Question: 1 / 400

What can happen if a propane hot water heater is set too high?

It may not heat water efficiently

It could lead to scalding

When a propane hot water heater is set too high, one significant risk is the potential for scalding. Water temperatures above a certain threshold, generally above 140°F (60°C), increase the risk of burns, especially for vulnerable populations such as children and the elderly. By setting the water heater to a lower temperature, typically around 120°F (49°C), the risk of scalding is significantly reduced, allowing for safer use while still maintaining adequate hot water for daily needs.

In this context, while high temperatures can affect efficiency, energy saving, and the lifespan of the heater, the most immediate and critical concern is the safety hazard posed by scalding hot water. Therefore, it is essential to maintain appropriate temperature settings on hot water heaters to ensure the safety of all users.
