Why do I need to use a LoudMouth and a multi meter to check WarmWire during installation?
Although the wire is extremely tough, it can be damaged during installation. The culprit is often another trade, but it can be the sharp edge of a trowel. When you open your WarmWire box, there is a label attached to the power lead that shows the resistance of the wire (each length is different). You need to measure this Ohms value with a digital multimeter before you begin work and when you are finished, and log the readings in your installation manual. During the job, however, you should hook up the LoudMouth which does not give you a resistance value, but does sound an alarm if that value changes suddenly. These two devices work very well together and give you peace of mind during the entire installation. Warm Your Floor offers a low cost Digital multimeter if you do not own one.
