187: Insulate your water heater by matthew

Every time you complete this action, you will reduce emissions by an estimated 146 lbs. CO₂e.

Even if replacing your hot water heater is out of financial reach, there are some simple and inexpensive steps you can take to reduce your water heating costs and CO₂ emissions. You can cut the heat loss from your water heater by installing about $15 worth of insulation, and save around 5% on your water heating bills and emissions. As long as you consult an experienced source before beginning the project, this is a safe and inexpensive way to reduce some of your household emissions.

Note: If you’ve just purchased a new water heater, don’t bother insulating it. New models are already insulated, and your D.I.Y. project won’t generate any savings.
