Eamonn who is engineering adviser for Dept of Environment and has been building inspector for over 30 years needs to educate himself a little more. He says that Legionella is killed within seconds once it goes over 60c which is NOT true . WHO and WRAS recommendations Legionella pneumophila requires on average 3.2 minutes exposure to 60oC to reduce the bacteria count by a factor of 10. That is to say 3.2 mins to reduce from 100,000 to 10,000; a further 3.2
mins for 10,000 to 1,000; and 3.2 mins for 1,000 to 100 cfu/l which would be considered an acceptable level. https://www.wras.co.uk/downloads/public_area/publications/ge...
