The Secret For Choosing The Best Temperature For Your Hot Water Heater

The Best Temperature For Your Hot Water Heater
There is nothing complicated in a technological sense about setting your water heater temperature; just turn the dial, which on most heaters is in plain view or behind an easily removed panel. However, how do you know what temperature to set it at? There is no one right answer to that question, as such factors as safety, energy consumption and health should be considered, and that varies from person to person. The plumbing code states that all water heaters are to be set at 120 degrees to pass inspection. Others may go by widely varied rules of thumb, but at Fast Response Plumbing, we stick with the plumbing code. Here are the secrets and reasonings others use when trying to decide which temperature is best for your hot water heater:

Safety

One thing you want to avoid is setting the temperature so high that people can burn themselves. Most water heaters have a maximum high temperature of 150 degrees Fahrenheit, so obviously that is the setting most likely to cause scalding. However, water just twenty-five degrees lower than that will require several minutes to reach scalding temperature, giving you plenty of opportunity to adjust the faucet to avoid getting burned. The issue of setting too high temperatures is an especially important consideration for households with small children or those who have disabilities making it hard for them to move.

Energy

Setting hot water heaters at lower temperatures results in lower heating bills. The general guide is a four percent saving on power for every ten degree reduction in temperature. However, always remember that reductions should be made only in conjunction with concerns over safety and health. Saving money isn’t everything.

Health

Hot water kills bacteria and germs that can cause disease. Therefore, setting your water temperature too low can result in health risks. For example, Legionella bacteria, which causes Legionaire’s disease, will thrive in temperatures below 120 degrees, but it is killed instantly by temperatures around 140 degrees. For this reason, choosing a temperature much below 120 degrees to save money would be foolishly compromising your health just to save money.

The Ideal

Combining these essential factors of safety, energy consumption, and health, we can see that the ideal temperature range for hot water heaters is between 120 and 140 degrees. Since there is a fluctuation in temperature between the water heater and the tap, you should test your water temperature with a thermometer and keep adjusting the water heater temperature accordingly. Whether you set it at the high or low end of that 120-140 degree range depends on whether you have children, elderly or disabled people in your household and their personal preferences.

Disclaimer “The plumbing code states that all water heaters are to be set at 120, it will not pass inspection if it is set higher than that.”
