As the current popular home heating system, floor heating and radiator, whether the floor heating is better or the radiator is better, there are different opinions for a while, each has its own statement, and any sound can be heard. In fact, there is no such thing as good or bad in these two systems. It is just that the house is suitable for you or not, and what is suitable is good. The following will analyze the difference between radiator and floor heating in detail from several important indicators such as installation effect, heating effect, thermal efficiency and energy saving effect. 1 What are the advantages and disadvantages of radiators Advantages of radiators
1. Fast heating
A good radiator is about 10 minutes Start to emit heat, reach the preset temperature (20 degrees plus or minus 2) in half an hour It can be used as a thermal insulation conduit without affecting the floor of the home
3. Time saving
It can be used immediately without waiting, saving time.
Disadvantages of radiators
1. Occupying space
The radiators have a certain volume, which will take up space in the home (the radiators need to be placed)
2. Comfort level
The temperature of the radiator rises quickly, and the comfort level is slightly worse than the floor heating
2 What are the advantages and disadvantages of floor heating The advantages of floor heating
1. Moderate is better:
Floor heating is heat generated from the feet. Traditional Chinese medicine calls the feet the second heart acupuncture point dense area of the human body. As the saying goes: “Cold is born from the foot”, this can be very effective for people’s rheumatism and so on.
2. Save space:
There is no heat dissipation in the room 3. The operating cost is relatively low: >
Of course, this statement has a lot to do with your usage time. Just like a car on the road, floor heating belongs to a constant speed exercise and maintains a speed all the time, while the radiator belongs to a period of time. 60M, 80M for a while, and 10M for a while, for the same itinerary, a constant speed is definitely the most energy-efficient.
4. Comfortable and hygienic:
The ground radiant heating system is one of the most comfortable air conditioning methods. The indoor surface temperature is uniform, the indoor air temperature field is reasonably distributed, and the human body perceives a high degree of comfort. At the same time, the indoor is clean and clean, which is beneficial to human health. .
5. Good stability:
Because the ground and floor heating aluminum foil layer has large energy storage and good thermal stability, it can maintain room temperature stability even under intermittent operation conditions
6. Long service life:
Floor heating pipes that meet European standards are materials that can be used continuously for more than 50 years.
Disadvantages of floor heating
1. There are requirements for floor materials
The floor materials of the floor radiant heating method mainly radiate heat into the room through the floor concrete and floor materials, so during the heating season Floor materials will always be continuously heated at a certain temperature, so it is suitable to choose stone or composite floors with good heat dissipation and material properties that are not sensitive to temperature changes. At present, solid wood floors are not suitable for floor radiant heating systems
2. Occupies a certain floor height
The insulation materials, coils, and concrete covering the coils that are not suitable for the secondary decoration of the ground radiant heating system are all laid under the ground, so it is necessary to occupy a certain floor height indoors , According to the different systems, the height of about 4~8cm is required, the electric floor heating is 4-6cm, and the water floor heating is 6-8cm. The influence of this height should be considered when choosing a ground radiant heating system. The system pipelines are all hidden and installed under the ground. It has the possibility of disassembly and replacement, so if the ground is used for the second decoration, the system will only be dismantled as a whole.

Comparison of floor heating and radiator:
1. Installation effect
Floor heating is a concealed system, and floor heating pipes are buried In the underground, it does not affect the decoration of the wall and the placement of furniture, and is not restricted by whether the wall can be fixed with brackets. This advantage is especially obvious in spaces such as floor-to-ceiling glass all around. Since the floor heating is a heating system buried in the ground, it will increase the net height of the room. Generally, the wet floor heating should be increased by 8cm, and the dry floor heating should be increased by 4cm.
The radiator heating is to install the radiator under the outer window (if it is restricted, it is installed on the inner wall). Generally, it is installed on the surface, and the pipeline is hidden under the ground. At present, radiators are generally made of steel plates, aluminum alloys and copper-aluminum composite radiators, and pipes are made of steel pipes and PEX pipes. The installation in this way occupies the horizontal space of the room and affects the placement of furniture. The installation of the radiator is restricted by whether the wall can fix the bracket.
2. Heating effect
The heat dissipation method of floor heating is mainly radiant heating, and the heat is radiated evenly from the bottom to the top. The temperature at the same level is uniform and the temperature difference is small, making people feel that the feet are hot and the head is cool, which is both energy-saving and comfortable.
The radiator heating is a convection-based heating method. The radiator first heats the surrounding air, so that the air forms convection in the room to achieve the purpose of heating. This heating method is that the temperature around the radiator is high. As the distance from the radiator increases, the temperature decreases, and the temperature difference at the same level is large. This phenomenon is especially obvious in large space rooms. Because this heating is a convection method, the hot air is convection from top to bottom, and the room temperature is hot on the top and cool on the bottom, giving people the feeling of hot head and cold feet, and the comfort is relatively poor, but it is better than air conditioning heating.
3. Thermal efficiency
Floor heating is the radiation of low-temperature hot water, and the specific heat of water is large, so the heating of floor heating is slow, especially when it is first turned on, the whole It takes a long time for the house temperature to rise, so underfloor heating is generally on 24 hours a day.
The temperature of the radiator is high, and the room temperature starts to rise in a short time, and the thermal efficiency is very high. Compared with the high-efficiency heating demand of young people, it is better for short-term heating users to choose radiator heating.
4. Energy saving effect
Floor heating is a low temperature radiation heat dissipation, the required water temperature is low, and the floor heating has the functions of temperature regulation and temperature control, which is very suitable for centralized heating. Heating may not have any advantages, but for independent heating systems or central heating systems with household metering, the energy saving effect is obvious.
Heating belongs to air convection heat dissipation, and the required water temperature is high, and most of the heating is not equipped with a temperature control device. Even if there is a temperature control system, the energy saving effect is still not obvious, and floor heating is better than heating. 30% energy saving.
