Manufacturer’s brand name incised

The hot and cold wire joint of the heating cable is the key part of the electric heating system. The Halmburger is processed by the German patented technology by means of cold processing technology.
The 2.2 meters cold wire can be lengthened and cut. For example, if the cold wire is extended, the copper conducting wire cross-sectional area should not be less than 2.5mm2 (recommend use of RV multi-strand cable).

Made in Germany

No. 1 heating cable sales in Europe
Established in 1959, Halmburger is Germany’s largest supplier of intelligent electric heating systems, its professional quality technology and products are in both Germany and the Europe.

High Efficiency

The Aluminum foil composite shielding layer improves thermal conductivity by acting as insulator against magnetic and radio frequency emission associated with electrical cables, thus reduces waiting time of floor heating.

Reduce Humidity Level

Solution to the spring humid climate – When room temperature increases by 1 °c, the relative humidity level drops by 4-5%. It can further prevent the growth of mold, bacteria, and improve skin and respiratory allergies.

Reduce Humidity Level

Solution to the spring humid climate – When room temperature increases by 1 °c, the relative humidity level drops by 4-5%. It can further prevent the growth of mold, bacteria, and improve skin and respiratory allergies.

Test result

  • The floor heating system is the solution to the high air humidity during rainy seasons around Spring and Summer. When the room temperature increases by 1 °c, the relative humidity level drops by 4-5%.
  • This can also prevent the growth of mildew and mold and improves skin and respiratory allergies.
  • Furthermore, moisture will be heated up through the floor to balance the overall space humidity. This avoid cold and humid air from sinking to the ground.
