![]() ![]() This is a battery powered device that constantly monitors the functionality of the mat / cable during installation. We provide, free of charge with all mat & cable purchases, a device called the Mat Sense Pro. Altering the length of the wire will change the resistance in the wire and ruin the system. The wire in the mat, or the Nuheat cable may never be cut to change its size. Can I cut the wire to change the mat size / cable length? However, it is just fine to use a 240 volt mat for a small project should you want or need to (for instance, many old electric baseboard heaters are 240v, if you wish to replace this with a Nuheat system, it make sense to reuse the existing 240v circuit in the room). Hence the main difference between the two is that 240 volt is generally used for larger projects (above 150 square feet) and 120 volts for smaller projects. The net result is that a 240 volt control can control twice the square footage of a 120 volt control. When the voltage is doubled from 120 volts to 240 volts, the amperage is cut in half. ![]() The most important thing to know here is that there is no difference in the heat output or energy efficiency between 120V & 240V. What is the difference between 120 volt and 240 volt? Extra lead wire (up to 12 additional feet for a total of 22 feet) may be purchased for $6 per linear feet – please call to place order for extra lead wire mats. Since there is no right or wrong side to a Nuheat mat, the mat may be flipped or turned so that the lead wire is in the most convenient spot to your thermostat. The lead wires are located in a corner of the mat. Where are the lead wires on a Nuheat mat? Please call for consultation on larger projects requiring multiple thermostats or relays – volume discounts may be available. If the sum is greater than 15 amps, a relay contactor or additional thermostat must be used. When using multiple mats or cables, simply add up their amps and if the total is less than 15, a single thermostat will suffice. In terms of square footage, the controls can handle a maximum of 150 square feet of heated floor at 120 volts or 300 square feet of heated floor at 240 volts. Each control can handle a total load of 15 amps (each mat or cable has an amp rating in its description). The question is not how many mats or cables, rather how many amps. Yes, a single thermostat (both 120v and 240v) can control multiple mats, multiple cables, or a combination of mats and cables. Can I control more than one mat or one cable system with a single control? You may use a Nuheat cable system (click here for Nuheat Cable installation instructions). You may order a custom mat (click here for custom mat ordering instructions) or 2. When a room has curves or angles, one of two things can be done: 1. However, they are only available in squares and rectangles. The Nuheat mats are easier and quicker to install. Which product should I use – Nuheat Mats or Nuheat Cable? ![]()
