Ovens Never use your oven to heat your home. This misuse of your oven puts you at risk of burns from hot surfaces and shortens the life of oven parts and controls. Water Heaters Make sure your water heater is anchored to a wall. This will help prevent the heater from shifting and possibly falling in an earthquake. A temperature of 120 degrees F. will help avoid scalds.
Some dishwashers require a higher temperature.
Furnaces Your furnace should be serviced once a year to help maximize its life and performance. Follow the instructions in the owner's manual, or call a heating or plumbing contractor. Have your furnace checked for fire hazards such as a damaged firebox and any dislodged, clogged or rusted vents. Clean or replace your filter after each month of heavy usage. Replace the blower door cover after checking your filter.
