Is there any regular servicing that needs to be done on a regular basis for an electric hot water heater? My wife is convinced that our water heater needs something done to it. I haven't noticed any issues, but she says she runs out of hot water when she's taking a shower. (Yes, she likes long showers.)
If there is a regular servicing that needs to be done, what actually is done to the heater?
