I'm pretty sure I know the answer, but does putting insulation around the outside of a water heater have large effect on its efficiency? I would think it would, depending on how much insulation was used. But the blankets that they make for water heaters are expensive and not very thick. What if I just took some R-13 attic insulation and wrapped it around the water heater? Any ideas on how well this would work and if it would be worth it?
