The electric field on my pillow reads 55v/m. There is a wired-in heated towel rail the other side of the wall from my head. Would using a demand switch so the electric current is cut off at night significantly reduce this field or do i need to remove the towel rail?
Any advice from the electrically discerning would be gratefully received. |

let me first of all check how you got that reading?
was the reading obtained while you were holding the monitor? (which monitor did you use)
were you isolated from the fields in the floor?
the reason I'm trying to find more information is that my first inclination is that the fields from the rail shouldn't be that high if through a wall..

I got the reading while i was kneeling on the bed, so my feet were off the floor. i got a similar reading while holding the meter and just putting it on the pillow. I used a professional EMF meter.
Does that clarify the problem?
Many thanks for your help. |

It is unlikely to be coming from the towel rail unless it is faulty. All the ones that I have seen are metal clad and have to be earthed, so they give off zero electric fields. The electric fields may be coming from the wiring to the heated towel rail - I assume that there is a fused outlet on the wall close to the towel rail? If so, take the fuse out and re-measure the electric fields - I suspect they will be approximately the same as now.
Electric fields can be particularly difficult to track down and minimise. Commonly they come from the downstairs lighting wiring that induces electric fields in upstairs floors and them up through the bed. These then go back to the nearest best-earthed surface, which may well be the wall with the earthed heater screwed to it.
I would move the bed away from the wall, stand on the floor and measure the fields from the wall about 20 cm away from it. Then stand on a piece of earthed cooking foil (if possible) or a plastic box or a couple of phone-books in a thick plastic bag (if not) and re-measure. If the readings go down, then the source is coming from the floor. Then the bed needs on either have earthed metal pads under each leg, or if it sits flat on the floor, to have an earthed foil sheet placed under it to stop the e-fields couiling into the bed.
