Before developing the Truma AquaGo, the company researched the U.S. RV market to discover that available on-demand hot water heaters tend to fluctuate water temperatures.
Because of this, RV buyers have become wary, and the market for tankless or on-demand water heaters has remained relatively small, according to a news release from the company.
To remedy the fluctuations, Truma engineers developed a method to deliver the constant water temperature that people want and need. Different from anything on the market, the Truma AquaGo temperature-stabilizing vessel is a patent pending technology that mixes the hot water from the heat exchanger with cooler buffer-water in the vessel.
A cyclone stream developed with help of finite element analysis ensures a perfect mixture and constant temperature before leaving the temperature stabilizer. Simultaneously, a microprocessor control system exactly adjusts the burner power in relation to the water outlet temperature to meet the target outlet temperature of 120-degrees as accurately as possible.
Both methods ensure a constant, even water temperature without the risk of scalding. Other systems lack the stabilizing vessel and deliver hot water straight from the heat exchanger, making it difficult to maintain constant and safe temperatures.
“The importance of this feature is reflected in our marketing message of providing instant, constant, and endless hot water,” said Elden Wood, Truma vice president of sales and marketing. “Instant and endless hot water is what people want, but without the ‘constant’ temperature RVers have turned away from the benefits of instant water heaters. So this is a key and revolutionary development that makes the Truma AquaGoTM stand out above the others.”
