The invention of the water heater added great convenience & luxury to the home, but if the temperature is too high, hot water scalding can occur.
Many homeowner’s are unaware that you can regulate the temperature of the water heater. Some people only turn there water temperature down if on vacation and choose to temper the hot water with cold instead. The safer way is to turn down the temperature of the hot water supply.
Turning down the temperature on your water heater can not only prevent accidental scalding but save you energy costs too. Traditionally, water tanks came pre-set to a temperature of 60°C (140°F). Today, a maximum water temperature of 49°C (120°F) is recommended, however scalding may still occur. Bacteria can also grow in your tank if below 60°C (140°F), so the Canada Safety Council recommends 54°C (130°F) maximum. The Building Code maximum at fixtures is 49°C (120°F), except for dishwashers & clothes washers.
Installing automatic mixing valves on faucets, showers & tubs, or an anti-scald mixing valve on your water heater can also achieve this. This work would typically be carried out by a licensed plumber.
Play it safe! Ensure your water temperature is appropriate for your water heater and safe before you use it.
