hot water heater emfs
Locked
 
|
I have a hot water heater that is in an outside shed but against my
bedroom wall. Even with the fuses switched off, it emits very high magnetic fields (measured on my meter). The elecric doesn't seem to be a problem though. Wondering if anyone has any suggestions - barriers to use, where to get, etc? Thanks Jill |

Just because a meter picks up high magnetic fields doesn't necessarily mean it is bothering you (that is, there is not necessarily a direct correlation between a meter reading and adverse health impacts) Marc |

Hi Jill,
It is very unusual for a device to emit strong magnetic fields if the fuses/breakers are switched off... because a current is required to produce a magnetic field. So, if the fuses/breakers are off, then there must be current flowing somewhere outside the wiring that is downstream of the fuses/breakers. I would try the following with the help of an assistant: Have one person mount your gaussmeter in a fixed position near the heater in question. Have the assistant go to the main circuit box (not fuses/breakers at the heater) and turn off one breaker, then another, and another until all the breakers are off. Somewhere in that sequence, you will notice a dramatic drop (hopefully to zero) in the magnetic fields. Note that breaker number. Now, with that breaker remaining in the off position, turn on the other breakers, one at a time. Does any of the magnetic field return? On which circuits? Now comes the hard part: once you have identified the circuit(s) that are contributing to the high readings, you will need to either: 1] shut those fuses/breakers off when you want to be in the vicinity of the heater, or 2] find out why high current is flowing in THAT circuit. It is obviously not because of the heater. Is there incorrect wiring? Ground current? Some other appliance on that same circuit? Etc. A very good book to help you find and correct wiring problems is Karl Riley's "Tracing EMFs in Building Wiring and Grounding".

Hello,
many, many years ago, when I got my first meter, I found strong magnetic fields on my microwave. I turned it off. But the magnetic fields remained. I then unplugged teh microwave. But the magnetic fields remained. I had to rethink. I then found, that the cable, which led to the wallsocket was a 2-wire cable. So, there was no ground attached to the wall socket. I than replaced the cable with a 3 wire one, and assured myself, that the grounding was in order. Then the magnetic fields were gone. Conclusion; even when the current is off, but no grounding exist, the magnetic AC fields remain in the apparatus. So therefore a good grounding is essential in the house.
