Villas, duplexes, and self-built houses with large floor areas are often chosen as retirement homes by homeowners. Many HVAC or renovation professionals argue that electric floor heating can be very power-intensive, leading to high electricity consumption. Isn't electric floor heating only suitable for small apartments, and even less suitable for large floor area homes?
Large apartment units are more suitable for electric underfloor heating than small apartment units.
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 weary legs!"
For villa, duplex, mezzanine, and self-built houses 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 examining the 9 common fields of radiant heating selection issues for cognitive breakdown.
2. Insufficient power load?
Villas, split-level homes, and large floor plans have substantial square footage, which necessitates a correspondingly large electrical load. For villas or large floor plans, to accommodate the electrical load of air conditioning and household appliances, a 380V power supply is typically required. However, HOCHTIEF's electric underfloor heating operates on standard 220V household appliance power. 380V refers to a three-phase four-wire system, with three live wires and one neutral wire, each live wire being 220V apart from the neutral. This means that 380V is not just about higher voltage; it is equivalent to having three 220V lines, approximately equivalent to increasing the electrical load capacity.
2. The size of the house and the heated area of the underfloor heating are two different matters.
Even for villas and luxury homes over 1000㎡, at night, it's just one bed in use. With three generations of the family plus a maid, about 5 rooms are sufficient. Even during the sweltering 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, but 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 seldom used, or not used at all, by family members, or in the halls after everyone has retired for the night? It's unnecessary and in reality, it's rarely done that way.
Dr. Deng Tietao, a renowned Chinese physician, emphasizes the importance of cultivating the heart and moral character in health preservation. He advocates for alternating cold and heat, which can promote blood circulation, enhance vitality, and alleviate fatigue. Even in the extremely cold Hulunbeier region of Inner Mongolia, with its roots in the city of Genhe, the houses' good thermal insulation ensures that they do not need to operate at full capacity when unoccupied.
3. Often Overlooked Tuning 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 heating 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 and temperatures achieved over different time frames, with significant discrepancies possible. Achieving uniform heating in each room requires skill, especially for water-based radiant heating, which can be a contentious issue for many users and HVAC businesses. The tuning process often takes a long time, with adjustments needed repeatedly over several days to achieve the desired heating effect. It's not a one-time fix; some systems may require annual tuning.
To reduce the workload during the warranty period and boost profits, HVAC merchants often add equipment like booster pumps, mixing centers, and coupling tanks to increase pressure and balance water pressure. However, this does not solve the problem and actually complicates the radiant heating system, leading to higher installation costs for radiant heating and increased rates of system failures and maintenance costs. Most importantly, these post-warranty costs...
From the above hints, it's important 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 just like air conditioning for summer cooling, it's generally not advisable to run all the underfloor heating in the rooms simultaneously during winter. This often leads to unnecessary麻烦, wasted effort, and a meaningless expenditure of funds, which is truly unnecessary.
4. Rapidly heating radiant floor heating is equivalent to energy conservation.
In non-traditional heating areas 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 it in all rooms. Fast-warming electric underfloor heating offers flexibility in use, which translates to energy savings. For instance, if used for 12 hours a day, the electric underfloor heating would only need to be on for 12 hours. In contrast, a water-based underfloor heating system cannot achieve this; it heats slowly and cannot be easily turned off once activated, essentially needing to remain on.
So, while natural gas water ground heating saves energy per unit price, it ultimately wastes it in speed, thanks to its strength. Calculations show that not only are no savings made, but it might even be more costly. According to a report from Guiyang City, the average annual gas expense for households using gas heating in Guiyang is over 9,500 yuan. Using HOCHTIEF Hohenzollern electric ground heating is far more energy-efficient and cost-effective than natural gas water ground heating.
6. Simple and flexible installation equals safety.
Villas, duplexes, mezzanines, and self-built houses, although spacious, typically have a large number of residents. Therefore, when it comes to the demand for underfloor heating systems, not all rooms necessarily need to be equipped with it. However, with dual-fuel options like natural gas or air-source heat pumps, the initial cost is usually the main unit. Since the main unit has been purchased, it seems wasteful not to install underfloor heating throughout the house, especially when considering a wall-mounted boiler costing over 10,000 yuan can cover areas of 100㎡ or 200㎡. With the larger expenses already incurred, it's natural to proceed with the full-house installation.
Over the past century, HOCHTIEF has set the gold standard for residential and commercial space heating systems with its application development of far-infrared heating technology for baby incubators, allowing the temperature to adapt to you, not the other way around.
Haughti, let the temperature adapt to you
Electricity is a clean energy, also known as renewable energy. With the vigorous development of China's electricity industry, the proportion of renewable electricity such as hydropower, nuclear power, solar photovoltaic, wind power, and biomass power is increasing. The reform of the power system is advancing step by step, and electricity prices will align with the world, becoming increasingly lower. Using electric heating for floor heating with carbon fiber replaces the existing centralized heating, which is conducive to achieving the goal of energy conservation and emission reduction. At the same time, the rapidly evolving electric heating technology has proven to be reliable in terms of safety, stability, and energy efficiency.

Before installing the carbon fiber electric underfloor heating system, the insulation resistance and rated resistance of the electric underfloor heating 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 the system operates normally after being concealed. The concealed sections should be documented with on-site concealed work drawings to facilitate the user's understanding of the carbon fiber electric underfloor heating product layout and prevent damage to the system's structure layers due to house repairs.

Electric Underfloor Heating Usage Instructions:
1. After the ground heating installation is complete, gradually increase the temperature 24 hours later. Ensure the ground is clean and dry before heating to prevent cracking and warping of the flooring due to rapid temperature rise.
2. When using radiant heating for the first time or after a long period of non-use, set the temperature low initially and then gradually increase it, about 1℃ per hour is recommended, allowing the wooden floor to gradually acclimate to the temperature rise. Rapid heating may cause the wooden floor to heat up too quickly, leading to instability, warping, and cracking, which can affect the lifespan of the wooden floor.
3. Avoid fixed decorations or placing furniture without legs on geothermal heated wooden floors to prevent poor heat conduction in localized areas. This can trap heat in the wooden floor, leading to uneven heating and potential warping of the floorboards.

How to Use Electric Floor Heating:
1. Indoor temperatures should be maintained within a reasonable range (16℃ to 20℃ is recommended). Setting the temperature too high not only consumes a large amount of energy but also results in excessive differences between indoor and outdoor temperatures, making it uncomfortable to be indoors and more susceptible to catching a cold.
2. In regions requiring heating, such as northern areas, it is advised not to frequently turn on and off the electric underfloor heating system. The temperature in the room takes time to rise, and frequent on-off operations not only affect the system's lifespan but also the heating efficiency. Additionally, it usually takes about two to three hours to raise the temperature, during which the electricity consumption is relatively high. Frequent on-off is not energy-saving.
3. Preferably use intelligent control systems, which automatically adjust room temperature based on time changes and the occupants' habits to achieve energy-saving effects. For instance, during the evening when users typically are not in the living room, the intelligent control system will slightly lower the temperature there; during the day, when users spend less time in the bedroom, the system will also lower the bedroom temperature accordingly.
