Floor heating is really not too strange to all of you. Here are the questions that Yi Lee didn't answer logically. If other students have any questions, please feel free to ask them (thank humbly):
1 floor heating price?
Floor heating (water) consists of heat medium+transmission equipment+terminal cooling equipment. The heating medium is our gas wall-hung boiler, the conveying equipment is our distribution main pipe and the main equipment under the boiler (generally including our coil), and the terminal cooling equipment is our coil or radiator.
As for electric heating, heating cable, carbon crystal plate and carbon fiber electric heating film, they all have a series of brands, so the price depends on the quality of their materials. At present, the best electric heating material comes from South Korea, and the price is basically stable at around 2 10 per square meter.
2. What is the monthly steam burning cost?
Calculation of monthly gas cost;
Heating area * heat distribution per square meter * Joule coefficient * seconds per hour
-
The electric heating capacity is 860J╱/water, and the heating gas consumption is 8600J.
The final answer is how much energy is consumed by multiplying their unit costs respectively. In fact, the floor heating only works for 6-8 hours every day, and almost all other time periods are non-working heat preservation time. Some students say that electric heating is more energy-saving than water heating, so Li Yi has to wait and see, which is quite talented.
That brand is good (this is what I am most worried about. Only a brand with a certain reputation can reassure people, but there seems to be no well-known brand for floor heating at present)
Now many students can answer this question: Weineng, wiesmann, Beretta and Bosch. ......
All of the above are gas-fired wall-hung boilers and water heating. Of course, there are also pipes: Oriental, Jinde, Teana and George Fisher. ......
Electric heating brands: Daewoo, Anze, Danfoss, Nixon, Hanks. ......
4, after-sales service (because it is buried under the floor, if something goes wrong, it will be in big trouble)
This is the biggest problem and the least problem of floor heating. This has been the case in the north for decades, and there are few water leakage incidents. Even if the water leakage is man-made damage, Li Yi has done experiments before. Rolling with a car and knocking with a hammer did not damage the pipeline, and it was insured by the manufacturer. Yi Lee is currently insured for 50 years. However, objectively speaking, no matter how good things are, they can't guarantee the safety of 100%. They just tried their best to avoid and stop this incident. At present, Li Yi has not done it, nor has he heard of water leakage here.
5. Does water heating only burn natural gas? Can I use something else?
Of course, we can also use others, such as our solar energy, electric boiler and carbon boiler, but as a decoration sketch in Chengdu, gas wall-hung boiler is the best choice in terms of usage habits, installation and energy efficiency.
6. Can each room be controlled separately?
It can be independently controlled and accurately adjusted according to the temperature of each room.
7. What is a circulatory system?
The way to achieve the purpose of heating by circulating low-temperature water (60℃) in buried pipes or radiators is called water heating.
8. What is the composition of the circulatory system?
Water heating consists of heat source+transmission equipment+terminal cooling equipment.
Gas wall-hung boiler+valve main pipeline transmission+pipeline (radiator)
9. Is there a national standard for floor heating?
Technical specification for floor radiant heating
10 floor heating or radiator, which has a longer service life?
In terms of service life, there must be a basis. Judging from the quality assurance alone, the floor heating pipe is pressed against the bean stone heat storage layer, and the radiator belongs to the external type. The maximum warranty period of the floor heating pipe is 50 years, and the maximum warranty period of the radiator is 12 years.
With electric heating, the maximum coverage period is 10 years, not 50 years as some students said.
1 1. What is the finished surface of floor heating?
The finished surface of decoration plumbing pipes and floor tiles is about 10 cm, and the floor is about 8 cm.
The finished surface of heating cable is about 5 cm, and the electrothermal film is about 3 cm.
12, will floor heating radiate downward?
Hot air is light and spreads from bottom to top. Whether it is water heating pipe, electric heating cable or electric heating film, there will still be a small amount of heat loss around itself, so insulation layer and reflection layer will be made during installation.
Floor heating structure layer:
13. What problems should be paid attention to in the operation and management of floor heating?
Live equipment does not need to be plugged and unplugged at any time. Pay attention to waterproof and heavy impact. Please refer to all electronic products for the precautions of the control panel.
14. What are the restrictions and requirements of the floor heating system for floor materials?
Floor heating is a process of heat transfer, and the most important thing is of course the thermal conductivity. From high to low, the common heat transfer coefficients of ground materials are:
Natural stone? & gt？ Tiles? & gt？ Solid wood composite floor? & gt？ Reinforced floor? & gt？ Solid wood floor? & gt？ Chemical fiber carpet? & gt？ Pure wool carpet
I don't think from the solid wood floor. Now the floor is made of many composite materials. When choosing it, I must choose environmental protection.
15. Can floor heating and radiator be installed at the same time? What should I pay attention to?
This is entirely possible. All of them are mixed installation, and a water mixing device (premixing center) is needed. The purpose of the device is to reduce the water temperature of the radiator with the required water supply temperature of 80℃ to the floor heating pipe with 60℃ without affecting the simultaneous heating of the two.
