What are the types of underfloor heating? What are the specific advantages and disadvantages?

It can be divided into two categories: electric floor heating and water floor heating. Water underfloor heating will soon be replaced by electric underfloor heating.

1. Electric floor heating is environmentally friendly and energy-saving. Electric floor heating is to convert 100% of the electric energy into heat energy, and the energy loss is zero, and the water heating needs to promote the water as a medium to circulate indoors, from the boiler to the water collector to the water pipe, there are various mechanical energy losses, therefore, under the premise of the same heat supply, the cost ratio of electric heating and gas water heating is about 1:3.

2. More comfortable to use. Electric underfloor heating is to bury the cables directly under the floor, leaving only a beautiful thermostat on the wall, which does not take up any other space and is used without any noise. Intelligent temperature control can set a variety of time control modes, independent control of rooms and households, and the use of humanization.

The water floor heating is composed of boilers, water collectors, pigs and other components, which occupy a large indoor space, are not beautiful, and are noisy to use. It is impossible to achieve independent control of sub-rooms and households in the true sense.

3. There is no need for any later repair and maintenance, and there is no worry about use. The service life of the well-known brand of electric floor heating can reach more than 50 years, and the same life as the building, if the cable is damaged due to improper use or man-made damage, the dead pixels are locked in the range of a floor tile through professional testing instruments, and only need to pry open a floor tile for maintenance.

And every component of water floor heating has maintenance and has a different service life. The life of imported boilers is 7-10 years. Parts such as manifolds have a shorter lifespan.

Once the water pipe is damaged, it cannot be repaired, and the entire ground can only be pry open and replace the water pipe and install it from the beginning. It will cause greater economic losses to users and bring a lot of trouble.

In addition, the safety of water underfloor heating is low. Once there is water seepage in water and floor heating, the danger is very high, and if the water seepage reaches the low wall socket or the ground plug-in board, it is easy to have a safety accident.

Hello, in fact, the floor heating industry, you know.

Among the many home heating methods, floor heating has always been very popular, and its health, comfort, energy saving and other characteristics have attracted the attention of many families and have become the installation choice of many people. So, what are the categories of our common underfloor heating systems? What are their advantages and disadvantages?

Below, let me give you a brief introduction.

The floor heating system uses the entire ground as a radiator, transmits heat from the bottom to the top through the heat medium in the floor mezzanine, and uses the heat transfer principle to maintain the indoor temperature within a comfortable range, so as to truly warm enough and cool up. According to the different thermal medium qualities, floor heating is divided into two types: water floor heating and electric floor heating, which are different and have their own advantages and disadvantages, including:

1. Working principle.

Water floor heating uses hot water with a temperature of no higher than 60 as the heat medium, circulating flow in the pipe to heat the floor, and heating upwards through the ground in the form of radiation and convection heat transfer; Electric floor heating uses a low-temperature heating cable as a heat source to transfer heat, and uses a thermostat to adjust the temperature.

2. Advantages and disadvantages of water floor heating.

Advantages: The water floor heating with low-temperature hot water as the medium is stable, and its comfort is higher than that of electric floor heating, which is suitable for families with elderly and children; It will not produce radiation during operation, which is stable and safer; The floor heating pipe has the same life as the building and has a long service life; Take into account domestic hot water; The larger the usable area, the more energy-saving; After more than 20 years of development, the installation and maintenance technology is more mature.

Disadvantages: Due to the slow flow rate of hot water and the low temperature of the return water, its heating rate is also slow; The early installation cost is high, and the wall-hung boiler accounts for the majority; Maintenance is troublesome, and floor heating pipes and wall-hung boilers need to be cleaned and maintained regularly.

3. Advantages and disadvantages of electric floor heating.

Advantages: With the heating cable as the heat source, the heating speed is fast, and the indoor heating rate is faster than that of water floor heating; The wiring is more aspect, and there is no need to occupy too high a floor height; There is no need for later cleaning and maintenance, which is more convenient; It is more energy-efficient to use in a small area; The service life is long, and the theoretical service life of carbon crystal floor heating can reach more than 50 years.

Disadvantages: The non-regret code shooting method takes into account domestic hot water, and a water heater needs to be set up; Slight radiation is generated during operation; Large-scale use, in the long run, its energy efficiency is not as good as water floor heating; Once there is a bad area, it needs to be replaced.

Whether it is water floor heating or electric floor heating, each has its own advantages and disadvantages, there is no good or bad, just look at whether it is suitable or not.

