Temperature
The current building code restricts the maximum temperature for residential use to 120 degrees fahrenheit. Higher settings can result in wasted energy dollars and increase the danger of injury from scalding. Hot water will take longer to arrive at sinks, tubs and showers that are further from the hot water heater.
No Hot Water
If you discover that you have no hot water, check the ignition system, temperature setting and water supply valve before calling for service. Refer to the manufacturer’s literature for specific locations of these items and for other troubleshooting information.
