Far Infrared Floor Price Hotline

The heating speed of the heating seat is significantly faster than that of the heating cable, and the difference in heating efficiency between the two is due to the fundamental differences in technical principles, structural design, and application scenarios. The following analysis will be conducted from three dimensions: core mechanisms, typical data, and exceptions:   The core mechanism determines the speed difference 1. Heating seat: instant surface heating Direct contact heat transfer: The heating element (carbon fiber, graphene, or metal heating wire) of the heating mat is directly attached to the human body or contact surface (such as mattress, floor), and the heat acts directly on the target area through conduction and radiation. For example, after the carbon fiber heating mat is electrified, the lattice vibration of carbon atoms generates heat, and the efficiency of converting electrical energy into thermal energy is as high as 98%. Moreover, the proportion of far-infrared radiation can reach more than 70%, which can quickly increase the perceived temperature.   Low thermal inertia design: The thickness of the heating mat is usually only 0.5-3mm, and there is no need to heat heavy concrete layers or floor structures, resulting in extremely low thermal inertia. For example, the ultra-thin floor mat of Huanrui Electric Heating can reach the ground temperature within 20-30 minutes after starting, and some high-end products even claim to accumulate heat in 3 minutes and reach insulation state in 15 minutes. 2. Heating cable: System level energy storage heating Indirect conduction and heat storage: The heating cable needs to be buried in a concrete filling layer of 35mm or more. The heat needs to be heated around the cable first, and then slowly conducted upwards through ground materials such as tiles and wooden floors. This process involves multiple thermal resistances, resulting in delayed heating. Thermal inertia and heat storage effect: The concrete layer has a large heat capacity, and during the heating process, it needs to absorb a large amount of heat (about 200-300 kJ/m ³), and the cooling rate is also slow.   Speed comparison in typical scenarios 1. Laboratory measured data Heating seat: Carbon fiber heating mat: After being powered on for 10 minutes, the surface temperature can reach 45 ℃, with an average heating rate of 2.7 ℃/minute; Graphene heating seat: It can raise the surface temperature to 25-30 ℃ within 15-30 minutes, and local areas (such as seats) can feel warmth within 10 minutes. Heating cable: Conventional wet installation: It takes 1.5-2 hours for a 100 square meter residential building to raise the surface temperature from 15 ℃ to 22 ℃, and the temperature only rises by 3-5 ℃ within the first hour; Dry installation (without concrete layer): Heating cables using aluminum plate thermal conductivity modules can shorten the heating time to 30-60 minutes, but still rely on the thermal conductivity of the ground material. 2. Actual application scenarios Heating seat: Local heating: After the heating pad is powered on, it can reach 35 ℃ in 5-10 minutes, which is suitable for quickly increasing the temperature of the human contact area; Temporary use: A portable heating mat used in outdoor tents that can raise the internal temperature to 15 ℃ within 30 minutes in an environment of -10 ℃. Heating cable: Whole house heating: A 120 square meter residential building uses wet heating cable underfloor heating, which requires continuous operation for more than 2 hours to uniformly raise the room temperature to 20 ℃. Additionally, the concrete layer needs to absorb a large amount of heat during the first start-up, and it may take 4 hours to reach a comfortable temperature; Industrial application: Heating cables for antifreeze of oil pipelines require 1.5 hours to maintain pipeline temperature above 5 ℃ in an environment of -20 ℃.   Decision recommendations and scenario adaptation Priority should be given to scenes with heated seats: Requirement characteristics: temporary heating, local heating, rapid response (such as maternal and child care, office nap time). Recommended solution: Heating seat: supports APP remote control, reaching 45 ℃ within 15 minutes; Silicone heating pad: waterproof and pressure resistant, quickly heats up in 3 minutes, suitable for use under laptops. Scenarios where heating cables are preferred: Requirement characteristics: whole house heating, long-term stable operation, and need to have the same lifespan as the building (such as new residential and commercial areas). Recommended solution: Heating cable system: with the help of intelligent temperature controllers to achieve temperature control in different rooms, it can reach 22 ℃ in 2 hours during wet installation, and the overall cost per square meter is relatively low; Dry graphene underfloor heating: suitable for apartments with limited floor height, heating up to 25 ℃ within 30 minutes with a fast heating rate.   Summarize The difference in heating speed between the heating seat and the heating cable is essentially the difference between instant surface heating and system level energy storage heating: The heating mat, with its advantages of direct contact and low thermal inertia, can meet local heating needs within 15-30 minutes, especially suitable for short-term use or speed sensitive scenarios; The heating cable needs to heat the concrete layer and ground structure, and under normal installation conditions, the heating time takes 1-2 hours. However, its stability and long-term energy efficiency are more suitable for whole house heating. Therefore, heating mats are the preferred choice for pursuing fast heating, while heating cables are more suitable for long-term stable heating.
