Villas, split-level homes, and self-built houses, among other large floor plans, are often chosen as retirement homes by owners. Many HVAC or renovation professionals argue that electric underfloor heating has a high electrical power load, which naturally consumes a lot of electricity. Is electric underfloor heating only suitable for small floor plans, and even less suitable for large floor plans?
Large apartment units are more suitable for electric underfloor heating than small apartment units.
Actually, this can only be attributed to a lack of understanding or misunderstanding of the electric floor heating system, or even... it's merely a subjective judgment based on one's own assumption! Truly, it's a case of "a lie gets halfway around the world before the truth has a chance to put its shoes on"!
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 cognitive exploration.
2. Not enough power load?
Villas, townhouses, and spacious floor plans have larger areas, which necessitates a higher electrical load capacity. For villas or large floor plans, to accommodate the electrical load for air conditioning and home appliances, they typically require a 380V power supply. However, HOCHTIEF's electric underfloor heating operates on a standard 220V household appliance voltage. The 380V system, which is three-phase and four-wire, consists of three live wires and one neutral wire, with each live wire being 220V apart from the neutral. This means that 380V is not just a higher voltage but equates to having three 220V lines, effectively increasing the electrical load capacity for functionality.
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㎡, the family of three generations, including the保姆, only uses about 5 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 costs; it's more about whether such extravagance is necessary.
Why run the underfloor heating system at full load during winter, especially in rooms that are rarely used or unused most of the time, or in the hall after everyone has gone to bed? It's unnecessary and actually, it's seldom used this way.
Dr. Deng Tietao, a renowned Chinese physician, emphasizes the importance of nurturing the mind and moral character in health preservation. He advocates for alternating temperatures to promote blood circulation, enhance vitality, and alleviate fatigue. Even in the very cold Hulun Buir region of China, where the city of Genhe is located, houses have excellent thermal insulation, so they do 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 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 achieved over different time frames, with significant discrepancies possible. Achieving a uniform setting for each room requires real skill, especially for water-based radiant heating, where only relying on a dedicated, responsible, and meticulous installer can ensure satisfactory results. This is a common issue among many water-based radiant heating users and HVAC merchants. The tuning process often takes a long time, requiring multiple adjustments. Sometimes, it's not a one-time fix; some systems even require annual tuning.
And HVAC merchants often add booster pumps, mixed water centers, coupling tanks, and other equipment for increasing pressure and balancing water pressure to reduce the debugging workload during the warranty period and increase profits. However, the problem is not resolved; instead, it complicates the radiant heating system, leading not only to increased installation costs for radiant heating but also to higher system failure rates and maintenance costs for the radiant heating equipment. 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, split-level homes, and self-built houses may have large floor areas, but just like air conditioning used for summer cooling, it's generally unnecessary to run all the underfloor heating at once during winter. This adds unnecessary hassle, wasted effort, and meaningless expenses that are really not needed.
4. Rapidly heating radiant floor heating is equivalent to using energy-saving.
In non-traditional heating areas 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 turn it on in every room. With its quick heating, electric underfloor heating offers flexibility in use, which translates to energy savings. For instance, if used for 12 hours a day, the electric system would only need to be on for 12 hours, whereas a hydronic heating system cannot achieve this, as it heats slowly and is difficult to turn off once it's on, requiring almost constant operation.
So, while natural gas water ground heating saves energy per unit price, it all ends up being wasted in speed due to its capabilities. When you crunch the numbers, not only is there no savings, it might even be more costly. According to a report from Guiyang City, the average annual gas 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 homes, maisonettes, and self-built houses, although spacious, typically 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 initial cost is usually high, starting 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 100㎡ or 200㎡ areas. With the significant expenses already incurred, it's natural to opt for full-house underfloor heating.

Before 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 normal operation of the system after concealment. The concealed part should be drawn on-site with a concealed engineering drawing to facilitate the user's understanding of the installation of the carbon fiber electric floor heating products and avoid damage to the system structure due to house repairs.

Carbon fiber electric floor heating installation details are crucial:
Before installing carbon fiber electric floor heating, the construction crew should first conduct a site inspection, check the installation area to confirm it meets the construction requirements, design the plans, and then install according to the plans. Prior to installation, clean the installation area, lay the cement mortar heat storage layer as per design requirements, create a moisture-proof isolation layer, install the ground decorative materials, and complete the ground construction.

Electrical underfloor heating usage instructions:
1. After the installation of the ground heating system is completed, gradually increase the temperature 24 hours later. Ensure the floor is clean and dry before heating to prevent cracking and warping due to rapid temperature rise.
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℃ rise per hour. This allows the wooden floor to gradually adjust to the temperature change. Rapid heating may cause the wooden floor to heat up too quickly, leading to instability, warping, and cracking, which can affect the lifespan of the wooden floor.
3. Avoid fixed decorations or placing furniture without legs on geothermal heating wooden floors to prevent poor heat dissipation in localized areas. This can trap heat in the wooden floor, causing uneven heating and potential warping of the floorboards.

Electric floor heating advantages:
1. Compact Footprint: Electric radiant heating is installed beneath the floor, saving 3-5% of indoor space compared to traditional underfloor heating, without affecting the actual living area.
2. Energy-saving effect: Heat transfer is the primary method during the heating process, compared to traditional convection heating, with less heat loss, saving up to 15% of energy consumption.
3. Long lifespan: Most electric floor heaters have a lifespan of around 50 years.
4. Comfort & Hygiene: Post-installation, low surface flooring material requirements, ensuring comfort, while also preventing dust phenomena associated with convective heating systems such as air conditioners and radiators.
