Why not install continuous comfort?
Why not install something that delivers consistent CONTINUOUS comfort?!
Truma water heaters are widely regarded as one of the best on-demand systems on the market. With advanced temperature regulation and proven reliability, it’s easy to see why so many RV owners choose them. It’s the only water heater I want to install.
If you want a dependable hot water system that provides continuous hot water, without pressure adjustments or unexpected cold spikes, this is a strong option.
Truma AquaGo vs Traditional RV Water Heaters: What Actually Makes It Different?
RV water heaters usually fall into two categories: traditional tank systems and newer tankless designs. The Truma AquaGo blends elements of both approaches, which is why it stands out in the RV market. It’s not just “endless hot water” the real difference is how it manages temperature stability, delivery time, and overall user experience.
Endless Hot Water (Without a Storage Tank)
Traditional RV water heaters store 6–12 gallons of hot water and then must recover once depleted. The AquaGo heats water on demand using propane and 12V power, allowing continuous hot water as long as resources are available. This makes it especially useful for back-to-back showers or high-demand use.
More Stable Temperatures Than Typical Tankless Systems
Many RV tankless water heaters struggle with temperature swings when flow rates change. The AquaGo uses a controlled burner system and internal stabilization design (mixing vessel) to reduce those fluctuations. The result is a more consistent shower experience compared to many basic on-demand systems.
Faster Hot Water with Comfort Mode
In Comfort mode, the AquaGo keeps a small volume of warmed water ready inside its internal system. This reduces wait time at the faucet and helps smooth out temperature delivery when demand starts. Plumbing distance still matters, but users typically experience faster hot water compared to cold-start tankless systems.
Smaller Footprint, More Space Efficiency
By eliminating a large storage tank, the AquaGo frees up valuable space inside the RV. This allows manufacturers and owners to gain flexibility in layout while still maintaining continuous hot water capability.
Cold Weather Operation (With Limits)
The AquaGo includes built-in freeze protection features when properly powered. However, it is not freeze-proof, and standard RV winterization procedures are still required in freezing climates.
Propane Use and Efficiency
Because it heats water only when needed, the average consumer finds the AquaGo to be efficient during normal camping use. Actual propane consumption varies based on shower length, ambient temperature, and operating mode.
Propane Usage (Demand-Based vs Standby Cycling)
Traditional RV tank water heaters continuously cycle on and off throughout the day to maintain stored water temperature. Even when no hot water is being used, propane is still consumed to keep the tank heated.
The AquaGo works differently:
In ECO mode, propane is only used when hot water is actively flowing
In COMFORT mode, the system adds a small amount of standby heating to reduce wait time
BTU Output (Modulating vs Fixed Burner Systems)
The Truma AquaGo uses a modulating propane burner, with output that varies depending on demand:
-Approximately ~20,000 BTU at lower demand
-Up to ~60,000 BTU at higher demand
Rather than running at a single fixed output, the burner adjusts in real time based on demand and not by running continuously to get a tank to a fixed temp.
