Adding extra insulation to hot water heater???

Is there any benefit to adding extra insulation around the hot water heater and possibly insulating the hot water lines that you can access? I have a Suburban SW6D (propane only) and with three females that like their morning showers hot, my w/h is often times playing catch up. I realize the heater can only heat x gallons of cold water per hour but I was hoping some additional insulation would help retain some heat and I figure that every little bit helps. Anyone try this already or is it a waste of time?

I seriously doubt you would notice any difference. Retaining heat isn't your problem, it's the small tank and recovery time causing your issue. Only solution is to adjust showering schedule and/or habits.

I hear you but the recovery time was one of the reasons I thought the additional insulation would help - albeit a small improvement. You're right, we're staggering the shower times now to give the w/h a chance to recover. Just looking for ways to improve the situation.

they have a pretty thick layer of styrofoam, which is a very good insulator.

Are you putting on electric AND gas heat? That helps recovery time.

Unfortunately you'd only better your situation by getting a gas / electric model.

With that being said Hott rod makes a kit to add a electric element.

The OP stated propane only water heater.


OP, Teach them how to adjust just enough hot water to get flow. Then turn on the cold and adjust to temperature. After wetting down, shut off the shower head slide valve while they soap up. Finally, turn the shower head valve back on and rinse. Done.
The kids that ignore the instruction simply take their shower last. This is what works for us. My wife is usually last.
In other words, I believe there would be no benefit.

I never try that isolating my tank , but what I do it use 50' or longer water hose from City water tap to the TT, at least the water is getting in the TT is at outside temperature instead of been at underground cold temperature, since the water is warmer that helped me getting the recovery time shorter for Hot water.

In Nashville last year it was so hot that you really didn't need the wh as the water coming in was HOT!
