Burner operation and recovery rate are fine. It's just that when the tank sits unused for awhile the temp drifts down and the burner doesn't kick on until the water gets way cooler than you want. It's like the bimetal contol is just way to insensitive.
So the first shower in the morning is cool but that gets the burner to start and then the second and third showers are fine. When I come down in the AM I open the hot faucet and run the water off until I hear the whoosh of the burner lighting. Then it heats up while I have breakfast and I get a hot shower.
A couple years ago Sears was selling some models that had self-powered Honeywell digital controls that supposedly had upper and lower temp detectors for better temp control. I don't think they have the same ones now. Lowes has a Whirlpool model with some sort of electronic control. I was wondering if these are a better alternative to the old bi-metal t-stats... or if my bi-metal t-stat is just an outlier and that most work better?
