SunTouch has made a lot of improvements to what was already fantastic cable system with their new WarmWire 3.0 cables—and without increasing the cost!
A quick glance at the differneces between WarmWire, Nuheat Cable, and the Ditra Heat Cable systems.
Nuheat is the easiest way to get a heated floor, since the mats are pre-built for you!
Nuheat™ offers 120 standard size pre-built square & rectangular floor heating mats that are ready to fit your room and will keep almost any flooring at a warm and comfortable temperature that you set on the thermostat control. All Nuheat mats are less than 1/8” thin and are available in 120V or 240V (aka 110V or 220V), and you can install 150 square feet of 120V mats per control, or 300 square feet of 240V. Warm tiles can be yours overnight with the Nuheat under floor heating system.
People often ask us if they should be using cork insulation for their heated concrete flooring. We tell them that many contractors & homeowners recommend that you insulate between an existing concrete slab & your new Electric Radiant Floor Heating System. Insulation is not required, but many customers like to install a "thermal break" while they are installing new floor heating over a slab subfloor. Heat transfers to cold material, meaning warm objects or surfaces transfer heat to cold ones. An Insulating material on top of the slab and under the Electric Radiant Floor Heat elements will slow the transfer of heat from the heating elements into the bottom of the slab and effectively decrease the time it takes your floor warming system to warm the part your floor that matters.
No. Both systems have the same efficiency and produce the same amount of power: 12 watts per square foot. The only difference is that 240 volt mats pull half the amperage (current) of 120 volt models, which means a single thermostat can control up to 300 sq ft of 240 volt heating elements while 120 volt systems are limited to 150 sq ft. The only instance in which 240 volt is recommended for rooms smaller than 150 sq ft is when there is already an available 240 volt circuit in the room.
