I just bought and installed a new Whirlpool Energy Smart water heater.
It's been running for a couple weeks now, and I notice that it feels
cool to the touch, while the 20-yr-old water heater felt warm (both
inside and outside the insulating blanket).
Do today's new "Energy Smart" water heaters need a blanket?
Thanks a heap,
Need? No. Can they help? CERTAINLY!
We just got a new water heater, and it's more efficient than the
15-plus-year-old one it replaced, and the blanket is on. More
insulation is better than less . . . .

I bought one too a month ago and asked the guy in the plumbing department if
a blanket is required. He said no. Makes sense if the heater feels cold to
the touch so you not loosing heat (except on the top of the unit) so what
would a blanket buy you?
Actually, if it feels Warm to the touch it would be losing heat. If
something is insulated very well it will feel the same as it's
environment when you touch it.
If it's 70 in your house, your water heater should feel cool to the
touch... mine does.
New hearters have excellent insulation and will feel like room temp.
A heater blanket properly installed cant hurt, but the energy saved may
nver cover the cost of the blanket purchase:(
Plus the heat lost helps heat your home, in a small way, so only in non
heat times of year would the blanket really save anything assuming your
tank is in a otherwise heated space.
My own questions about the newer water heaters and a blanket were
answered like this.
Tripple paned windows save more energy than double paned windows.
However, the energy savings over their life, doesn't exceed the cost
of triple paned windows. So keep your money, and spend it elsewhere.
Now that wasn't a yes or no, but made me rely on the manufacturer's
instructions for help. Also a quick G-search for "water heater
blanket debate" can yield some results.
