Villas, split-level homes, and self-built houses, among large-area floor plans, are often chosen as retirement homes by owners. Many HVAC and renovation professionals argue that electric ground heating systems can be heavily power-intensive, leading to high electricity consumption. Is electric ground heating only suitable for small units, and even less appropriate for large-area floor plans?
Large户型residences are more suitable for electric underfloor heating than small户型residences.
Actually, this can only be attributed to a lack of understanding or misunderstanding of the electric floor heating system, or even... mere subjective judgments based on egotism! Truly, it's a case of "a lie told with one mouth, and the truth chased with broken legs!"
For villa, duplex, mezzanine, and self-built homes with large floor areas, the heating system is actually more suitable for electric underfloor heating than for small residential units.
Let's summarize and analyze by addressing the common concerns from the 9 major fields of underfloor heating selection.
2. Not enough power load?
Villas, split-level, and large floor plans have larger sizes, which also require a larger electrical load capacity. For villas or large floor plans, to accommodate the electrical load for air conditioning and household appliances, most have a 380V power supply. However, HOCHTIEF's electric underfloor heating uses standard 220V household appliance power. 380V refers to a three-phase four-wire system with three live wires and one neutral wire, with each live wire to the neutral wire being 220V. This means that 380V is not just about higher voltage; it is equivalent to having three 220V lines, roughly equivalent to increasing the electrical load capacity for functionality.
2. The size of the house and the usable area for radiant heating are two different matters.
Even for villas and luxury homes over 1000㎡, the family of three generations, including the babysitter, only uses about 5 rooms for rest at night. Even during the peak summer heat, it's not common for many families to turn on air conditioning in all rooms. This is not just about the cost; it's more about whether such extravagance is necessary.
Why run the underfloor heating system at full capacity during winter, especially in rooms that are rarely used or empty, such as when family members are scarce or in the evenings after rest? It's unnecessary and actually very rarely done.
Dr. Deng Tietao, a renowned Chinese physician, emphasizes the importance of nurturing the heart and moral character in health preservation. He advocates for the alternation of hot and cold to promote blood circulation, boost vitality, and alleviate fatigue. Even in the extremely cold Hulunbeier Genhe City of Inner Mongolia in our country, the houses have good thermal insulation, so they do not need to operate at full load when unoccupied.
3. Overlooked Debugging and Post-Maintenance Repair Issues
Water-based radiant heating is not the same as electric radiant heating. Each room in HOCHTIEF's electric radiant heating comfort system is independent, with no neighborhood relationships or mutual influence. Water-based radiant heating, on the other hand, is interconnected, leading to different system resistances, flow rates, and heating times depending on the floor, area, and distance. The temperature achieved and the time required to reach it can vary greatly. It can only be achieved through installation and adjustment. While radiators are easier, getting each room in water-based radiant heating to be perfectly identical requires real skill. This is often left to the hope of encountering a dedicated, responsible, and masterful water-based radiant heating installer, which is a common issue for many water-based radiant heating users and HVAC businesses. The adjustment process often takes a long time, with the heating effect being checked the next day, adjusted if it's not satisfactory, and then checked again the day after that, potentially requiring multiple adjustments. It's not always a one-time adjustment, and some may need to be adjusted annually.
HVAC suppliers often add boosters, mixing centers, and coupling tanks to increase pressure and balance water pressure, in an effort to reduce the workload during the warranty period and boost profits. However, this does not solve the problem and makes the radiant heating system more complex. Consequently, it not only raises the installation costs for radiant heating but also increases the system's failure rate and maintenance costs. More importantly, these post-warranty costs are substantial...
By the above hints, it is important to recognize that simplicity is the key to reliability, stability, and cost-effectiveness. In life, many times, convenience is more important than saving money.
Villas, duplexes, and self-built houses may have large floor areas, but when it comes to winter heating, just like using air conditioning for summer cooling, it's generally unnecessary to turn on all the underfloor heating in all rooms simultaneously. This leads to unnecessary麻烦, wasted effort, and meaningless expenses, which are truly not needed.
4. Rapidly heating radiant floor heating is equivalent to using energy-saving
In non-traditional heating zones in southern regions of our country, we do not require a continuous operation of the underfloor heating system during winter, nor do we need to activate the system in all rooms. With electric underfloor heating, which heats up quickly, its flexibility in use translates to energy savings. For instance, if we use it for 12 hours a day, we only need to run the electric underfloor heating for 12 hours. In contrast, a hydronic heating system cannot achieve this; it heats slowly and cannot be easily turned off once it's on, requiring almost constant operation.
So, while natural gas water floor heating saves energy on a per-unit basis, it's all wasted in speed due to its strength. Calculating carefully, not only is there no savings, it might even be more costly. According to a report from Guiyang City, the average annual gas heating cost for households using gas heating in Guiyang is over 9,500 yuan. Using HOCHTIEF's electric floor heating is much more energy-efficient and cost-effective than natural gas water floor heating.
6. Simple and flexible installation equals safety.
Villas, townhouses, split-level homes, and self-built houses, though spacious, often have a large number of residents. Therefore, when it comes to the demand for radiant heating systems, it's not necessary to install underfloor heating in every room. However, with dual fuel options like natural gas or air-source heating, the initial high cost is usually for the main unit. Since the main unit has been purchased, and excluding the bathroom, it seems wasteful not to install full-house radiant heating. For instance, a wall-mounted boiler costing over 10,000 yuan can cover 100㎡ or 200㎡ areas. With the larger costs already incurred, it's natural to opt for full-house installation.
Over the past century, HOCHTIEF has set the gold standard for residential and commercial space heating systems through the development of far-infrared heating technology for baby incubators, making the temperature adapt to you, not the other way around.

Prior to installing the carbon fiber electric floor heating system, the insulation resistance and nominal resistance of the electric floor heating products should be tested. To prevent accidental damage to the insulation layer of the electric floor heating products during installation, a retest should be conducted before installing the carbon fiber electric floor heating products to ensure the system operates normally after being concealed. The concealed areas should be sketched on-site as a concealed work drawing to facilitate the user's understanding of the carbon fiber electric floor heating product layout and avoid damaging the system's structure layers during house repairs.

The principle of carbon fiber electric floor heating:
The principle of operation is that under the stimulation of electricity, carbon molecular clusters generate "Brownian motion," resulting in heat energy through the collision and friction between carbon molecules, producing a large amount of infrared radiation. The conversion rate of electrical energy to heat energy exceeds 98%.
The main component of the "temperature control system" is the electric heating thermostat. The thermostat controls the heat provided by the carbon fiber electric floor heating by sensing changes in the indoor environment temperature. Setting a reasonable heating temperature can significantly enhance the system's efficiency and reduce energy consumption.

Installation of electric underfloor heating:
Inspect the laying area to confirm it meets the construction requirements.
b. Clear the laying area.
c. Install insulation layer (only on the bottom layer)
d. Install reflective layer
e. Install steel mesh.
f. Lay out heating cables according to the design drawings.
g. Test the standard resistance and insulation resistance of the heating cable.
h. Lay the cement mortar thermal storage layer according to design requirements, act as a moisture-proof isolation layer, lay the floor decorative materials, and complete the ground construction.
Install the thermostat.
