How to lay a warm floor under linoleum?
If you do not know how to properly lay a film underfloor heating under linoleum, then we will provide a step-by-step procedure for laying the film on the prepared surface. This version of the electric heating system is most often used in the kitchen and in the corridor. This is due to the practicality of linoleum - it is easy to wash and, moreover, the cost of the material is cheaper than a laminate and a parquet board. So, will not lose time and provide readers with "my.electricianexp»Detailed instructions with a video example!
Is it possible to heat such a coating?
The first thing I would like to tell you about is whether it is possible to lay an electric floor heating under linoleum and what are the requirements for installation. The fact is that a film coating can release toxins that are harmful to the human body when heated. In addition, the material may shrink over time, as a result of which its appearance will deteriorate. Well, the last caveat - this coating option can be additionally insulated, as a result of which the heating system will be completely ineffective. As you can see, there are nuances in choosing a suitable linoleum and now we will tell you which type is suitable for laying an electric warm floor.
Firstly, there are natural and artificial materials. It is advisable to give preference to the first option, because in this case, harmful substances will not be released during heating. Secondly, manufacturers indicate on the packaging the suitability / unsuitability of using products for the electric underfloor heating system. You understand that you need to choose products with the appropriate labeling. Well, and thirdly, the multilayer PVC linoleum, which we recommend buying with our own hands for the installation of a film warm floor, has proven itself best in reliability, strength and heat transfer.
Another important nuance is that there is a maximum permitted linoleum heating temperature. Electric underfloor heating should not heat more than 30aboutC, which is negotiated even by the rules of SNiP. If you ignore this moment, the material may begin to melt, darkened traces will appear and, in addition, the probability of ignition of the coating will increase.
What type of heater is better to use
We have already considered types of electric underfloor heating, which can be represented by a thermo gun, infrared film or heating cable. All three options are suitable for laying the heating system, but it is best to use an infrared film coating.
This is due to the following advantages of the material:
- During installation, you can do without screed, which will save time, money and most importantly - the ceiling height.
- Putting the infrared system into operation can be carried out within 1-2 days after installation. At the same time, the screed freezes for about 4 weeks.
- Film underfloor heating under linoleum is easily mounted with your own hands, and you can do this even after a major overhaul, as this type of work is “clean”.
As you can see, the advantage of this version of the system speaks for itself, therefore we recommend using it at home. The only negative is that the infrared coating is afraid of water, so it is forbidden to lay it in wet rooms. In addition, linoleum itself begins to rot in a humid environment, which immediately cuts off its use in the bathroom, bath, damp rooms.
So, to your attention, the procedure for laying a film warm floor under linoleum with your own hands:
- Make heating system calculationto correctly select the power of the infrared film and its size in accordance with the useful area of the room.
- Prepare the surface - remove the old coating and if the floor is uneven, fill in a small screed to level the surface.
- After the solution has solidified (which may not be necessary), lay a heat-insulating material over the entire surface. It is best to use extruded polystyrene foam.
- Glue a heat-reflecting layer on top of polystyrene, which will increase the efficiency of the system. You can "kill two birds with one stone" by covering the surface with penofol (shown in the photo), which is both a heat-insulating and heat-reflecting layer.
- Cut the film into suitable pieces. This should be done in specially marked places (indicated by the manufacturer).
- Install the infrared warm floor under the linoleum. Please note that overlapping film is prohibited. Another requirement - under the furniture you can not lay the material. Also do not forget that the film coating should be laid at a distance of at least 30 cm from other types of heaters, so that the system does not overheat. About the remaining requirements for laying of a film heat-insulated floor can find out in the corresponding article!
- According to the scheme, connect the temperature controller and temperature sensor to the film and check the system’s operability by connecting it to the mains.
- If everything is correct, spread a layer of plywood on top of the film coating, which will additionally protect the material from mechanical damage.
- On plywood, lay linoleum over the entire area of the room with the heating turned on. After that, make a cut and leave everything as it is for 2-3 days. When this period passes, you can cut the edges again (if necessary) and proceed to gluing the material to the plywood.
- Set the thermostat to a setting of no more than 30 degrees, on which the installation of the film underfloor heating under the linoleum is completed!
We also recommend that you watch the step-by-step video installation instructions for the infrared film, which details all the stages of work:
That's the whole procedure for laying a film of warm floor under linoleum with your own hands! As you can see, there is nothing complicated and you can do everything yourself without calling the wizard. In conclusion, I would like to once again note that an infrared heater is still better than an electric one (heating cable and thermomat), so use this installation technology in your home!
