Villas, townhouses, and self-built houses with large floor areas are often preferred as retirement homes by homeowners. Many HVAC or renovation professionals argue that electric floor heating has a high electrical power load, which naturally consumes a lot of electricity. Is electric floor heating only suitable for small units, and not at all for large floor area houses?
Large apartment units are more suitable for electric underfloor heating than small ones.
Actually, this can only be attributed to a lack of understanding or misunderstanding of the electric floor heating system, or even... it's merely a self-righteous subjective judgment! Truly, it's the case that spreading rumors is easy, but debunking them is a marathon!
For large-area housing types such as villas, duplexes, split-level homes, and self-built houses, heating systems are actually more suitable for electric radiant heating than for smaller residential units.
Let's summarize and analyze, focusing on the common 9 areas of radiant heating selection concerns for in-depth understanding.
2. Insufficient power load?
Villas, split-level, and spacious floor plans have larger area sizes, necessitating a larger power load and corresponding配套设施. For villas or large floor plans, to accommodate the electrical load of air conditioning and household appliances, they typically have 380V power supply. However, HOCHTIEF's electric underfloor heating uses standard 220V household appliance power. 380V, which stands for three-phase four-wire, consists of three live wires and one neutral wire, with each live wire to neutral being 220V. This means that 380V is not just about higher voltage; it is equivalent to having three 220V lines, approximately equivalent to an increased electrical load for functionality.
2. The size of the house and the heated area of the underfloor heating are two different matters.
Even for villas or luxury homes over 1000 square meters, the family only uses one bed for rest at night. With three generations of family members and a保姆, they typically only need about 5 rooms. Even during the peak summer heat, it's not common for many families to turn on all the air conditioners in every room. This isn't just about the cost; it's more about whether it's necessary to be so extravagant.
Why run the radiant heating system at full load during the winter, especially in rooms that are rarely used or empty at night, or in spaces with few family members present? It's unnecessary, and in reality, it's rarely done that way.
Traditional Chinese medicine practitioner Deng Tietao emphasizes the importance of nurturing the heart and virtue in health preservation. He advocates for alternating hot and cold to promote blood circulation, enhance vitality, alleviate fatigue, and more. Even in the extremely cold Hulun Buir, Inner Mongolia, where the city of Genhe is located, due to the good thermal insulation properties of the building structure, it does not require full load operation when unoccupied.
3. Overlooked Debugging and Subsequent Maintenance and 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 neighborly relationships or mutual influence. In contrast, water-based radiant heating is interconnected, leading to varying resistance in the water system across different floors, areas, and distances. This results in different flow rates, temperatures, and the time required to reach the desired temperature, which can vary significantly. Achieving uniform heating in each room requires skill, especially for water-based systems, as it's not as straightforward as with radiators. It often hinges on the dedication and craftsmanship of the installer. This is a common issue among water-based radiant heating users and HVAC businesses. The tuning process can take a long time, with adjustments needed repeatedly over days, sometimes even annually.
HVAC suppliers often add equipment like booster pumps, mixing centers, and coupling tanks to increase pressure and balance water pressure to lighten the workload during the warranty period and boost profits. However, this does not solve the problem and makes the radiant heating system more complex, leading to increased installation costs for the underfloor heating and higher rates of system failures and maintenance costs. More importantly, these are all post-warranty costs...
From the above hints, it's crucial to realize that simple is reliable, stable, and cost-effective. 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, they face the same issue as summer air conditioning: it's generally not advisable to run floor heating in all rooms simultaneously, as it leads to unnecessary hassle, time-consuming expenses, and is simply not necessary.
4. Rapidly heating radiant floor heating is equivalent to using energy-saving
In the southern regions of our country, which are not traditional heating areas, we do not need our electric underfloor heating systems to run continuously throughout the winter, nor do we need to activate the system in every room. The quick-heat electric underfloor heating offers flexibility in use, which translates to energy savings. For instance, if we use the system for 12 hours a day, the electric underfloor heating only needs to be on 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 ground heating saves energy on a per-unit basis, it all ends up being wasted in speed due to its capabilities. When you crunch the numbers, not only are there no savings, it might even end up being more costly. According to a news report from Guiyang, the average annual natural gas heating cost for households using gas heating in Guiyang is over 9,500 yuan. HOCHTIEF electric ground heating is far more energy-efficient and cost-effective than natural gas water ground heating.
6. Easy and flexible installation equals safety.
Villas, duplexes, jump-level units, and self-built houses, although large in size, often have a high number of residents. Therefore, when it comes to the demand for radiant heating systems, not all rooms necessarily need to be equipped with radiant heating. However, with dual fuel options like natural gas or air-source heat pumps, the high cost typically lies with the main unit. Since the main unit has been decided on, it seems wasteful not to install full-house radiant heating, especially considering the expense has already been incurred. For instance, a wall-mounted boiler costing over 10,000 yuan can cover 100㎡ or 200㎡ areas. With the larger costs already paid, it's natural to opt for full-house heating.

Hochtiw, let the temperature adapt to you
Carbon fiber electric floor heating, carbon fiber is a microcrystalline graphite material obtained through carbonization and graphitization treatment of organic fibers. The microstructure of carbon fiber is similar to artificial graphite, featuring a disordered layered graphitic structure.

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," producing heat energy through the collision and friction between carbon molecules, emitting a large amount of infrared radiation, with an electrical to thermal energy conversion rate of over 98%.
The main component of the "temperature control system" is the electric heating thermostat. The thermostat regulates 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.

The electric ground heating market is entering a mature development phase, with ground heating companies growing increasingly sophisticated and robust. The market is gradually shaping into a well-rounded and规模化 landscape. The rise of this heating method has added comfort, warmth, environmental friendliness, and fashion to residential spaces, gaining social recognition.

Prior to installing the carbon fiber electric underfloor heating system, the electrical insulation resistance and rated resistance of the products should be tested. To prevent accidental damage to the insulation layer of the electric underfloor heating products during installation, a retest should be conducted before installing the carbon fiber electric underfloor heating products to ensure normal operation after concealment. A concealed work drawing should be drawn on site to facilitate the user's understanding of the carbon fiber electric underfloor heating product layout, and to avoid damaging the system's structure layer due to house repairs.
