Truma AquaGo On-Demand Water Heater

What is the best tankless water heater? Truma hailing from Germany debuted in the United States several years back, and it may be the best on the list. Their on-demand tankless water heater propane relies on propane and necessitates 12V DC power for electronic operations. This fun autopart can stir you up with two particular functionalities titled “eco” and “comfort.”

Of note, Truma’s AquaGo On-Demand heats only the quantity of water used. Also, a minor tank blending and pre-warming of the water to ensure rapid heating when necessity strikes are far out.

The two modes prove advantageous for conserving propane or minimizing water consumption. When boondocking – mobile camping without amenities – the “comfort” mode proves optimal as it economizes on water through pre-heating in its compact mixing tank. Lastly, Truma’s heater only heats necessary amounts of water rather than maintaining a full-filled tank always heated up, reducing your RV’s overall weight to a tee.

Granted, a drawback of Truma lies in its ‘pro-only’ installation process – you would need to visit an official store location or request a mobile technician from Truma for proper installation.
