Villas, duplexes, and self-built homes with large floor areas are often chosen as retirement homes by owners. Many HVAC and renovation professionals argue that electric ground heating has a high power load, which naturally consumes a lot of electricity. Is electric ground heating only suitable for small units, and not at all appropriate for large floor areas?

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 a case of "one lie is told with a mouth, but it takes legs to refute it."

For villa, duplex, mezzanine, and self-built homes with large floor areas, electric underfloor heating systems are actually more suitable than for small residential units.

Let's summarize and analyze by addressing the common concerns from the 9 major fields of underfloor heating selection.

1、Insufficient electrical load?

Villas, duplexes, and large-area floor plans have expansive square footage, requiring a correspondingly larger electrical load. For villas or large-area 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 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's equivalent to having three 220V lines entering the home, effectively tripling the electrical load capacity.

The HOCHTIEF electric underfloor heating is suitable for别墅, lofts, and large apartment renovations, where electrical load is not an issue at all. In summary, remember this: for any house, regardless of its size, as long as it can meet the cooling electricity demand for air conditioning in summer, the power load for the HOCHTIEF electric underfloor heating system in winter is more than sufficient. To take it a step further, electricity supply can be upgraded upon application, and an increasing number of areas are gradually joining the free expansion of residential electrical load.

2The size of the house and the heated area of the underfloor heating are two different matters.

Even for villas or luxury homes over 1,000 square meters, at night, they only use one bed. With three generations of the family plus a maid, they typically need around 5 rooms. Even during the extreme summer heat, very few families see the need to turn on the air conditioning in all rooms. It's not just about the cost; it's more about whether such extravagance is necessary.

Why run the radiant heating system at full capacity during the winter, especially in rooms that are rarely used or empty at night, when family members are scarce? It's unnecessary, and in reality, it's seldom done like that.

Master of Traditional Chinese Medicine Deng Tietao emphasizes the importance of nurturing the heart and virtue, advocating for alternating temperatures to promote blood circulation, enhance immunity, boost 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 run at full load 24/7 when unoccupied.

It is clear that a misconception to be aware of is that the electrical power load and utility costs for a 300㎡ residential villa equipped with HOCHTIEF's electric underfloor heating cannot be three times, let alone double, that of a 100㎡ villa. This is not a simple matter of logic or multiplication and division. The factors that significantly impact the cost of using HOCHTIEF's electric underfloor heating are the number of family members and their lifestyle habits, rather than the location or the villa's floor plan, whether it's a bungalow, a multi-story house, a self-built house, or an apartment.

3Neglected debugging and follow-up maintenance issues

Waterfloor heating is not the same as electric floor heating. Each room in the HOCHTIEF Hochtief electric floor heating comfortable heating system is independent, with no neighboring relationships or mutual influence. In contrast, waterfloor heating systems are interconnected, resulting in different resistance in the water system across different floors, areas, and distances. This leads to varying flow rates and temperatures, and the time required to reach the desired temperature can differ significantly. The differences can be substantial. Achieving identical settings for each room in a waterfloor heating system requires genuine expertise, often relying on the dedication, professionalism, and craftsmanship of the installer. This is a common issue among many waterfloor heating users and HVAC merchants. The tuning process can take a long time, with adjustments made today and evaluated the next day, followed by further adjustments and evaluations the day after that. It may require multiple tuning sessions, and it's not uncommon for the system to need annual adjustments.

While HVAC suppliers often add equipment like booster pumps, mixing centers, and coupling tanks to increase pressure and balance water pressure to reduce the workload during the warranty period and boost profits, the issue cannot be fully resolved. Moreover, it makes the radiant heating system more complex, leading to increased installation costs for radiant heating and higher rates of system failures and maintenance costs. Most importantly, these post-warranty costs are substantial...

From the above hints, it's important to recognize that simplicity is the key to reliability, stability, and cost-effectiveness. In life, often convenience is more important than saving money.

Villas, townhouses, and self-built houses may have large floor areas, but just like air conditioning used for summer cooling, it's generally not practical to run floor heating in all rooms simultaneously during winter. This would only add unnecessary hassle, worry, and a wasteful expenditure of money that is truly not needed.

4Radiant floor heating that heats up quickly is equivalent to energy-saving use.

In many people's superficial awareness, electric radiant heating is inherently more expensive than gas-powered water-based radiant heating. If you simply calculate based on the unit cost of energy, electricity is indeed more expensive than gas. Then, it's thought that for large residential layouts like villas, split-level homes, and self-built houses, the HOCHTIEF electric radiant heating system will definitely cost more than a gas water-based heating system.

