Water temperature testing for legionella.

Hot water storage cylinders calorifiers should store water at 60 c or higher hot water should be distributed at. Below 20 c and the hot water is hot above 50 c. Water temperature thermometer for legionella monitoring control legionella control internationals range of professional water temperature thermometers and legionella testing kits have been carefully selected to help those with responsibility for the routine monitoring and control of legionella bacteria in water systems. The water management program team should regularly monitor water quality parameters such as disinfectant and temperature levels.

Controlling legionella using water temperature thermal control legionella bacteria thrives in temperatures between 20 c and 45 c. When state regulations or codes do not allow hot water temperatures above the range of 105 f 120 f 40 6 c 49 c for hospitals or 95 f 110 f 35 c 43 3 c for nursing care facilities or when buildings cannot be retrofitted for. By monitoring these parameters the team can ensure that building water systems are operating in a way to minimize hazardous conditions that could encourage legionella and other waterborne pathogens to grow. This is why the hse s guidance recommends keeping hot water above 50 c 55 c in healthcare and cold water below 20 c.

Hot water should be stored at 60 c at least in order to kill legionella bacteria. Because of this and because of the risks of legionella exposure it s vital that water systems are regularly tested for the bacteria. Water services should be operated at temperatures that prevent legionella growth. If the water used in a building by accident or design sits between 20 45 degrees celsius legionella and other potentially dangerous bacteria can breed and spread through the water system.

The thermometer pocket at the top of the cylinder and on the return leg if fitted is a useful point for accurate. That s why regular temperature.
