Underfloor Heating Cable - Specifications
Klima Underfloor Heating Cable
The Klima Cable underfloor heating system is a 7mm twin conductor resistance cable, which is not only economical to run but simple to install. The system is for use in new build projects such as an extension or conservatory where it is embedded into a sand/cement screed on an insulated base. By insulating the base, optimum energy efficiency is achieved.
The Klima Underfloor Heating Cable system has an option of a manual thermostat control or a sophisticated digital control both operated via a floor sensor giving effective, flexible control. It is a complete heating system, which can be used as primary or comfort heating. By using the spacer strips or wire grid the wattage output per square meter can be adjusted to suit individual requirements. The minimum thickness of screed required excluding tiles is 30mm onto a concrete slab, if going directly onto a foil backed insulation board the minimum thickness of screed required is 65mm.
A twin conductor cable custom made by Alcatel with a capacity of 17 watts/m at 230 volts with
2 x 2m contact cable The welded connection between the contact and the resistance cable is marked < SPLICE >. The contact cable 2m length is marked with ******** and may be lengthened if required.
The under floor heating cable is patented world wide and is produced to conform to IEC 800 regulations (ISO 9001) and is CE marked. It is accepted by European approved institutes.
TECHNICAL DETAILS
Type Capacity Amp Ohm Linear length Contact cable
Set 500W - 30 linear meters - 2.1 Amps
Set 1000w - 59 linear metres - 4.3 Amps
Set 1700w - 100 linear metres - 7.4 Amps
Calculations for Heat Requirements
150 Watts/m_ for normal heating cable spacing 100mm
100 Watts/m_ for comfort heating of normal rooms cable spacing 150mm
125 Watts/m_ spacing 125mm
DO NOT SPACE AT MORE THAN 150mm APART Heating will not be effective!
The above figures are approximate. Heat loss calculations should be carried out to estimate the heat requirement. Insulation, roof height, and area to be covered can affect the heat requirement. To obtain optimum energy efficiency it is essential that sufficient insulation is used in the base. Failure to do so may result in heat loss and impaired performance. Check compatibility of insulation with electric underfloor heating.
