Floor heating can be described as the savior of our northerners in winter. Every family has to have it to survive a warm winter.
Once upon a time, floor heating was like a big star known to thousands of households, and it was always discussed by everyone after dinner.
The residents of the old houses have to be renovated and replaced with geothermal energy, and the young people who buy new houses have to add a few more groups on the basis of the original geothermal energy, which seems to be our respect for winter.
However, over time,This big star seems to have gone out of his way. More and more people feel that there are many problems with geothermal heat.
As a product of high technology, as a family warm baby who was once a smash hit, why is it now scolded? Is it in someone's way?
Let's reveal the truth today!
Speaking of the origin of floor heating, it probably starts from the 60s BC. At that time, the underfloor heating was called "fire kang and fire wall." Later, this kind of kang was generally used in homes in northern China, and it has always been available today.
With the passage of time, China's scientific and technological workers began to further study floor heating. Based on the radiant floor heating technology, the research was put into practice.
The Forbidden City, located in the capital of our country, uses this form of geothermal heating. Subsequently, some large buildings, showrooms and public spaces began to use geothermal technology.
It can be said that geothermal technology is a major embodiment of China's progress, with the development and popularization of society, the popularization of floor heating is getting faster and faster, and all residences have begun to become geothermal as the standard.
Thousands of homes and streets have become warmer because of the geothermal heat.
Since the 21st century, there have been more types of geothermal energy, and different types of geothermal energy can be selected according to a variety of living environments and needs.
1.Water underfloor heating.
The northern region is generally dominated by water and geothermal heating, which has a lot to do with the climate and environment of the north. The heating temperature of water underfloor heating is generally not higher than 60 hot water as the heat medium.
The heating effect is achieved by circulating heating through heating pipes buried under the ground, and heat is dissipated through the floor to the entire room.
2.Electric underfloor heating.
Electric underfloor heating is designed primarily for the south, which does not have a similar climate like the north, which is consistently cold in winter.
The temperature difference in the south is different, so it is very ideal to use this electric underfloor heating as a non-central heating area in the south. It is more effective than air conditioner heat dissipation.
Electric floor heating is buried under the floor through a heating cable as a medium, heat dissipation through the floor or tiles, and then the temperature is controlled by a thermometer, generally below 65.
3.Graphene underfloor heating.
Graphene floor heating covers more places, such as apartment buildings, hospitals, schools, high-temperature steam rooms, etc.
It works by burying the graphene heating film in the ground and heating it evenly through the floor or tile from the bottom to the top.
Due to the strong thermal conductivity, fast heating and strong stability of graphene, it far exceeds water floor heating and electric floor heating in terms of working performance. As a result, it has a wider range of applications.
The rapid development of society has made geothermal energy rapidly popularize to every household, so why do people like geothermal living environment so much, and why is this? Presumably it must have a lot of advantages and featuresLet's take a look at the advantages and characteristics of geothermal energy.
1.Warm and cozy.
Geothermal heat provides a uniform and comfortable temperature, and there is some truth to the saying that "the feet warm the whole body".
The scientific design concept of floor heating is to evenly dissipate heat from the bottom up, which not only has good air circulation, but also brings people a very comfortable temperature.
2.Doesn't take up space.
Old-fashioned radiators need to leak into the walls of the house, which not only takes up space but also is not beautiful.
Floor heating is done by burying it under the floor or tiles, so that we can feel the warmth and keep the interior beautiful and tidy.
3.Good stability.
Due to the nature of the geothermal configuration, its stability performance is very strong. The energy storage is relatively large, and it can also maintain a constant temperature in the room during the intermittent time of heating.
4.Long service life.
Geothermal stability is high, so it has a longer service life. Buried geothermal pipes are less susceptible to corrosion.
In the process of heat transmission, it is not easy to be damaged, the loss rate is very low, and the service life of a qualified floor heating pipe can be as high as 40 years.
Floor heating has its own heating system, which is composed of 4 parts, namely the heat source, the transmission pipeline, the control system and the heating end.
Floor heating is a big project, it not only brings us the advantages of comfort and warmth, but also has some problemsSo, what are the problems and shortcomings of geothermal energy? Let's take a look.
1.Cleaning is relatively cumbersome.