Floor heating is one of the common heating systems in life, compared with heating and air conditioning, what are the advantages of floor heating? Let's find out.

Advantages of underfloor heating

1. Uniform and comfortable heat dissipation, the heating principle of the floor heating system is radiation heat transfer, compared with air conditioning, heating and other hot air heating through forced convection circulation, the dust flow in the air is much smaller, which reduces the spread of harmful germs in the air, and the indoor environment is more hygienic and clean.

2. Clean and healthy, the floor heating system can effectively promote foot blood circulation, thereby improving the blood circulation of the whole body, promoting metabolism, and inhibiting cardiovascular diseases; It is especially suitable for the elderly and children, and it has more prevention and treatment effects for patients with arthritis and cold legs.

3. Environmental protection and energy saving, the floor heating system heating is about 30% energy-saving compared with the traditional convection heating method, the heat loss of floor heating in the transmission process is small and the heat is concentrated in the height of the human body, even if the indoor set temperature is lower than the convection heating method, it can also make people have the same warm feeling. Underfloor heating can fully save energy and does not emit any noise, which is very environmentally friendly and energy-saving.

4. After the installation of the whole system, there is no longer an electric heating sheet in the room, which virtually increases the indoor use area.

5. Efficient sound insulationAt present, China's floor slabs generally use prefabricated slabs or cast-in-place slabs, which have poor sound insulation effects, while floor heating increases the insulation layer, which has a very good sound insulation effect, can reduce noise pollution, and there is no noise in the heating process, which is conducive to the physical and mental health of the family.

In general, the advantages of floor heating include uniform heat dissipation, comfort, cleanliness and health, environmental protection and energy saving, beautiful and generous and efficient sound insulation, etc., which is a better heating choice for modern residential areas.

Advantages of underfloor heating

1. Comfort, health and health care function: the full name of floor heating is low-temperature radiant floor heating, which is the most comfortable heating method so far, the indoor surface temperature is uniform, and the room temperature gradually decreases from bottom to top, giving people a comfortable feeling of warm feet and cool heads; Because the hot air rises naturally, there is no air agitation, it is not easy to cause polluted air convection, and the indoor air is clean; Improves blood circulation and boosts metabolism.

2. Floor heating does not occupy space, and the use of the living room is more flexible: Floor heating is a concealed project, and there is no radiator and branch pipe to occupy space, which increases the usable area of the living room from the side.

3. Superior energy saving: the radiant heating method of floor heating has higher thermal efficiency than the convection heating method, and the heat is concentrated in the height of the human body; Small heat loss during transmission; Users can also flexibly adjust according to their own usage to further effectively save energy.

4. Good thermal stability: the ground layer and concrete layer of floor heating have strong heat storage capacity, and the indoor temperature changes slowly under the condition of intermittent heating.

5. Low operating costs: about 20% energy saving compared with other heating equipment, which can make full use of low-temperature hot water resources or use electricity price policies to reduce operating costs.

6. Long service life: the plastic pipes or heating cables used in floor heating are buried in the ground, with good stability, no corrosion, no human destruction, and the service life is synchronized with the building. It can also save maintenance costs for users.

Disadvantages of underfloor heating:

1. Floor heating does not occupy space and occupies the floor height: floor heating occupies a floor height of 5-7 cm (the selection of insulation materials, floor heating pipes is different, the construction plan and method are different, and the impact on the floor height is different).

2. It is not easy to maintain: floor heating is a hidden project, and materials with good pressure, temperature and corrosion resistance and good thermal stability should be selected when decorating. It is not convenient for secondary decoration, because the pipeline is laid underground, and when the ground is transformed, it is easy to damage the underground pipeline.

And it is not suitable to lay decorations on the floor, which is easy to affect the heat dissipation effect.

3. The use of the toilet is limited: due to the complexity of the heating pipeline of the floor heating, for the sake of waterproofing, the floor heating coil must be waterproof before and after laying, due to the small laying range of the bathroom (such as to reserve the toilet, bathtub, drain, etc.), the room temperature often does not meet the heating standard, and it needs to be supplemented by radiators.

4. When the floor heating system is in operation for 2-4 years, the floor heating pipeline produces scale, which needs to be cleaned by professional equipment, otherwise it will directly affect the heating effect.

It is not good for physical health, the temperature is high, the air is dry, and the static electricity is serious. It is very bad for the respiratory system.

This episode of the program shares the experience of using floor heating, and compares electric floor heating and water floor heating in all aspects of cost maintenance. This is the last episode, and the next episode will introduce the installation and precautions of floor heating construction.
