Villas, duplexes, and self-built houses, among other large-area floor plans, are often preferred for retirement by homeowners. Many HVAC or renovation professionals argue that electric radiant heating can impose a high electrical power load, leading to significant electricity consumption. Isn't electric radiant heating only suitable for small floor plans, and even less suitable 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 radiant heating system, or even... it's merely a subjective judgment based on one's own assumptions! Truly, it's like the saying goes: "Spreading rumors takes one mouth, but dispelling them takes a broken leg!"
For large apartment types such as villas, duplexes, mezzanines, and self-built houses, heating systems are actually more suitable for electric floor heating than for smaller residential units.
Let's summarize and analyze by exploring the common dilemmas in choosing radiant heating systems from nine major fields.
2. Not enough power load?
Villas, duplexes, and large floor plans have expansive areas, which correspondingly require a larger electrical load capacity. For villas or large floor plans, to accommodate the electrical load of air conditioning and household appliances, they typically have a 380V power supply. However, HOCHTIEF's electric underfloor heating uses standard 220V household appliance power. 380V is not just about higher voltage; it consists of three live wires and one neutral wire, each live wire being 220V apart from the neutral. This means that 380V is essentially equivalent to three 220V lines, approximately equivalent to an increased electrical load capacity for functionality.
2. The size of the house and the area heated by underfloor heating are two different matters.
Even for villas and luxury homes over 1000㎡, the whole family, including three generations and a nanny, only uses about five rooms for rest at night. Even during the peak summer heat, it's rare to see many families turn on the air conditioning in all rooms. This isn't just about the cost; it's more 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 mind and virtue in health preservation. He advocates for alternating temperatures, which can promote blood circulation, boost vitality, alleviate fatigue, and more. Even in the very cold Hulunbeier city of Genhe, Inner Mongolia, in China, due to the good thermal insulation of the building structure, it is still unnecessary to operate at full load when there is no one present.
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 comfort heating system is independent, with no neighborly relationships or mutual influence. Water-based underfloor heating, on the other hand, is interconnected, which leads to different resistance in the water system across different floors, areas, and distances, resulting in varying flow rates and temperatures. The time it takes to reach the desired temperature also differs significantly. The distinction can be quite substantial. It's only through installation and adjustment that this can be achieved, and while radiators are somewhat easier, getting each room in water-based underfloor heating to be perfectly tuned requires some real skill. This often hinges on the installer's dedication, professionalism, responsibility, and craftsmanship – a common issue among water-based underfloor heating users and HVAC merchants. The tuning process often takes a long time, with adjustments needed the next day if the heating effect isn't satisfactory, and then again the day after that. This may require multiple tunings, as it's not always a one-time fix, and some systems may even need annual adjustments.
While HVAC suppliers often add equipment such as 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, the problem is not resolved. Moreover, it complicates the radiant heating system, leading to increased installation costs for the ground heating system and higher rates of equipment system failures and maintenance costs. Most importantly, these post-warranty costs are substantial...
From the above hints, it's important to recognize 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're similar to using air conditioning for summer cooling. Generally, all room floor heating systems are turned on simultaneously, leading to unnecessary麻烦, 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 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 once turned on, it's not easily turned off, essentially needing to remain on.
So, while natural gas water ground heating saves energy per unit price, it all ends up being wasted in speed due to its capabilities. Upon careful calculation, 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 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, jump floors, and self-built houses, although with large living spaces, usually have a significant number of permanent residents. Therefore, when it comes to the demand for underfloor heating systems, it's not necessary to install them in every room. However, with dual-fuel options like natural gas or air-source heat pumps, the initial cost is usually the main unit, which has already been purchased. Without installing full-house underfloor heating in the bathroom, it would seem wasteful. For instance, a wall-mounted boiler costing over 10,000 yuan can cover areas of 100㎡ or 200㎡. Since the larger expenses have already been incurred, it's natural to proceed with the full-house installation.
Over the past century, HOCHTIEF has established the gold standard for residential and commercial space heating systems through the development of far-infrared heating technology based on incubator warming panels for newborns, adapting temperature to you, not the other way around.

The electric radiant heating market has entered a mature development phase. With the continuous growth and maturity of heating companies, the heating market has gradually formed a well-structured, scaled-up landscape. The rise of this heating method has added comfort, warmth, environmental friendliness, and fashion to residential homes, gaining societal recognition.

Installation Standards for Electric Radiant Heating
The installation process for electric underfloor heating is similar to low-temperature water underfloor heating. After the installation of the electric underfloor heating ground part, just install a thermostat on the indoor wall. For the low-temperature water underfloor heating ground part, a boiler and a manifold are also required.
Electric underfloor heating is also safe to use; it has been tested under 4000V high voltage. The residential voltage is only about 220V, with double-layer protection for the heating element. Additionally, it features electromagnetic wave shielding and grounding protection. In the unlikely event of a leakage, the main power supply in your home will be immediately disconnected. The product lifespan exceeds 50 years, and electric underfloor heating has been used in large-scale building projects in China and around the world.
The decorative layer above the electric underfloor heating can be chosen from: tiles, marble, engineered wood flooring, solid wood flooring (self-regulating heating cables can be used for solid wood flooring).

Installation procedure for electric underfloor heating:
Before installing electric ground-source heating, test the nominal resistance and insulation resistance of the heating cable.
2. Insulating materials laid on the ground can include heating cable insulation boards. If the ground humidity is high, apply a waterproof membrane first, followed by the insulating material.
3. Laying a layer of reflective aluminum foil over the insulation material can reflect heat.
4. A layer of metal mesh is laid over the reflective aluminum foil layer, with the purpose of preventing the heat cable from being pressed into the insulating material during installation and enhancing the ground's compressive strength.
5. Begin with the power terminal and uniformly lay the heating cable heating section on the metal mesh according to the pre-designed layout of the thermal cable. Tie it every 250mm to prevent crossing or overlapping. Subsequently, cover and encase the heating cable with concrete (thickness approximately 20mm-30mm), and then lay tiles or other ground finishes.
