Insulating the hot water pipes in your home can save energy wasted through heat loss, and keep your hot water from cooling before it reaches the tap.
        
    
        - Skill level: Basic to advanced
 
        - You can find easy-to-install, insulating pre-slit pipe covers at most home improvement stores.
 
        
        - Cost range: $20-$40
 
        - Pipe insulation is very inexpensive. Use it to wrap the first 6 feet of pipe coming from your water heater, or extend the insulation throughout your home’s piping system for even more energy savings.
 
        
        - Savings: Reduce standby heat losses by 25%-45%
 
        - Insulating your pipes will further reduce heat loss, and may make the temperature reduction on your water heater’s thermostat even less noticeable.
