Periodically inspect your dryer vent to ensure it is not blocked. This will save energy and may prevent a fire. Manufacturers recommend using rigid venting material – not plastic vents that may collapse and cause blockages.
If your home's water heater feels warm, consider insulating it to save 7 to 16 percent annually on water heating costs. Insulation blankets are available for as little as $20. Make sure to follow the manufacturer’s recommendations.
