Hello, I'm am from the Netherlands and new here on this forum.
Last week I bought a EMF-390 and succesfully located a cell tower near my bedroom. I tackeld the problem by making cutains with Swiss Shield. Great!
But here's my question: I have extreme EF readings at SOME of the radiators in my house. How can this be possible? The EMF-390 display says STATIC.
Thanks,
Michiel |

| It's mostly accumulated charges around the radiators. |

Yes it is, but not with all radiators. So it is not in the whole system I presume.
With the two or three radiators that have this problem the EMF-390 goes stuck at the end of the EF-scale. |

Maybe try grounding your radiators.Strange that they are floating.
Are they independent night storage or water ?
Use a multi meter with long leads to measure the resistive difference between the radiators that are highly charged with those that are not.
Ground everything.Especially the Swiss Shield.That helps to defeat RF.
In NL I use the silver and polystyrene underfloor insulation material
to block RF.Works well doubled over. |

| Thanks Paul, it's water. The EF reading is not floating. It is steady with each radiator. But while one radiator has max EF, the another one next room has a low reading. All the radiators are connected with the central heater with metal pipes. There's no wiring in the wall near the radiators and I have a natural broadloom carpet on all floors. That's why I still don't understand these extreme differences per radiator. |

| It may be that pipes of some radiators pass close to AC wiring. The active radiators are then acting like antennas. |

No Bill, I wrote: there is no wiring in the walls near the radiators ...
And it's about EF (static) electric fields. Not RF.
Any suggestions? |

| Try cleaning it? and the carpet too? and the Wall? Maybe it had a lot of dust and had accumulated a lot of static charges. |

Sorry ,I don't understand either.
A water central heating system is normally grounded not floating.
So all radiators should be more or less the same,close to 0 Volts.
It should therefore be environmental,like EmfDev suggests.
Windows, just popped into my mind,but that is more an RF problem.
Ghosts ? |

| If it is a static surface charge you should be able to wipe it off. Also, in my experience, the meter does not register much of a static charge unless there is relative motion between the charge and the meter. The faster the motion, the higher the reading as the meter cuts across the electric field lines. I have tried this multiple times with a charged comb. (The same is true of magnetic fields; even a strong magnet will barely register unless it is moving relative to the meter.) |

Dust! I was laughing because of the low-tech caracter of this possibility.
But thanks, I'm going to clean one radiator and look what it will do.
I'll be back here ... |

Unfortunately the dust was not the culprit. But yesterday I suddenly realised I re-painted 3 radiators of the 10 when we moved to our new house 7 years ago.
These are exactly the radiators that give these high EF readings on the EMF-390. Is this a coinsidence or could this be the cause? |

| Is this a metallic paint? I assume they were repainted because the original paint was degraded. Since these radiators are somehow different, could the underlying process that caused the original paint to degrade also cause a charge to build up? Just a thought. |

Yes Bill, the paint was degraded. The paint I used was not metallic, but you never know whats in it.
I think I leave the subject for what it is.
Thanks everyone for letting your brains run for me! |

| Hi, I donīt know why but I do know that central heating generates static electricity. When itīs on, I get electrocuted every time I move. Maybe due to the friction between the moving water and the radiators and pipes. Because I have some sensitive computer systems at home and also do custom pc builds, I always turn off the central heating to prevent static discharges.(my computers generate enough heat anyway) |