The assembly process of geothermal energy is complex and time-consuming, and the assembled geothermal heat provides a comfortable temperature for our home. However, geothermal energy can produce impurities and bacteria over time, which requires regular cleaning.
The retention of perennial water causes a large amount of dirt to be inside the geothermal pipes, which can breed a large number of bacteria in the pipe walls.
This is a great danger to our health, but geothermal cleaning is not an easy thing to doThere is no way for us to do this personally, and we need to find a professional master to help us clean it.
Clean geothermal is a time-consuming and expensive project, so clean geothermal can be said to be a major disadvantage of using geothermal energy.
2.Repairs are more complicated.
Geothermal energy is especially important when choosing. A good geothermal pipe material is not prone to problems and has a long service life. If the geothermal material is not very good, then the maintenance problems faced in the later stage are very complicated.
Geothermal is an underground hidden heating system, which is formed once in our renovation of the house, once the heating pipe leaks or other conditions, it is necessary to destroy the indoor floor or tile.
3.Space usage is limited.
As we all know, geothermal heating is the laying of geothermal pipes on the ground, but for a space as narrow and complex as a bathroomWhen laying, it is necessary to pay attention to waterproof treatment, otherwise there will be great trouble in subsequent use.
Secondly, the small space is not particularly ideal for the heating effect, so the use of geothermal space is still subject to some limitations.
4.Occupancy floor height.
When many residents lay geothermal heat, they are very concerned about the problem of floor height. Because in the house we live in, if the floor height is too low, it will affect the comfort of the whole residence.
Long-term living can also make people feel depressed, but no matter what kind of geothermal paving is sure to occupy the floor height.
Because in the whole process of laying geothermal energy, it is necessary to do thermal insulation, heat dissipation layer, protective layer and leveling layer on the ground, etc., and these constructions will inevitably occupy the floor height.
In everyone's mouth, the geothermal heat, which is full of praise in everyone's mouth, comfortable and warm, beautiful and easy to use, I don't know when it began to become scolding, what kind of problem does this exist?
On the one hand, due to the perennial use of everyone, the shortcomings from the initial beauty and comfort to the geothermal heat are shown little by little.
And there are many news reports that living in a geothermal environment for a long time is prone to "geothermal legs", which has a great impact on physical health.
Thermal radiation from the ground,It has caused many people to have leg discomfort, which has greatly reduced the once smash hit geothermal in everyone's hearts.
On the other hand, from the perspective of competition from other heating facilities, the rapid rise of the geothermal industry will inevitably lead to the decline of other competing products. The traditional heating method has been severely hit, and the conflict of interests in this has also become apparent.
For real estate developers, the cost of rent geothermal renovation is relatively high, which also increases the cost of housing construction, and from the perspective of profit maximization, developers will also recommend some other lower-cost heating solutions.
Not only that, but the rapid development of the times makes the future full of uncertainties. The continuous upgrading and change of technology and policies will affect the changes in some industries.
I think it's the most suitable choice today, and tomorrow I may have new ideas, which are full of uncertainties and can't be said.
Under the warm aura of floor heating, there is also the shadow of reality looming. Underfloor heating is like a double-edged swordIn addition to bringing us a warm and comfortable life, there are also big problems.
The discussion of geothermal issues is not only from the perspective of comfort and warmth, but also from the perspective of society and the future sustainable development path.
I believe that in the future geothermal development industry, it must be full of infinite possibilities.
Geothermal energy, which was once a smash hit, has now been questioned and abused. Faced with such a situation, we should look at this issue in a multidimensional way.
The rise and development of a product will be full of countless problems and challenges. In this era of rapid development, whether it is geothermal or other heating methods, the ultimate purpose of our choice must be to live warmly and comfortably in the cold winter.
The problem of geothermal energy is not only a problem of itself, but also from this development, we can also see the interconnection and influence between the market, technology, policy, enterprises and so on.
Therefore, when choosing heating products, first consider your actual needs and fully understand the advantages and disadvantages of various heating methods.
Second, don't blindly follow and stay vigilant. Finally, keep up with the progress of the times and policy changes, and make choices for your own needs from multiple channels.
So, for the future development trend of geothermal energy, how do you think it can be more suitable for our living requirements?
