Best Temperature for Hot Water Tanks
Professional plumbers in Edmonton are of the opinion that the temperature of your hot water tanks should be adjusted according to the task for which the hot water is going to be used.
In order to prevent the risk of pathogens, it is important for you to set the temperature of hot water tanks properly. The temperatures of water that affect the survival of pathogens growing inside the stored water in the tanks are as follows:
- Above 70o C – Pathogens die instantly
- At 60o C – 90% pathogens die in 2 minutes
- At 50O C – 90% pathogens die in 1-2 hours
- At 48 – 50o C – pathogens survive but do not multiply
- At 32 – 42o C – the pathogens start to grow
If you set the temperature too high, it might scald the user. Young children and older people are at great risk as their skin is thinner as compared to the others. They will also not be able to move away quickly from the scalding water. The professional plumbers in Edmonton recommend the temperature to be set at 49o C.
The recent dishwasher models need minimum 49o C. Most of the new dishwasher models come with heaters and have the capability of heating the interiors. If you own an older dishwasher, you should check out the specifications for adjusting the best temperature for hot water tanks.
