A pipe with a diameter of 10 mm and a pitch of 10 cm - is this option of a warm floor possible?
This winter I tested my heating under the “warm floor” type at home. The design was with a water pipe in the screed. When the device was implemented, a scheme was introduced: a pipe with an internal diameter of 16 mm, laid in increments of 30 cm. First impressions are as follows - I would like more heat. Winter was just cold; there wasn’t enough warm floor; I had to include additional oil batteries in the children's room. And on the floor, differences between the pipes were clearly visible. I saw a plot on TV where a company was shown at an exhibition in China that produces pipes for underfloor heating with a diameter of 10 or 8 mm (I don’t remember). The essence of the idea is that the laying of pipes of a water heated floor is performed more often. Thus, it is possible to avoid the creation of heat-cold zones. And the heating system itself will be more efficient. This winter I “accelerated” the temperature to 55 degrees in order to maintain a good normal temperature in the house. I am interested in the opinion of our specialist regarding thin tubes. I plan to make such a floor in the new office.
Hello! In our opinion, a thin pipe laid in increments of 10 cm will be useful in a warm floor system only with a “fatal” limitation of the thickness of the floor cake. Warm floors have long found their practical embodiment in various systems and have been tested in practice. Based on experience, we can safely say that a pipe with an outer diameter of 16-17 mm, mounted in increments of 15-20 cm, gives an excellent result. At the same time, the thickness of the screed should be equal to 6-8 mm.
By the way! The difference between the step size of 10 cm and 15 cm is not more than 15%. Therefore, it is not necessary to talk about the colossal heat transfer of a floor with a thin pipe.
Moreover, it is necessary to take into account the fact that thin tubes are characterized by disgusting hydraulic parameters. This means that the loops will have to be made short, which means there will be additional costs for the purchase of collectors and cabinets.
One way or another, on which version of a water heated floor you would not stop your choice, use a pipe that is specifically designed for the “warm floor” system. Only in this case, it can be hoped that when laying the pipeline it will bend and not break.
