Posted By Richard Podmore Can anybody tell me how hot should hot water be? Obviously, I know how hot it shouldn't be but is there a maximum or minimum specified somewhere as I can't find it?

Posted By Jez Corfield It really depends on what it is being used for - if you are worried about employees or others burning themselves then be aware that water coming out the tap at as little as 45-50'c could cause burns with some vulnerable people. For staff it may be prudent to warn them of hot water by way of signs, if elderly or very young have access to your water supply it might be worth assessing the risk and possibly fitting thermostatic control of some sort.

Posted By Alan Houghton To prevent Legionairres disease water should be stored at 55 deg C minimum. To minimise scald risk to vulnerable users, hot water should be delivered at 44 deg C max this usually means fitting TMV's (Thermostatic Mixer Valves). Legionella organism can multiply rapidly water temperature between 20 deg C & 40 deg C and the presence of sludge, scale, rust, algae and organic matter to provide nutrient (food). There's a conflict in required conditions most easily resolved by fitting a TMV. Bear in mind that a TMV will cost around £100 + fitting and to maintain the low risk there should be an effective maintainence program. To determine whether or not to fit TMV's we use an individual risk assessment using test questions recommended by Health & Safety Executive/Local Authorities Liason Committee (HELA) in their advice to enforcing authorities.
