Electric water heater is only 3 years old, so I called the company that sold and installed the unit to report the problem.
Service guy shows up and believes that the bottom heating element in the hot water heater is not working and he will be back later to replace it. He also mentions that water is flowing out of the hot water heater. So?
A different service guy shows up with the replacement heating elements. Since they have to replace the lower element, they might as well replace the upper element while they are at it.
Service guy is unable to proceed because he does not have a socket wrench large enough to remove the heating element and he will be back later with a larger socket wrench. He also mentions that water is flowing out of the hot water heater. So?
A third service guy shows up with the largest socket wrench and replaces the heating elements. One element has some calcium deposits on it, but otherwise the old elements tested out OK with his ohmmeter! He also mentions that water is flowing out of the hot water heater. So?
Still no hot water, so I call again and the head service guy said he would send a service guy out to replace the thermostats in the water heater.
A fourth service guy shows up and immediately notices that water is flowing out of the hot water heater, which indicates there is a leak. The hot water heater is fine, but just can't keep up with the water flowing out and thus, the lack of hot water throughout the house.
As a result, the hot water heater is constantly running, which causes the water pump to constantly run in order to provide cold water to the hot water heater. Which results in an electric bill that is three times the normal monthly electric bill! (I had been going round and round for two months trying to figure out why my electric bill had tripled and now I finally had a solution.)
The service guy determines that the leak is in the hot water line to the kitchen sink. The line runs under the house, which is built on a slab. After 30 years, the house's settling probably broke the pipe. After considering all the options, he plans to run a new hot water line through the ceiling to the kitchen sink.
I await his arrival Monday morning as I type this.
Needless to say, all my femulating the past few days has been in my head.
