Villas, split-level homes, and self-built houses, among other large floor plans, are often chosen as retirement homes by homeowners. Many HVAC or renovation professionals argue that electric underfloor heating can be highly power-intensive, leading to significant electricity consumption. Isn't electric underfloor heating only suitable for small apartments, and even less suitable for large floor plans?
Large户型residences are more suitable for electric underfloor heating than small户型residences.
Actually, this can only be due to a lack of understanding or misunderstanding of the electric floor heating system, or even... it's just a self-righteous subjective judgment! Truly, it's said that a lie gets halfway around the world before the truth has a chance to put its shoes on!
For large-area housing types such as villas, duplexes, split-levels, and self-built houses, heating systems are actually more suitable for electric underfloor heating than for smaller residential units.
Let's summarize and analyze by identifying the common 9 areas of concerns when choosing underfloor heating.
2. Not enough power load?
Villas, split-level homes, and large-area户型offer substantial floor space, necessitating a corresponding high electrical load. Most villas and large-area户型are equipped with 380V power supply for the electrical load of air conditioners and home appliances. HOCHTIEF's electric underfloor heating system, however, utilizes 220V standard household power. The 380V system, which is a three-phase four-wire configuration with three live wires and one neutral wire, each carrying 220V, means that it's not just a higher voltage; it's effectively equivalent to three 220V lines, approximately equal to an increased electrical load capacity for functional use.
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 square meters, the family of three generations, including the babysitter, typically only uses about five rooms for rest at night. Even during the height of summer with extreme temperatures, it's not common to see many families running air conditioning in all rooms; this isn't just about costs, but whether it's necessary to be so extravagant.
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 expert Deng Tietao emphasizes the importance of nurturing the heart and virtue 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 Genhe City of Inner Mongolia, China, due to the good thermal insulation properties of the building structure, the house does not need to operate at full capacity when unoccupied.
3. Overlooked Debugging and Post-Maintenance 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, heating times, and temperatures achieved, which can vary significantly. It's only through installation and adjustment that this can be achieved; radiators are somewhat easier, but to fine-tune each room in water-based radiant heating to be identical requires real skill. This often hinges on encountering a dedicated, professional, responsible, and craft-minded installer, which is a common issue among many water-based radiant heating users and HVAC merchants. The adjustment process often takes a long time, with the need to adjust and re-evaluate the heating effect over several days, sometimes requiring multiple adjustments. It's not always a one-time fix, and some systems may need annual adjustments.
While HVAC merchants 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, the issue is not resolved. Instead, it makes the radiant heating system more complex, resulting in not only increased installation costs for the radiant heating but also higher failure rates and maintenance costs for the heating equipment system. Most importantly, these later costs occur outside the warranty period...
By the above hints, it's important to recognize that simplicity is 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 just like using air conditioning for summer cooling, it's generally unnecessary to simultaneously activate underfloor heating in all rooms during winter. This leads to unnecessary trouble, time-consuming efforts, and a wasteful expenditure of money that is truly not needed.
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 electric underfloor heating, which heats up quickly, the flexibility in usage 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, a hydronic 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 floor heating saves energy per unit price, it all ends up being wasted in speed, thanks to its prowess. Upon closer calculation, not only are no savings made, it might even end up being more costly. According to a report from Guiyang City, the average annual gas bill for households using gas heating in Guiyang is over 9,500 yuan. Using HOCHTIEF Hochtief electric floor heating is significantly more energy-efficient and cost-effective than natural gas water floor heating.
6. Simple and flexible installation equals safety.
Villas, duplexes, mezzanines, and self-built houses, despite their large living space, often have a high 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 high cost initially lies with the main unit. Since the main unit has been purchased, it seems wasteful not to install underfloor heating throughout the house. For instance, a wall-mounted boiler costing over 10,000 yuan can cover areas of 100㎡ or 200㎡. With the larger costs already incurred, it's natural to proceed with full-house underfloor heating.
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 for baby incubators, making temperature adapt to you, not the other way around.

Electrical radiant heating installation precautions:
Before installing electric underfloor heating, ensure the power lines and meter capacity can support the system's electrical load. For those that are insufficient, apply for an increase in electrical capacity first to meet the system's power requirements.
2. For newly constructed or newly renovated residential properties, after the system is installed and the ground decoration is completed, it is necessary to wait for the ground to naturally dry (approximately 28 days) before heating. During ground decoration, be mindful to avoid damaging the heating cable to prevent system damage.
3. Strictly prohibit the use of joists as subflooring for flooring installation to prevent nails from piercing the ground and damaging cables, which could lead to electric leakage.
4. Choose home furnishings with a base that is at least 4 inches off the ground to ensure heat dissipation and prevent damage to furniture from underfloor heating.
5. Upon initial system startup, the initial heating rate is slower, typically requiring at least 3 hours, and up to 12 hours if the ground heat storage layer is thick. Additionally, there is a structural heat storage process, which usually lasts for about a week; during this time, do not lower the heating temperature or shut down the system.
6. When heating, turn the thermostat switch to the "on" position, then adjust the ground temperature and room temperature. Initially, set the temperature to a lower level (3℃ above the base temperature), wait for the heating cable to operate for a while, and then gradually increase the temperature.
7. When away for an extended period, do not shut off the systems in rooms with plumbing, such as bathrooms and kitchens. Set the room temperature around 5°C to prevent pipes from freezing and cracking.

Electricity is a clean and renewable energy source. With the vigorous development of China's electricity industry, the proportion of renewable electricity sources 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. The use of electric heating in place of existing centralized heating with carbon fiber ground heating 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.

The electric ground heating market is entering a mature development phase. Ground heating companies are growing increasingly mature and robust, and the ground heating market is gradually shaping into a well-developed and scaled-up situation. The rise of this heating method has added comfort, warmth, environmental friendliness, and fashion to residential spaces, gaining social recognition.

Electrical Underfloor Heating Usage Instructions:
1. After the installation of the underfloor heating is completed, gradually increase the temperature 24 hours later. Ensure the floor is clean and dry before heating up to prevent cracking or warping due to rapid temperature rise.
2. When using the underfloor heating for the first time or after a long period of non-use, set it to a low temperature first, then gradually increase the heat at a rate of about 1℃ per hour. This allows the wooden flooring to gradually acclimate to the temperature rise. Rapid heating may cause the flooring to expand and distort, leading to cracking and reducing its lifespan.
3. Avoid installing fixed decorations or placing furniture without legs on the wooden flooring of ground-source heating systems to prevent poor heat distribution in localized areas and to avoid trapping heat in the flooring, which can lead to uneven heating and potential warping of the wood.
