Villas, split-level homes, and self-built houses, among large floor plans, are often preferred as retirement homes by homeowners. Many HVAC or renovation professionals argue that electric underfloor heating can be very power-intensive, thus quite energy-consuming. Is electric underfloor heating only suitable for small homes, and even less appropriate for large floor plans?
Large户型residences are more suitable for electric underfloor heating than small户型residences.
Actually, it's just a lack of understanding or misinterpretation of the electric underfloor heating system, or even... merely a subjective judgment based on ego! It truly is the case that spreading rumors is easy, but refuting them is a marathon!
Heating systems for large residential types such as villas, split-level homes, high-rise apartments, and self-built houses are actually more suitable for electric underfloor heating than smaller residential units.
Let's summarize and analyze by dissecting the common 9-domain concerns in choosing underfloor heating systems.
2. Not enough power load?
Villas, split-level, and large floor plans have larger area sizes, and the corresponding electrical load is also greater. For villas or large floor plans, to match the electrical load of air conditioning and household appliances, they typically have a 380V power supply. However, HOCHTIEF's electric underfloor heating uses 220V, which is standard for household appliances. 380V refers to a three-phase four-wire system, with three live wires and one neutral wire, where each live wire to the neutral wire is 220V. This means that 380V is not just a higher voltage but is equivalent to having three 220V lines, approximately equal to an increased electrical load for functional purposes.
2. The size of the house and the heated area of the underfloor heating are two different matters.
Even for villas and mansion over 1000㎡, the family only uses one bed for resting at night. With three generations and a nanny, they only need about 5 rooms. Even during the extreme heat of summer, not many families would turn on all the air conditioners in every room. This isn't just about the cost; it's about whether such extravagance is necessary.
Why run the underfloor heating system at full capacity during the winter, especially in rooms that are rarely used or empty, or in the living room after everyone has gone to bed? It's unnecessary and actually very seldom done.
Traditional Chinese medicine practitioner Deng Tietao emphasizes the importance of nurturing the heart and moral character in health preservation, advocating for the alternation of cold and hot temperatures to promote blood circulation, boost vitality, and alleviate fatigue. Even in the extremely cold Hulun Buir, Inner Mongolia, with its well-insulated housing structures, it is still not necessary to operate at full capacity when the house is unoccupied.
3. Overlooked Debugging and Follow-Up Maintenance Issues
Water-based underfloor heating is not the same as electric underfloor heating. Each room in HOCHTIEF's electric underfloor heating system is independent, with no neighborly relationships or mutual influence. In contrast, water-based underfloor heating is interconnected, which results in different levels of resistance, flow rates, and temperature increases depending on the floor level, area size, and proximity. The time it takes to reach a certain temperature also varies significantly. Achieving uniformity in each room requires real skill, and one can only hope for a dedicated, responsible, and masterful installer. This is often a contentious issue among water-based underfloor heating users and heating and ventilation merchants. The tuning process usually takes a long time, and it's not uncommon to need multiple adjustments, sometimes even annual ones, to achieve satisfactory heating effects.
HVAC suppliers often add equipment like pumps, mixing centers, and coupling tanks to increase pressure and balance water pressure 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. It not only raises the installation cost of the ground heating system but also increases the failure rate and maintenance costs of the ground heating equipment system. More importantly, these post-warranty costs are substantial...
From the above hints, it is crucial to realize that only the simple is reliable, stable, and cost-effective. In life, often 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 not advisable to simultaneously activate underfloor heating in all rooms. This leads to unnecessary hassle, wasted effort, and meaningless expenditure of funds – truly not necessary.
4. Rapidly heating radiant floor heating is equivalent to using energy-saving
In non-traditional heating zones in the 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. With the fast-heating electric underfloor heating, its flexibility in use translates to energy savings, for instance, if it's used for 12 hours a day, the electric underfloor heating only needs to be on for 12 hours. In contrast, the water-based underfloor heating system cannot achieve this; it heats slowly and cannot be easily turned off once it's on, almost requiring constant operation.
So, while natural gas water ground heating saves energy per unit price, it all gets wasted in speed due to its capabilities. When you crunch the numbers, not only are no savings made, it might even end up costing more. 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 electric ground heating is significantly 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, though spacious, typically house a large number of residents. Therefore, when it comes to the demand for radiant heating systems, not all rooms necessarily require it. However, with dual-fuel options like natural gas or air-source heat pumps, the costlier component is often the main unit. Since the main unit has been purchased, and excluding the bathroom, it seems wasteful not to install radiant heating throughout the house. For instance, a wall-mounted boiler costing over 10,000 yuan can cover areas of 100㎡ or 200㎡. With the significant costs already incurred, it's natural to opt for full-house radiant heating.

How to Use Electric Underfloor Heating:
1. Indoor temperatures should be maintained within a reasonable range (16℃ to 20℃ is ideal). Setting the indoor temperature too high not only consumes a large amount of energy but also creates a significant temperature difference between indoors and outdoors, making the space uncomfortable and more susceptible to catching a cold.
2. In areas requiring heating, such as northern regions, it is recommended not to frequently turn the electric underfloor heating system on and off. As the indoor temperature takes time to rise, doing so not only affects the system's lifespan but also the heating efficiency. Additionally, it takes approximately two to three hours to raise the temperature once, during which the energy consumption is significant. Frequent on-and-off usage is not energy-saving.
3. Opt for intelligent control systems whenever possible. These systems automatically adjust room temperatures based on time changes and the occupants' habits, achieving energy-saving effects. For instance, since users typically aren't in the living room at night, the intelligent control system will lower the temperature slightly. Similarly, during the day when users spend less time in the bedroom, the system will also lower the temperature accordingly.

The electric floor heating market is entering a mature development phase. Floor heating companies are growing increasingly mature and robust, and the market is gradually shaping into a sophisticated 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.

Installation Standards for Electric Floor Heating
The installation process for electric underfloor heating is similar to that of low-temperature water underfloor heating. After the ground part of the electric underfloor heating is installed, only a thermostat needs to be mounted on the indoor wall. For the low-temperature water underfloor heating, the ground part installation also requires a boiler and a manifold.
Electric underfloor heating is also safe to use; it has been tested with 4000V high voltage. Household voltage is only about 220V, and the heating element has double-layer protection. Moreover, it features electromagnetic wave shielding grounding protection. In case of any leakage, the main power supply in your home will immediately shut off. The product lifespan exceeds 50 years, and electric underfloor heating has large-scale engineering cases in buildings across China and around the world.
The decorative layer above the electric underfloor heating can be chosen from: tiles, marble, engineered hardwood flooring, solid hardwood flooring (self-regulating heating cables can be used for solid hardwood flooring).