In non-traditional heating zones in southern regions of our country, we do not require a 24/7 continuous operation of the underfloor heating system, nor do we need to activate it in all rooms. With the quick-warming electric underfloor heating, its flexibility in use translates to energy savings. For instance, if 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 up slowly and cannot be easily turned off once it's on, requiring nearly 24-hour operation.

So, the energy saved on the unit price of gas boiler water ground heating is all wasted in terms of speed, simply by its own merit. When you crunch the numbers, it's not just that no savings are made; it might actually be more costly. According to an official news report from Guiyang City, the average annual gas cost for users of the gas boiler water ground heating system in Guiyang is over 9,500 yuan. Using HOCHTIEF Hochtief electric ground heating is far more energy-efficient and cost-effective than the gas boiler water ground heating system.

5、Simple and flexible installation equals safety

Villas, split-levels, jump floors, and self-built houses, although with large living space, usually have a small permanent population at home. Therefore, when it comes to the demand for radiant heating systems, not all rooms necessarily need to be equipped with radiant heating. However, with high-cost options like gas boilers or dual-water supply ground-source heat pumps, the initial cost is mainly for the main unit. Once the main unit is purchased, it seems wasteful not to install radiant heating throughout the entire house. For instance, a wall-hanging boiler costing over 10,000 yuan can cover 100㎡ or 200㎡ areas. With the major expenses already incurred, it's natural to opt for full-house radiant heating.

In certain areas, where underfloor heating is more needed in bathrooms, water-based underfloor heating cannot be installed.

For instance, the basement is used only once a year. As a result, to avoid waste, you end up creating more waste. Purchases without cost-effectiveness may seem like a great deal, but their utilization rate is actually quite low.

HOCHTIEFThe HOCHTIEF electric underfloor heating system does not require a main unit; the cost is simply calculated based on the actual area of the installation. We have also encountered large villas that only installed heating for 5 rooms, which still met the owner's needs, but it was more hassle-free and cost-effective compared to hydronic heating. We've also encountered many developers and construction bosses with private villas over 1,000㎡, including bathrooms, all of which were equipped with HOCHTIEF electric underfloor heating. It's simple, space-saving, operates on demand, and requires no maintenance.

6、The villa requires a simple heating system that is durable and highly stable.

Homeowners of small apartment units may consider future economic conditions or actual needs and may switch to a new house in the near future, so many people do not plan their home renovations with long-term foresight. On the other hand, villas, split-level houses, and large units are often chosen as retirement homes. Many homeowners have expressed their wishes: "I want to live here for the rest of my life, and I plan to retire here. You must ensure that the underfloor heating is done properly." They are more cautious in selecting construction materials. Therefore, the underfloor heating system needs to be chosen for its long lifespan, low failure rate, strong stability, and ease of use. This is not just about maintenance costs, as some items are not easily replaceable, and the underfloor heating system is a typical concealed project that is even impossible or not replaceable.

HOCHTIEFHoheitif electric underfloor heating offers lifetime maintenance-free, which is more important for owners who don't mind costs—simple, hassle-free, and convenient. In contrast, water underfloor heating systems typically have an average warranty of 2 years and a lifespan of less than 10 years. Even if there are no faults or breakdowns, regular cleaning and maintenance are required, which is not only costly but also quite麻烦.

So, for homeowners of villas, townhouses, self-built houses, and other large residential properties, we highly recommend electric floor heating. Hohetif, a brand dedicated solely to electric floor heating, was the first in the HVAC industry to announce the discontinuation of water-based heating systems in 2014. We make it easier for everyone and have been loudly promoting our far-infrared integrated electric floor heating system.

7、The impact of electric underfloor heating on construction and decoration can be overlooked.

HOCHTIEFThe Haughtif electric underfloor heating system has a simple structure and a thickness that can be as low as 2.5cm, with special cases allowing it to be as thin as 2.0cm. It doesn't occupy wall space, making it highly advantageous during renovation and installation processes.

For instance, some customers cannot install water-based radiant heating due to the inward opening of the security door and the small distance between it and the ground.

For instance, with a low ceiling height, a central air conditioning system needs to be installed, and if the radiant heating is too thick, the ceiling height becomes even lower, and you can almost touch the suspended ceiling, feeling confined.

For instance, installing heating takes up space, leaving no room for tables, wardrobes, or sofas. Many homeowners are torn between choosing underfloor heating.

For instance, the house is spacious, with numerous heating pipes for radiant heating, intersecting with water pipes and electrical lines. Some cannot be dug below, nor can they stick out, making it quite a challenge. Sometimes, routing them through the bathroom even affects waterproofing treatments.

