I beilieve you will notice quite a difference if you do cover your
water heater. The easiest and least expensive way to do it is simply
use some good wall insulation. Just be sure you get none near the pilot
light. The "blankets" look real pretty but not sure they are worth the
price. Sometimes local electric companies will give you a great deal on
them but not sure about gas. $20 at a home store will buy you more than
enough insulation.

Any reason to put a heater-blanket over the unit ?

I keep hearing that modern water-heaters are sufficiently insulated.
