1, houses with indoor clear height less than 2.6m
The floor heating is buried underground, so there are requirements for the height of the house. In the circulating system, the wet floor is heated and molded to occupy the floor height of 8 cm-10 cm; Dry floor heating molding occupies a floor height of 5 cm-6 cm; The molding height of electric floor heating is 5 cm-6 cm; Carbon crystal floor heating molding occupies a height of 5cm-6cm.
Including the height of paving materials, the impact on high-rise residential buildings is not particularly great, but for residential buildings (old houses, affordable houses, etc.) ) If the height is less than 2.6m, the installation of floor heating will make the clear height of the room too low, and people will feel depressed when living.
2. Renovated house
Floor heating is to bury the floor heating coil under the floor or floor tile. For a room that has been decorated, if you want to install floor heating, you will destroy the original floor decoration, which will not only waste time, but also generate additional expenses. If you want to install heating to make winter more comfortable, you can choose to install radiators.
3. The lower edge of the entrance door is less than 10cm from the ground.
The floor heating installation has a certain thickness, so the distance from the lower edge of the door leaf to the ground of the entrance door (the outer door is not affected) should be greater than or equal to 10cm, otherwise the normal opening of the door will be affected after the floor heating installation.
4. Single central heating pipe connected in series
For old buildings with central heating, whether it is suitable to install floor heating mainly depends on whether the pipes are connected in series or in parallel. Users with single pipe in series cannot install floor heating. The judgment method is that there is a riser in every room in the house, and then a group of radiators are connected from the top floor to the next floor. In this case, if the floor heating system is installed, it will not only be difficult to reach the ideal temperature level, but also affect the normal heating of the neighbors downstairs.
5, pipe hard connection
There are two ways to connect pipes: hard connection and soft connection. Generally, galvanized pipe is used for hard connection, which has poor flexibility and must be adjusted by special pipe bender, which weakens the pressure-bearing capacity of the pipe and is not suitable for floor heating.
The above is the introduction of five situations that are not suitable for laying floor heating, but some problems are not absolute. With the development of technology, some problems can be skillfully solved by means of floor heating design and construction. If you can't choose floor heating, you can also choose to install a radiator. Now radiator technology is more and more developed, which can not only keep warm, but also dry clothes. The appearance is simple and generous, and it also plays a very good decorative role at home.
