In a significant advancement for the energy sector, researchers have delved into the complexities of hot water treatment in autonomous heat supply systems, particularly those with multiple water intake points. This study, led by A. L. Toropov from the Engineering Center “April,” addresses a common issue faced by households and businesses alike: the comfort of hot water consumption in environments where multiple taps may be in use simultaneously.
The research highlights the challenges associated with gas heaters, specifically the delays in hot water delivery and temperature fluctuations that can occur when two water intake points are activated at the same time. As Toropov noted, “The operation of autonomous hot water supply systems with several water intake points leads to water temperature fluctuations with a range of up to 10 °C. This can significantly impact user comfort and energy efficiency.”
Conducted at the research stand of the “ARDERIA” plant, the study focused on various gas instantaneous water heaters, including the Ariston FAST EVO ONT C 14 and Arderia D24 models. The researchers meticulously measured the thermal inertia of the heat exchangers and observed how different modulation algorithms affected water temperature, particularly during the simultaneous use of multiple taps.
The findings reveal that the time required for water temperature equalization can extend up to one and a half minutes, a delay that could frustrate users expecting immediate hot water. To combat this issue, the study suggests several potential solutions, including the organization of hot and cold water consumption based on priority levels at different intake points, the implementation of buffer heat tanks, and the use of heat generators capable of extensive power regulation with minimized thermal inertia.
This research not only sheds light on the technical challenges of gas heaters but also has profound implications for the energy sector. By improving the efficiency of hot water systems, businesses can reduce their energy consumption and, subsequently, their environmental footprint. As Toropov emphasized, “Improving the energy efficiency of HVAC equipment is crucial for reducing the man-made impact on the environment. Our study provides insights that can lead to more effective solutions in this area.”
The implications for manufacturers are clear: there is a growing demand for systems that can deliver consistent hot water without the discomfort of temperature swings. As energy efficiency becomes a pivotal factor in consumer decision-making, the insights from this research could drive innovation in product design and technology.
This study was published in ‘Vestnik MGSU’ (Bulletin of the Moscow State University of Civil Engineering), reinforcing the importance of academic research in shaping practical applications in the energy sector.
