The minimum distance between national standard floor heating coils is 100mm. But the maximum can not exceed 300mm, the spacing is too small, the coil is difficult to cause poor construction, and the spacing is too large to meet the heat dissipation requirements.
Home use is generally 25cm spacing, 20cn also works. Public places are generally 25-30cm apart. According to the different heating conditions and room layout, the space between the floor heating pipes is designed in the range of 100MM-300M. The general pipe spacing is about 200MM.
Standards for laying spacing between floor heating pipes
There are two kinds of floor heating pipes commonly used now. One is a pipe diameter of 16, and the other is a pipe diameter of 20. The distance between the two types of pipes is different, and the process of the pipe spacing is also very different in various aspects. For example, the pipe spacing in the general bathroom is between 10cm-12cm. And the living room and the like are between 20cm-25cm.
The spacing of floor heating coils is determined by a series of factors such as room heat load, supply and return water temperature and temperature difference, insulation layer and thickness, filling layer and thickness, decorative surface layer and thickness, etc. must be considered comprehensively. The layout of the coils should be adapted to the distribution of the heat load in the room. Where the heat load is large such as the outer wall, the coils should be relatively dense; while the central load in the room is small, the spacing between the coils should be larger. In this way, the indoor temperature can be uniform, the air convection can be reduced, the air quality can be improved, and the floor heating effect can be exerted.
Disadvantages of too close spacing between floor heating pipes
Many users think that the smaller the spacing between floor heating pipes, the better, but this is actually a wrong understanding. Density has the following disadvantages:
1. Increase investment
The pipeline is laid too densely, which increases the consumption of floor heating pipes and increases the initial investment of the owner, even if Dealers’ initiative to increase the density in the later stage does not affect the owner’s investment, and the disguised increase in cost and reduction of corporate profits may not be a good thing for the owner in the long run.
2. Affecting the service life of the wall-hung boiler
Excessive floor heating pipes will increase the resistance of the pipeline, making the circulating water pump of the wall-hung boiler at full load or even at full load. Work under overload conditions, thus affecting the service life of the wall-hung boiler.
3. Increase the risk of dead bends, increase water resistance, and reduce flow
Blindly narrowing the spacing of the floor heating pipes will cause the floor heating circuit to increase a lot of turns. At the same time, the thermal resistance will be increased; in addition, the construction difficulty will be increased, and the phenomenon of poor circulation or local overheating will often occur.
Therefore, the laying distance of the floor heating pipes should be determined according to the temperature of the water supply and the heat load of the room, which can not only ensure the heating requirements, but also prolong the service life of the floor heating and wall-hung boilers, so as to ensure the comfort of heating in winter.
