What is the maximum temperature allowed for residential water heaters in Massachusetts?

In Massachusetts, the maximum temperature allowed for residential water heaters is established to enhance safety and efficiency. The correct answer indicates that the maximum temperature is 210 degrees Fahrenheit.

This temperature limit is set to prevent scalding and to ensure that the plumbing system operates within safe parameters. Water temperatures above this threshold can pose significant risks, particularly in households with young children or elderly individuals, who may be more susceptible to burns. Additionally, maintaining a lower maximum temperature helps in reducing the risk of overheating, which can lead to pressure relief valve failures and potential system damage.

Furthermore, while water heaters can function at higher temperatures, safety standards prioritize preventing injuries and ensuring that plumbing systems are not subjected to unnecessarily high-temperature conditions that could compromise their integrity over time.

In contrast, the other temperature options fall below or exceed the established safety guidelines. Therefore, 210 degrees Fahrenheit strikes the right balance between effectively delivering hot water and maintaining safety standards.
