Transformers are the small black or grey cylinders on power poles that take massive amounts of electricity from the lines and reduce it to a safe level for your home. High amounts of EMF are emitted from transmission power lines, also known as high-tension wires, and transformers. The EMF is emitted from both the device and the wire carrying the current to the device. The magnetic field is proportional to the current - which is the amount of electricity. The electric field is proportional to the voltage, which moves electricity through the wires. Before we get to whether or not there's any danger of you getting cancer from your warmed floor, we need to learn a little bit about an EMF.Įvery alternating electric current (AC) creates both magnetic and electric fields. Anything that runs on electricity has an EMF - your microwave oven, clock radio, floor lamp, hair dryer and yes, your radiant floor heating (RFH) system. If that can have ill health effects, then you'd think that the radiant floor system would, too.Ĭoncerns about electric blankets are because of electromagnetic fields (EMF) they emit. But you've probably been told that it's bad for you to sleep under an electric blanket while it's turned on. It's like an electric blanket without the fabric. In this case, the heat warms the floor and, over the course of an hour, the rest of the room. The plastic mat, made of heat-resistant polyethylene, contains looped resistance wire that carries an electrical charge, transferring heat to anything it touches. The concept is simple - when you're building a new bathroom or renovating an existing one, you lay an electric heating mat on the subfloor and tile over it. Some people say that nothing beats the soothing warmth of a tiled bathroom floor heated by an electric radiant heating system.
