My small Shop/garage,has tubes in the concrete floor to heat it with. Been there about 8 years. The liquid is heated by an 18 gallon electric water heater. It has worked well for these 8 years and is still heating today. But, yesterday afternoon, I began hearing a buzzing noise coming from that corner of the garage. I checked and found it was coming from the water heater. It was actually vibrating. I turned it off when I quit last night, and when I turned it back on this morning, it was vibrating again. It appears to be the lower heating element that is doing it. Any ideas about what is causing the buzzing?
