Maximum Temperature of a Solar Water Heater
Based on the data from the monitoring and logging project, the highest temperature ever recorded is 100.31 on the afternoon of 28-07-2024.

Solar water heaters are systems capable of delivering extremely high water temperatures, especially during the summer months when sunlight is intense and consistent. The maximum temperature that water can reach in a solar water heater depends on several factors, such as the type of collectors, sun exposure, and weather conditions.
Often, modern solar water heaters can heat water to temperatures ranging from 60°C to 90°C. In extreme cases, where sunlight conditions are exceptionally favorable, water can reach up to 100°C, especially if the system lacks sufficient consumption and water remains in the collectors for long periods. This can lead to overheating, which most solar water heaters prevent with built-in overheating protection systems.
To avoid unpleasant situations, such as burns or damage to the system, most solar water heaters are equipped with safety valves and mechanisms that regulate the pressure and temperature of the water, such as a thermostatic valve. There is also often a thermostat that allows control over the maximum temperature the water can reach, ensuring system safety and efficiency.
