The UFH4U heating cables are available in many sizes which allow you to adjust the amount of heat you generate per square meter to your requirements (from 100-200 watts/ m2). They are ideal for use in small or odd shaped areas.
The UFH4U heating cables are easy to install and can be used under tiled floors (up to 200 watts/ m2) by covering the entire cable with a flexible tile adhesive and all other floor finishes by encasing them in 10mm of a flexible levelling compound.
Heating Cable Specifications:
Heating cables come in a Variety of lengths from 9m - 150m
Output 15 watts / m
The heating cable is 2.8 mm and Twin conducting with only 1 connection point
Heating cable comes with heavy duty double sided tape to secure to the sub-floor
There is 3m of power cable extension
The Heating Cable Kits come complete with thermostat and floor sensor probe
The 'black' Heating Cable must NOT be cut under any circumstances
The heating cables can be laid at any wattage (100 -200watts/ m2) according to your needs and the floor finish.
Installation recommendations
If the floor finish is:
1. Tiles / stone:
a. You may use up to 200watts/ m2 beneath tiles / stone
b. The tiles / stone may be laid directly on top of the heating cable however, the entire heating cable must be encased in the flexible tile adhesive.
2. Wood, laminate, carpet, linoleum:
a. We do not recommend you exceed 160watts/ m2 beneath these finishes
b. The heating mats must be encased in 10mm of a flexible levelling compound first.
The tile adhesive / levelling compound act to evenly distribute and transfer the heat and protect the heating cable and floor finish
The tables below show the cable length (and spacing's) required to cover a variety of different room sizes (according to desired wattage).

We recommend you aim to cover between 90-95% of the 'free floor space' of the area you wish to heat to insure good coverage (how to measure up).
The Heating cables will operate far more efficiently when used with insulation board (such as Marmox (link to Insulation Board)). The use of insulation board minimises the transfer of cold up from the subfloor and the loss of heat down in to the subfloor.
Installing the heating cables
The UFH4U heating cables are easy to install. Firstly you make sure the sub floor is clean, dry and secure. Then you can lay the cable out at the required spacing to achieve the wattage required. The cable is stuck to the floor using the included double sided adhesive tape. Next you install the floor probe in a suitable position. Once you connect the thermostat and test that everything is working correctly, you are ready to install the floor finishing.
If you are using ceramic tiles or stone flooring, you cover the heating cable with the flexible tile adhesive and then lay the flooring on top. If you are using wood, laminate, linoleum, carpet etc, you cover the entire heating cable with 10mm of a flexible levelling compound. Once the levelling compound has dried you can install the flooring.
For a more comprehensive guide to installing 'UFH4U' heating mats please see the relevant instruction manuals.
The spacing between the lengths of underfloor heating cable dictates the wattage per square metre you generate.
Any combination of cables can be used to provide the required 90-95% coverage in the area for underfloor heating. Several underfloor heating cables can easily be installed in paralell in to the rear of the thermostat or via an electrical junction box (up to a total of 3,600 watts).
When used beneath a tiled floor, the tiles may be laid directly on top of the heating cable, however the entire cable must be encased in the flexible tile adhesive.
When used beneath any floor finish other than tiles (wood, laminate, vinyl, linoleum or carpet) the heating cable must be encased in 10mm of a flexible self leveling compound before the floor finish can be laid.
If laying the underfloor heating cable at 200watts/m2 and your area is larger than 11m2 you will need to use an additional heating cable to supplement the heating cable kit.
When combinations of heating cables are used they must all be laid at the same wattage/m2.

The underfloor heating cable are used to supplement a underfloor heating cable kit if you have an area larger than that covered by the largest cable (this will depend on the wattage you choose to generate).
