Villas, split-level homes, and self-built houses, among large floor plans, are often chosen as retirement homes by owners. Many HVAC and renovation professionals argue that electric underfloor heating can be quite power-intensive, leading to high electricity consumption. Isn't electric underfloor heating only suitable for small homes, 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... mere subjective judgments based on self-righteousness! Truly, it's a case of "a lie told with one mouth, and the truth pursued with both legs."
For large-area housing types such as villas, duplexes, high-rise apartments, and self-built houses, heating systems are actually more suitable for electric floor heating than for small residential units.
Let's summarize and analyze, focusing on the 9 common fields of floor heating selection issues for cognitive dissection.
2. Not enough power load?
Villas, duplexes, and large floor plans have substantial square footage, which necessitates a correspondingly larger 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 used. However, HOCHTIEF's electric underfloor heating operates on standard 220V household appliance power. 380V, which is a three-phase four-wire system with three live wires and one neutral wire, means each live wire is 220V apart from the neutral. In other words, 380V is not just about higher voltage; it's equivalent to having three 220V lines, roughly equivalent to increasing the electrical load capacity for functionality.
2. The size of the house and the usable area for underfloor heating are two different matters.
Even for villas and luxury homes over 1000㎡, the family only uses one bed for rest at night. With three generations of the family plus a nanny, they typically need around 5 rooms. Even during the peak summer heat, it's rare for many families to turn on all the air conditioners in every room. This isn't just about costs; 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 not used at all when family members are scarce, or in the living room after everyone has gone to bed? It's unnecessary, and in reality, it's rarely used that way.
Traditional Chinese medicine doctor Deng Tietao emphasizes the importance of nurturing the mind and virtue in health preservation. He advocates for alternating hot and cold temperatures, which can promote blood circulation, enhance vitality, and alleviate fatigue. Even in the very cold Hulun Buir of Inner Mongolia, China, the houses' good insulation performance means they do not need to operate at full capacity when unoccupied.
3. Often Overlooked Tuning and Follow-Up Maintenance Issues
Waterfloor heating is not the same as electric floor heating. Each room in HOCHTIEF's electric floor heating comfortable heating system is independent, with no邻里 relationships or interferences. In contrast, waterfloor heating systems are interconnected, which leads to different resistances, flow rates, and heating times depending on the floor, area, and distance. The time required to reach the desired temperature can vary greatly. Achieving uniformity in each room requires genuine skill, and this often depends on encountering a dedicated, diligent, responsible, and artisanal waterfloor heating installer, a common point of contention among many waterfloor heating users and heating merchants. The adjustment process often takes a long time, with the heating effect being assessed the next day, and adjustments being made if needed. This may be repeated several times, and it's not always a one-time adjustment; some systems may need to be adjusted annually.
And HVAC merchants often add equipment such as 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 also makes the radiant heating system more complex. It not only increases the installation cost of the radiant heating system but also raises the failure rate and maintenance costs of the system, and most importantly, these post-warranty costs...
From the above hints, it's crucial to recognize that the simple is reliable, stable, and cost-effective. In life, often convenience is more important than saving money.
Villas, townhouses, and self-built homes may have ample space, but when it comes to winter heating, much like air conditioning for summer cooling, it's generally not advisable to turn on all the floor heating in every room at once. This leads to unnecessary麻烦, wasted effort, and a meaningless expenditure of funds, which is truly not necessary.
4. Rapidly heating radiant floor heating is equivalent to energy conservation.
In non-traditional heating zones in southern regions of our country, we do not require continuous operation of the radiant heating system during winter, nor do we need to activate it in all rooms. Fast-warming electric radiant heating offers flexibility in use, which translates to energy savings. For instance, if used for 12 hours a day, the electric radiant heating system only needs to be on for 12 hours. In contrast, the water-based radiant heating system cannot achieve this; it heats up slowly and cannot be easily turned off once it's on, requiring nearly 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 sheer strength. 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 expense for households using gas heating in Guiyang is over 9,500 yuan. HOCHTIEF's 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, although spacious, often have a large number of permanent 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 based on baby incubator warming trays, allowing the temperature to adapt to you, not the other way around.
Hochtiw, 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 electricity for heating in place of the 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.

Before installing the carbon fiber electric floor heating system, the insulation resistance and nominal resistance of the electric floor heating products should be tested. To prevent accidental damage to the insulation layer of the electric floor heating products during construction, a retest should be conducted before installing the carbon fiber electric floor heating products to ensure the system operates normally after being concealed. The concealed parts should be drawn on-site as a concealed work drawing to facilitate the user's understanding of the installation of the carbon fiber electric floor heating products and to avoid damage to the system's structure layer due to house repairs.

Electric Floor Heating Usage Instructions:
1. After the underfloor heating installation, gradually increase the temperature 24 hours later. Ensure the floor is clean and dry before heating to prevent cracking or warping due to rapid temperature increase.
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 at a rate of about 1℃ per hour. This allows the wooden floor to acclimate to the temperature increase gradually. Rapid heating may cause the wooden floor to expand and distort, leading to cracking and reducing its lifespan.
3. Avoid fixed decorations or placing furniture without legs on geothermal heating wooden floors to prevent poor heat distribution 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 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 great deal of energy but also leads to excessive temperature differences between the indoors and outdoors, making the space uncomfortable and more susceptible to catching a cold.
2. In areas requiring heating, such as northern regions, it's advisable not to frequently turn the electric floor heating system on and off. As it takes time for the indoor temperature to rise, doing so not only affects the system's lifespan but also the heating efficiency. Additionally, it typically takes around two to three hours to warm up, during which the electricity consumption is high. Frequent on-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 bedroom temperature accordingly.
