It won't be 140 by the time it reaches you, but will steadily increase as you shower. If you have nerve issues, you might not realize it before you are scalded 140 degrees can produce third degree burns in 5 seconds.

It's also dangerous for people that are visiting, and don't realize you have it that high, so warn them. Especially if they have small children. And they are in the guest shower closer to the tank, like in our house.

We took the TECO deal and got the recirculating tankless water heater. The advantage is that because it recirculates, you can set the temp lower (we are at 120) and you still get hot enough water to shower sooner at your most remote point. At 120, it will take over a minute to get a third degree burn.

We still warn our guests, however.
