Villas, split-level homes, and self-built houses, among large-area floor plans, are often chosen as retirement homes by owners. Many HVAC or 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 apartments, and even less suitable for large-area floor plans?
Large apartment units are more suitable for electric underfloor heating than small apartment units.
It's actually a lack of understanding or even a misconception about the electric floor heating system, or perhaps even... mere subjective judgment based on ego! Truly, it takes one to spread a rumor and another to run around debunking it!
For villa, duplex, mezzanine, and self-built houses with large floor areas, electric floor heating systems are actually more suitable than for small residential units.
Let's summarize and analyze, focusing on the 9 common fields of radiant heating selection issues for in-depth understanding.
2. Not enough power load?
Villas, split-level homes, and large-area floor plans have expansive square footage, which necessitates a correspondingly larger electrical load. For villas or large-area floor plans, to accommodate the electrical load for air conditioning and household appliances, they typically require 380V power supply. However, HOCHTIEF's electric underfloor heating uses the standard 220V household appliance power supply. 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 isn't just about higher voltage; it's equivalent to having three 220V lines, roughly equal to an increased electrical load for functionality.
2. The size of the house and the usable area of the underfloor heating are two different matters.
Even for villas and luxury homes over 1000㎡, the family of three generations, including the babysitter, only uses about 5 rooms for rest at night. Even during the peak summer heat, it's not common for many families to turn on the air conditioning in all rooms. This isn't just about costs; it's more about whether it's necessary to be so extravagant.
Why run the underfloor heating system at full capacity during winter, especially in rooms that are rarely used or empty most of the time, like the living room after everyone has gone to bed? It's unnecessary, and in reality, it's seldom used this way.
Traditional Chinese medicine practitioner Deng Tietao emphasizes the importance of nurturing the heart and virtue in health preservation. He advocates for alternating between cold and hot to promote blood circulation, enhance vitality, and alleviate fatigue. Even in the extremely cold Hulunbeier Genhe City in Inner Mongolia, China, due to the good thermal insulation of the building structure, the house does not need to operate at full capacity when unoccupied.
3. Often Overlooked Troubleshooting and Post-Maintenance Repair Issues
Water-based radiant heating is not the same as electric radiant heating. Each room in HOCHTIEF's HOCHTIEF electric radiant heating comfortable heating system is independent, with no neighborhood relationships or mutual influence. In contrast, water-based radiant heating is interconnected, leading to different resistance in the water system across different floors, areas, and distances. This results in varying flow rates and temperatures, as well as different times required to reach the desired temperature, which can be significantly different. 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 relies on the dedication, professionalism, and craftsmanship of the installer, a common issue among many water-based radiant heating users and HVAC merchants. The adjustment process can take a long time, often requiring multiple attempts over several days, as the heating effect is assessed and adjusted accordingly. It's not always a one-time fix, with some systems needing annual adjustments.
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. However, this does not solve the problem and actually complicates the radiant heating system, leading to higher installation costs for the ground heating and increased failure rates and maintenance costs for the equipment system. More importantly, these post-warranty costs are substantial...
From the above hints, it's crucial to recognize that only the 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 just like air conditioning used for summer cooling, it's generally not advisable to simultaneously activate underfloor heating in all rooms during winter. This leads to unnecessary hassle, time-consuming efforts, and a wasteful expenditure of funds 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 continuously running 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 we use it for 12 hours a day, we only need to turn it on for 12 hours. In contrast, a hydronic heating system cannot achieve this; it heats slowly and cannot be easily turned off once it's on, essentially needing to be left running.
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 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, split-level, mezzanine, and self-built houses, despite their large floor area, usually have a significant number of residents. Therefore, when it comes to the demand for underfloor heating systems, not all rooms necessarily need to be equipped with underfloor heating. However, with dual-fuel options like natural gas or air-source heat pumps, the initial cost is usually higher for the main unit. Since the main unit has been purchased, it seems wasteful not to install full-house underfloor heating, especially when considering a wall-hung boiler that costs over 10,000 yuan and can cover areas of 100㎡ or 200㎡. With the higher costs already incurred, it's natural to proceed with the full-house installation.

Electric Underfloor Heating Usage Guidelines:
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 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, aiming for about 1℃ per hour. This allows the wooden floor to acclimate to the temperature rise gradually. Rapid heating may cause the wooden floor to expand and warp, leading to cracking and instability, which can affect the lifespan of the flooring.
3. Avoid fixing decorative elements or placing furniture without legs on geothermal heating floorboards to prevent poor heat distribution in localized areas. This can trap heat in the floorboards, causing uneven heating and potential warping of the wood.

Electric Underfloor Heating Advantages:
1. Small footprint: Electric underfloor heating is installed beneath the floor, compared to traditional radiant heating, it saves 3-5% of indoor space without affecting the actual living area.
2. Excellent energy-saving effect: The heating process primarily relies on heat transfer, resulting in less heat loss compared to traditional convection heating, saving 15% of energy consumption.
3. Long Service Life: Most electric radiant heating systems have a lifespan of around 50 years.
4. Comfort & Sanitation: Post-installation, low surface material requirements ensure comfort, while also avoiding dust issues associated with convective heating systems like air conditioners and radiators.

Prior to installing the carbon fiber electric floor heating system, the insulation resistance and rated 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 installation, 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 sections should be sketched on-site as a concealed works drawing to facilitate users in understanding the laying of the carbon fiber electric floor heating products and avoid damaging the structural layers of the system due to house repairs.
