Is your water heater too hot, too cold, or just right?
Your water heater is one of the most important components of your plumbing system, and ensuring it's set to the right temperature will help you stay safe and manage your energy costs.
Use a temperature gauge to set your water heater temperature between 60ºC (140ºF) and 65ºC (147ºF). The minimum temperature is needed to prevent the growth of bacteria. The top-end temperature recommendation is helpful to reduce the risk of scalding and to manage your electricity bill.
Scalding is even better prevented by setting the temperature at faucets and showerheads to a maximum temperature of 49°C. You can do this by installing a mixing valve before the fixture outlet.
If the factory setting on your water heater was set too high, consider adjusting it. You can save 5% on your electricity bill by reducing your electric hot water heater temperature by 6°C, which equates to up to $21 in savings per year.
