Advantages of using underfloor heating

Thread Content

1. High efficiency and energy savings: When geothermal heating is used in the hall, the temperature distribution is relatively uniform throughout the height, resulting in a small temperature gradient and reduced unnecessary heat loss. Practice has shown that geothermal heating systems achieve high thermal efficiency, with heat concentrated at a height where it benefits the human body. Under the same conditions of warmth and comfort, the temperature setting for floor heating can be 2–3°C lower than that of other heating methods. Technical data shows that reducing the indoor temperature by 1 degree Celsius can result in nearly 10% energy savings. Floor heating and cooling using water-source heat pumps or ground-source heat pumps require an installed power of no more than 15 W/㎡, which is 30–50 W/㎡ less than that of air conditioners, thus helping to alleviate the power supply strain during summer. Since the floor itself is a surface for thermal radiation, it reduces the heat absorption and energy consumption of the cold surfaces in the building envelope by nearly one-fifth. 2. Uniform temperature: In the case of low-temperature floor radiant heating, the heating pipes are buried underground to raise the temperature of the ground surface, which in turn releases heat into the room; as a result, a layer of warm air is formed below 1.8 meters. This ensures both a constant room temperature and a uniform temperature distribution throughout the entire room. 3. Comfort and aesthetics: Ideal heating – The best approach for both human health and heating efficiency is one in which the temperature decreases gradually from bottom to top. Floor radiant heating is the method that comes closest to this ideal scenario. With geothermal heating, the temperature on the indoor floor remains uniform, while the indoor temperature decreases gradually from bottom to top, providing a pleasant sensation of warm feet and a cooler head. When people stay on the warm floor, their feet stay warm while the upper part of their body is protected from cold radiation, resulting in great comfort. The indoor temperature is uniform, with minimal temperature differences and a reasonable gradient, thereby heating the foot area of the body where cold is felt most easily, meeting the physiological needs of the human body ； It does not take up indoor space, allowing for the full display of personalized decoration styles. 4. Cost savings on maintenance: Floor radiant heating requires only regular cleaning of the filters. Since the heating coils are completely buried in the floor slabs, there are virtually no maintenance issues during operation, provided no damage is caused intentionally. With a service life of over 50 years, it does not corrode or scale, thus helping to save on maintenance costs. 5. Sound insulation and environmental protection: At present, precast or cast-in-place slabs are generally used for floors in China, and their sound insulation performance is not very satisfactory. The use of underfloor heating along with an insulating layer results in excellent soundproofing, helping to reduce noise pollution. 6. Health and safety: It prevents dust from being raised due to air convection indoors, reduces air pollution, and eliminates dust accumulation as well as unpleasant odors from cooling equipment and pipes ； Use low-temperature heating with water at 40–60°C to avoid burns. Floor heating is an emerging building material industry that has gained popularity in recent years; from the moment it was introduced to the market, it was well-received by many consumers. Although underfloor heating has a high installation cost and is relatively difficult to maintain, its obvious advantages are sufficient to make up for everything. It can be said that underfloor heating represents the future direction for heating systems in the commercial housing market, and it will also become a new force in the flooring market.
