Hot Water Scald Prevention

We are experts in the field of scald prevention. Do you have a young family? If so you must read this!

Tempering valves can save a burn injury. Here is a quick extract from our code on hot water…

AS 1056.1
With reference to clause 3.2.2 the thermostat for a storage water heater shall be set at not less than 60°C. This clause then explains that a minimum setting of 60°C is specified on the advice of the Department of Health, NSW, that bacteria Legionella pneumophillia do not survive in temperatures above 55°C.

AS 3500.4
With reference to Clause 1.10.2, Part B, all new hot water system installations shall deliver hot water not exceeding 50°C in residential buildings, at the outlet of all sanitary fixtures used primarily for personal hygiene purposes.

Here are the facts:…

• at 50°C, a deep scald takes 5 minutes in an adult or child;
• at 54°C, a deep scald takes 35 second in an adult and 10 seconds for a child;
• at 60°C, a deep scald takes 6 second for an adult and 1 second for a child;
• at 65°C, 2 seconds for an adult and 0.5 seconds for a child;
• at 70°C, in a typical factory setting – 1 second for an adult.

*A tempering valve has on average a 5yr lifespan and cannot be serviced. We recommend replacement after 5 yrs. This valve is a safety valve and cannot be serviced. If the valve fails to operate on your hot water system it is to be replaced.
