How to choose carbon fiber heating wires and metal heating cables for electric underfloor heating system installation?
The national standard specifications representing the highest authority in the HVAC industry have already made the best choices. Let's take a look together.
Electric floor heating systems, as functional facilities for a modern minimalist lifestyle of comfort, have gradually gained recognition and preference from an increasing number of consumers.
In the era of information explosion in online self-media.False exaggeration in advertising is widespread and has even reached the radiant heating industry. So, when choosing a residential electric ground heating system, should one opt for a metal heating cable or a carbon fiber heating wire?
We discuss the choice between metallic heating cables and carbon fiber heating cables for indoor electric ground heating, using national standards and media opinions. (Feel free to save and bookmark this information, and welcome contacts from all over the country with ground heating needs.)
Currently, the available references for the indoor electric ground heating field in the country can be simply stated as:2Unit
1：JGJ 142Radiation Heating and Cooling Technical Code (General Specification)
2：GB/T 39938 / IEC 62999:2016 In-room Electric Heating, Floor Heating - Performance Features, Definitions, Testing Methods, Dimensions, and Formula Symbols
as well asJGJ 142Standard Technical Code for Single-Line Detailing of Low-Temperature Radiant Heating Systems (Electric Floor Heating) for Radiant Heating and Cooling Technology Procedures
JG/T 538Carbon Fiber Heating Wire for Construction (Industry Standard for Construction Industry)
1 Scope: Applicable for rated voltage of low-temperature radiant heating systems used in industrial and civil buildings300/500VRadiant Heating and Cooling Technology Specification
3.1 Carbon Fiber Heating Wire: A line-type electrical heating element composed of continuous carbon fiber filaments, electrical insulating materials, a protective sheath, and cold and hot connectors, which generates heat upon being energized.
Here we go, an important standard needs to be introduced.
GB/T 20841Rated Voltage300/500VHeating cables for life facility heating and anti-icing
Scope: Suitable for heating cables used in residential facility heating and anti-icing
1.4.1 Heating Cables: Cables capable of dissipating heat, with or without metallic shielding, jacket, or armor, designed for heating purposes.
1.4.2 Heating Conductor: The metallic part of a heating cable that converts electrical energy into heat.
Next, according to Baidu Encyclopedia, carbon fiber heating cables are more energy-efficient compared to similar metal heating cables.20%Above, does not produce harmful electromagnetic radiation waves to humans, achieves the purpose of "use as needed, open as needed, not open when not needed," emits far infrared during winter heating, which is beneficial to human health, and other advantages.
It is not difficult to see from the aforementioned national standard technical specifications.
Carbon fiber heating cables for indoor comfortable heating systems
Select metal heating cables for applications such as heating and frost prevention of living facilities, road and roof de-icing and frost prevention, and pipe heating to prevent freezing.
Based on national standards, there's no room for error. When choosing between an indoor electric floor heating system or outdoor heating and anti-freezing facilities, be sure to understand whether it's a carbon fiber heating element or a metal alloy heating core. Don't use them in the wrong place.
The far-infrared heating method of carbon fiber heating cables is not ideal for deicing applications, and vice versa!
The look is similar, but the uses are quite different.
