Lower your bills by setting the temperature on your water heater at a level sufficient for your congregation's needs. The most common temperature is between 110 and 120 degrees, which is about midway between the low and medium setting. This is an effective temperature range that saves energy and prevents scalding. Generally, reducing water temperature by 10 degrees Fahrenheit will save 3-5% on water heating costs.
As a faith leader, you can help inspire your congregation to care for God's creation.
