The temperature of water heaters should be no higher than __________.

The recommended maximum temperature for water heaters is 130 degrees Fahrenheit to prevent serious scalding injuries. Water at higher temperatures can cause burns very quickly, especially for vulnerable populations like children and the elderly. At 130 degrees Fahrenheit, the time it takes for serious burns to occur is significantly increased, enhancing safety for users. This temperature is commonly advised by safety organizations to balance the need for hot water with the risk of burns, making it the most appropriate choice in scenarios where safety is a priority.

Higher temperatures, such as 140 or 150 degrees Fahrenheit, significantly decrease the time it takes for burns to occur, leading to greater risk, especially in households with young children or less mobile individuals. Thus, maintaining water heater temperatures at or below 130 degrees Fahrenheit aligns with best practices in home safety and injury prevention.
