuck with a barely-working hot water heater, this post is for you!

Our hot water heater wasn’t functioning correctly from the very first day we had our Pleasure-Way Van. The first time we attempted to have it fixed we went back to our original dealer in Las Vegas where they replaced the Sail Switch. That got us by for a few days until it broke again, at which point we were in Lake Havasu City, Arizona.

At some point in this process we realized our existing hot water heater wasn’t going to work well for us, even once it worked as-designed.

Here’s the quick scoop…

The Girard GSWH-1M tankless hot water heater has several issues with it’s design. The Gas Modulation Control dial that adjusts the flame (and temperature of the water) must be adjusted constantly. It is recommended to set it “at the beginning of your camping trip” but when the temperature swings 20-40 degrees in a given day, in reality, it must be adjusted all day long throughout the day.

With the Girard, the water will only begin to heat once the water is turned completely to full blast, with hot water running completely open. Adding any cold water will make the emergency cut off switch turn the hot water heater off – and – it’s back to square one. The only way to use our water was to attempt to ONLY use the hot water faucet and adjust the temperature from the kitchen wall, without ever using the cold faucet (we learned this from reading forums).

Showers took a kitchen-assistant to attempt to keep water at a decent temperature by adjusting the Gas Modulation Control dial upon request of the person in the shower. Girard definitely wins the Rube Goldberg award for hot water systems…

Okay, enough about the Girard. Actually, one last thing – most people spend about a year trying to make it work before finally getting something else. We skipped right to the end of the line and decided to get the “something else” immediately.

Here’s the process we went through when we realized it was time to figure out what to do next… The 2016 Pleasure-Way Plateau TS has no ability to hold a 6 gallon water heater, or even a 4 gallon water heater anywhere on the chassis. There’s simply no room within the existing floor plan. We did want a working hot water heater, but we did not want to do any remodeling.

After extensive research, we discovered the Truma AquaGo (Basic) tankless water heater would fit in the same spot as the Girard, with limited surgery required to the van. The Truma also sounded like a better designed product.

Once we made the decision to go with the Truma AquaGo we searched their website for AquaGo dealers located across the region of the country we were in, or planned to be in (California, Nevada, Arizona, and Texas). We found several of interest, checked reviews online (Yelp was a huge help), and then called a few for estimates. Of the repair shops we contacted, only one was so familiar with the AquaGo that they were able to immediately give us a quote and talk knowledgeably about the product and installation required. They also provided the most reasonable quote!

McBride’s RV in Chino, California was our winner. And, they did a remarkable job!

The change from any factory-installed item to an aftermarket will likely cause a few snags here and there. For us, the main issue was the hot water heater door on the outside of the van that was designed for the Girard would not work with the Truma. We knew that was a possibility and we all hoped for the best, but – no luck. The venting needed by the Truma was in a different spot and it simply wasn’t going to work.

The downside of needing a new door meant a few new complications. The Truma door is white (our van is silver) and it has a frame around the door that if used, would stick out from the body of our van. It was unsightly at best, and possibly problematic.

Truma AquaGo

McBride’s tried several options beginning with altering the door we had, then adjusting the Truma door to be frame-less (after calling Truma to make sure that would not void our warranty). The frameless door turned out to be the best bet. If you look closely at the photo to the left, you can see the frame.

McBride’s included us every step of the way once there was a snag, giving us a choice and letting us participate actively in the outcome rather than be surprised or suffer from sticker-shock at the end.  Once everyone decided on a plan, the door needed some cosmetic adjustments. Namely, it needed to not be white!

McBride’s gave us a head’s up on the added cost of painting the door (got our approval), then got their onsite paint-matching guy to match the body paint we have. The added task of painting meant a little more time before we were ready to roll – but McBride’s had us covered. The let us stay on their lot (with water and electric hookups!) until the next day when the freshly painting door could be installed. They even gave us a walking tour of the shop and made sure we were totally comfortable before they departed for the night.

The next day, the newly-painted door was ready to be installed, and with that, we were ready to roll!

BEFORE Girard Water Heater

The photo on the left is the BEFORE picture from the body of the van, with our factory-installed Girard water heater.

It’s now been a few days and our water still gets hot when we turn the faucet to hot – something that feels like magic after a month without hot water.

For anyone in need of switching to a Truma AquaGo, though it’s only been a few days for us, I think I can safely recommend it. In a word, it works. You turn the water to hot, it heats the water. You can adjust the flow of water to be barely on and still get warm or hot water as desired (great for boondocking and those conserving water), and McBride’s is definitely a shop to consider. I’d happily have them do more work for using the future, it was definitely a 5-star repair experience!

AFTER Truma AquaGo Water HeaterThe photo on the right is the AFTER picture, with the Truma AquaGo, minus the frame – and – painted to match our van. McBride’s spent time giving attention to detail to make this work for us, and they did a great job.

And, now we have hot water. It’s very strange I tell you, strange indeed.