For instance, installing a diverter may affect the installation of the bathroom cabinet and the kitchen cabinet.

So, due to the complexity of the water floor heating system, its impact on renovation is all-encompassing. Many issues only become apparent on the day they occur. For instance, in the Lantiao Community in Wuhan, Hubei Province, many residents discovered on the day they installed the water floor heating that the distance between their inward-opening security doors and the ground was insufficient. Some decided not to proceed, finding themselves in a dilemma where the heating company wouldn't refund and the property management wouldn't allow door modifications. However, none of these issues exist with HOCHTIEF's electric floor heating systems, which is why many residents in the Lantiao Community directly chose to install HOCHTIEF's comfortable heating system.

8、Long-term considerations for energy use

Electricity energy is not only a renewable resource but also one of the few energy sources that have seen no significant price adjustments in the past two decades. Currently, there is an excess of electricity production domestically, and in recent years, the focus has been on developing clean energy sources. This is because China has an abundance of electricity and there is no need to further develop polluting and energy-intensive coal-fired power plants. Therefore, in many heating areas in northern China, in accordance with the requirements of the National Development and Reform Commission, localities have implemented preferential electricity prices for electric heating.

Natural gas resources are not only non-renewable but also heavily reliant on imports, with the supply-demand contradiction increasing year by year. Therefore, in the future, the price of natural gas will only rise and not fall. The price of gasoline aligns with the international market, experiencing fluctuations in retail prices, but the price of natural gas has never decreased. In many provinces and cities, limited natural gas supply during winter has become a regular occurrence.

Notice of Beijing City's Issuance of the "Implementation Plan for Carbon Peaking in Beijing" - Beijing Government Document No. 31 [2022], which explicitly requires the prohibition of new construction and expansion of independent gas heating systems, upholds the priority principle of heating with renewable energy, and promotes the low-carbon transformation and replacement of heating systems.

As indicated above, whether from the current national carbon peak and carbon neutrality policies or from the users' long-term planning, HOCHTIEF's electric floor heating will be the trend of heating methods in the near future.

9、Have heard that electric radiant heating emits radiation and can cause electric leakage? Scared to use it?

This "rumor" is quite bizarre, but it has to be said that it's preventing users from choosing.HOCHTIEFHaughton Electric Floor Heating SystemsOne of the major killing forces

Now, globally in obstetrics and gynecology departments, forNewbornCare and warmth for premature, critically ill, and weak infants are provided through an electrically heated far-infrared radiant heating system, ensuring continuous warmth for newborns. National Standard Term: Infant radiant warmer, also known as "radiant neonatal resuscitation bed," "infant radiant warming bed," etc.

Over the years, we've heard numerous customer feedback that using your far infrared electric ground heating systems during winter has significantly reduced colds among family members of all ages. Virtually all users of electric ground heating systems from various manufacturers have never experienced any personal injury due to electromagnetic radiation, and in the past 20-plus years, there have been no reported cases of personal injury caused by electric ground heating system leaks. In contrast, in the water ground heating sector of competing products, issues like leaks, drips, and poor after-sales service, delays in after-sales support, and unregulated service fees are common. The water ground heating system involves many components, with manufacturers, ground heating salespeople, and users often bickering and shirking responsibility, as well as issues with gas boilers and more, popping up endlessly.

Many HVAC professionals or property owners might ask, "Why isn't electric radiant heating as widely adopted as water-based systems if HOCHTIEF's electric radiant heating system is so excellent?"ChooseHOCHTIEFHaughton Electric Floor HeatingWhy are the users still a minority?Perhaps it's an instinctive misinterpretation or stubborn rejection, compounded by the defamation from competitors in the water ground heating industry.Electric underfloor heating can cause air dryness and discomfort; will the power of the electric underfloor heating degrade? It won't be long before you need to install a separate water heater as well, etc.The sales and distribution services for electric ground heating systems do not yield a profit margin as high as water-based ground heating systems, and lack a sustainable profit space for subsequent maintenance, repairs, and cleaning. This may also be a real stumbling block on the development path of the electric ground heating industry.

As the country's "carbon peak and carbon neutrality" strategy continues to advance, HOCHTIEF's electric radiant heating, as a safe and low-carbon heating method, will have greater development potential. HOCHTIEF will delve into continuous innovation in areas such as energy efficiency assessment, heating system design optimization, online temperature monitoring, and intelligent control systems.

Over the past century, HOCHTIEF has established the gold standard for residential and commercial space heating systems with the application and development of far-infrared heating technology for neonatal radiant warming beds, making the temperature adapt to you, not the other way around.
