How to Set Water Heater Temperature

What is the Perfect Water Heater Temperature

Most water heaters are set to 140 degrees. This is a good temperature for the reason that the bacteria, legionella, cannot multiply and almost all are not able to survive in such hot conditions. On the other hand, 140 degrees may be too hot for little children and the elderly. If one is seeking to save money too, think about modifying the water temperature to around 120 and 130 degrees. The cost savings is not very significant, but this is the minimum suggested temp to prevent contaminating water with legionella. Although this bacteria is okay to consume, it can be incredibly unsafe when taken into the lungs. Legionella lives and breeds in warm water but not in hot water. However, when thinking about what heat range to set ones water heater to, it is important not to set it too high. Second and 3rd degree burns can happen on adult skin in five seconds with the preset temperature of 140 degrees, so do not set the water temperature any higher and think about setting it lower if there are small kids or elderly people in the home.
