To figure out if additional insulation will do anything, just put your hand on the insulation when the water is hot. If the insulation is hot, you're losing heat and more insulation will help. If the insulation is cool, additional insulation will make no difference.

You might look into upgrading to a 10 gallon water heater...

I was wondering the same thing?
Our Rockwood 2304KS water heater does not recover nearly as quickly as our previous Dutchman Kodiak hybrid did. And I am hoping there's a way to improve that ?

Your water heater is already in conditioned air and not outside in the cold. You have already lost with 3 females taking showers. I doubt if you could change anything with their habits

You might try to add a Hott Rod element to make recovery faster.....

In our case it's only the wife and I. We take relatively quick showers, and still run out of hot water before finishing.
In spite of the stirofome insulation surrounding the tank I can still feel a lot of heat radiating from the tank and, like the gentleman that started this thread, I am wondering if more insulting can ba added to retain some of this heat loss ?

Great discussion - thanks for all the ideas!

I had never considered using a longer city water hose to help temper the incoming cold water like electroblast suggested - simple, cheap and an easy fix / mod!

Also RamblerGuy, thanks for the suggestion about checking the heat loss through the boiler by checking the temperature of its insulation. As soon as I get the w/h going, its the first thing I'll do.

I was thinking a while ago about installing the hott rod but I found myself wondering if there would be any detrimental effect on my hot water heater by replacing the large sacrificial anode with the hott rod element. Turbs & Fonzie - you have any experience with this?

Again, great suggestions! It's the reason why I joined this forum in the first place!
