I found a new-in-box water heater blanket in my basement that the
previous owner apparently left.
What is the thought on using this on a modern heater? Will there be
any measurable benefit?
The result I'd like to see is the water holding its temperature a
little bit longer. We don't use a lot of hot water around my house,
morning showers and a weekly load of dishes usually. I like my showers
almost painfully hot, and even with the new heater, that first shower
of the morning isn't quite up to my standards even on full hot. I
tried raising the temperature, and it helped, but it's borderline
scalding hot now on a freshly heated tank of water. Any higher and
it'll start getting dangerous.
