Can you get Legionnaires Disease from hot water heater?
Legionella is an aquatic bacteria that thrives in warm water environments and is the cause of Legionnaires Disease. It is commonly found in hot water heaters, potable water supplies, hot tubs, cooling towers, fountains, swimming pools, etc. and multiplies in conditions especially between 68 – 122 °F.

Do tankless water heaters grow bacteria?
Some tankless water heater manufacturers and others have made claims that storage tanks cause Legionella bacteria but that tankless water heaters do not. Most electric or gas tankless water heaters only raise the water temperature to a usage temp between 100 F to 105 F.
What temp kills Legionnaires?
At 140 degrees, Legionella die within about 30 minutes; at 130 degrees, it can take as long as 6 to 8 hours to kill the bacteria; at 120 degrees ─ the recommended temperature for conserving energy ─ Legionella will survive but won’t multiply. Temperatures below 120 degrees encourage the bacteria’s growth.
What temperature should water be to prevent Legionella?
60 °C
Notes. Hot water should be stored at 60 °C at least in order to kill legionella bacteria. The thermometer pocket at the top of the cylinder and on the return leg, if fitted, is a useful point for accurate temperature measurement. If installed, these measurements could be carried out by a building management system .
How do you fix hot water heater bacteria?
You can do that in one of two ways. Up the thermostat setting as you chlorinate, or while the chlorine is going into the water heater you place a UV-C sanitizer light on the water supply. They cost in the upper $400 range and will kill 99.9 percent of the bacteria that passes it.

Can Pontiac fever turn into Legionnaires disease?
Legionella bacteria can cause a serious type of pneumonia (lung infection) called Legionnaires’ disease. Legionella bacteria can also cause a less serious illness called Pontiac fever.
Can hot tubs cause Legionnaires disease?
Hot tubs have been associated with Legionnaires’ disease outbreaks. All hot tubs—including display models—should be operated with proper disinfectant residuals and pH. Public hot tubs should use automatic feed and control systems for disinfectant and pH.
How common is Legionella in hot tubs?
Legionnaires’ Disease in Hot Tubs
This fall, 128 people fell ill after exposure to a hot tub vendor display at the North Carolina Mountain State Fair. Each year between 8,000 and 18,000 people contract Legionnaires’ Disease, a severe and often deadly form of pneumonia caused by Legionella pneumophila bacteria.

How do you prevent Legionnaires in a hot tub?
Make sure disinfectants in hot tubs/spas (like chlorine) are kept at the level and pH needed to reduce the risk of spreading germs like Legionella. If you have symptoms of Legionnaires’ disease or Pontiac fever, such as cough, shortness of breath, fever, or muscle aches, see your healthcare provider right away.
Does chlorine prevent Legionella?
