Anonymous users2024-01-24[Phenomenon] room temperature 13-15 degrees, not up to standard, heating standard 18 degrees. The temperature of the radiator is about 40 degrees Celsius.
Reason] The water temperature is not enough for radiator heating, and the difference between water temperature and room temperature is about 50 degrees (the standard is degree and 50 degrees). In addition, it is the top floor, which is not heated (empty), and the heating environment is relatively bad, and the heat needs to be transmitted to the unheated home and the top floor, which will worsen the heating effect.
Solution] 1. Increase the water temperature. At present, according to the estimation of outdoor -5 degrees and indoor 13 degrees, the temperature difference is 18 degrees, the difference between water temperature and room temperature is 27 degrees, to reach 18 degrees indoors, the heat load needs to be increased by 27%, and the radiator temperature should reach about 53 degrees.
The addition of a circulating pump can speed up the flow rate of hot water and increase the water temperature.
2. If the water temperature cannot be raised, add radiators. Considering that the return water temperature drops after adding radiators, it is necessary to increase the number of radiators by about 50%.
3. Change floor heating. Underfloor heating is short for low-temperature radiant floor heating. The water temperature of 40 degrees is just right for underfloor heating, just like the 5th floor. According to his coil density, your house is on the top floor, up to about 21 degrees.

Anonymous users2024-01-231: The water temperature in the radiator needs to be about 70 degrees or above to reach the ideal temperature, and the water temperature of more than 40 degrees for floor heating can reach the ideal temperature. Judging from the data you gave, the water temperature given by the central heating is not enough. You can change it to underfloor heating.
2: The central heating on the 5th floor is changed to floor heating, and it is possible to use a mixed water center to convert the theoretically possible high-temperature water into low-temperature floor heating water. And the water resistance of floor heating is greater than that of heating, and the heat dissipation of floor heating on the 5th floor is also the highest in the same unit. It has a big impact on your home.
Three: It may be the central heating method of the upper and lower back, your home is the back, and the water temperature is lower than that downstairs is normal.
Four: The number of radiators may be less.
It is recommended to change the underfloor heating, which can solve the problem of your home.

Anonymous users2024-01-22First, look at the number of radiators in your home (I mean by the number of heating sheets).
Second, if there are few residents living upstairs, it will also have an impact on the heating.
Third, whether it is due to personal reasons, saving money and using less.
There must be a partition in between.
How to calculate bai for balconies
The construction area, whether the building area of the first floor includes the balcony, the canopy, and the eaves, and how to calculate the specialty? >>>More
"Code for Calculation of Construction Area of Construction Projects" GBT 50353-2013 stipulates: >>>More
Rest assured, there will be no problem, but you should pay attention to when laying bricks, don't let workers sprinkle too much water on the ground, which will soak downstairs, my living room is 38 square meters, I use all floor tiles.
The building code stipulates that: 1. The balcony in the main structure shall be calculated according to the horizontal area of the outer periphery of the structure; 2. The balcony outside the main structure should be calculated according to the horizontal projection area of the structural bottom plate 1 2 area; 3. The terrace is not counted as the construction area. The balcony is a space for residents to carry out outdoor activities, dry clothes, etc.
