My water heater has been on 110F for many years with no complaints.

Mabe there is some heat loss due to the cold?

I am an hour away from this house.

I haven't even had my coffee yet this morning.

Luckily I have a Rheem wifi water heater and I just raised the temp using my phone and now I will go back to my coffee!

P.S. There is no such thing as a hot water heater. They do not heat hot water, they heat cold water to make hot water. They are water heaters. 

A contractor corrected me one time. I still catch myself saying it wrong occasionally and now I notice when people say it wrong.
