Hot water coming into the house is low?

50gal electric hot water heater. Only a few years old. No leaks.

Set for 130 but when it comes into the house at the closest point to the heater it only registers 105 on a thermometer!

Novice here could use some ideas what might be causing this. Thanks

Have you tried just setting the thermostat higher. I had a Bradford White several yrs ago with an inaccurate stat.

Does the line into the house need to be insulated; is it losing that much heat along the way?

It's called temperature drop. The temp will drop if the pipe runs through an outside wall.

Thanks everyone.

The thermostat nay goes to 140 and I have it set at 130.

I measured the incoming temp at the closest points it enters the house and at that point after runnng it long enough where it should have been hot, it measured 105.

We had this WH put I n about 18 months ago and that’s about when these heating problems started.

We are only a family of three. The front bathroom is the closest point from the WH. The person that uses it is fine. Our bathroom is completely on the other side of the house and by the time we take two more showers the water is barely Luke warm and sometimes cold!

It’s a 50 gal tank.

Have you checked the setting on both thermostats. You should have an upper and a lower thermostat and they will both need to be adjusted.

I don't know why your water heater would be outside anyway. It's just common sense that the further away the water heater is from bathrooms the more heat loss will occur along the way. Running out of hot water after 3 successive showers isn't unusual even with a 50 gallon electric water heater. Most likely your last water heater had a thermostat that could be set much higher than 140 and was set as high as 150 or 160.
