Hot water systems must supply water at temperatures hot enough to meet cleaning demands but not so hot as to risk injury to people. Children, the disabled, and the elderly are most susceptible to hot water-related injuries. Currently, the maximum temperature criteria calls for temperatures to be in the 120-125ºF range. As part of this companies service to out customers, we check the temperatures of the water system and advise our customers accordingly.
The risk of scalding or other injury from hot water can be estimated by the exposure time v/s the water temperature. The table below indicates the risk of injury to a normal healthy person. Keep in mind that these times are reduced for children, the disabled, and the elderly.
- 120ºF - More than 5 Minutes
- 125ºF - 1-1/2 to 2 Minutes
- 130ºF - About 30 Seconds
- 135ºF - About 10 Seconds
- 140ºF - Less than 5 Seconds
- 145ºF - Less than 3 Seconds
- 150ºF - About 1-1/2 Seconds
- 155ºF - About 1 Second
If your water temperature is in excess of 125ºF, consider adjusting your thermostat accordingly. While individual comfort levels and reaction times vary, according to the water heater manufacturing association, the maximum recommended bathing water is approximately 104ºF.

That is great information and the temp of water is probably something we all take for granted, especially if we do have good feeling and are able to react to water that is too hot...
I really like that gadget and it is a useful tool, since I bet most of us couldn't tell the temp with just our finger
Thanks for the photo post.
