How long is recovery from ambient? Until I retired and was home all day, I turned mine off until two hours before I returned, and ditto for wake up. Couple extra insulation batts and it wouod stay around 100f

It took about 2 hours after filling the water heater with cold water to heat up to the stock setting of 120 F.
The instructions on this water heater specifically say not to add additional insulation to the outside of the water heater. I suspect they are concerned that people will cover the intake and exhaust vent. It also has a pretty thick stock Styrofoam jacket. The top insulation is about 3 inches thick.
