One of the conditions for the implementation of high-quality and proper heating of the room with a warm floor is to maintain the temperature of the coolant in accordance with the specified parameters.
These parameters are defined by the project, taking into account the required amount of heat for heated premises and flooring.
Required data for calculation
The efficiency of the heating system depends on the correct loop
To maintain a given temperature regime in the room, it is necessary to correctly calculate the loop length used to circulate the coolant.
First, it is necessary to collect initial data, on the basis of which the calculation will be completed and which consist of the following indicators and characteristics:
- temperature that should be over the floor coating;
- layout diagram loops with heat carrier;
- Distance between pipes;
- the maximum possible length of the pipe;
- the ability to use several different in length of contours;
- Connecting several loops to one collector and to one pump and the possible amount of them with such a connection.
Based on the listed data, it is possible to correctly calculate the length of the circuit of the heap floor and, due to this, ensure comfortable temperature regime in the room with minimal costs of energy supply.
Paul temperature
The temperature on the floor surface made with the device under it is water heating depends on the functional purpose of the room. Its values must be no more specified in the table:| № | Water warm facilities | Temperature on the floor surface |
|---|---|---|
| one | Premises of the most frequent stay of people (bedrooms, living rooms, cabinets, kitchens, children's, game, etc.) | + 29s |
| 2. | Bathrooms and bathrooms | + 33s |
| 3. | Bordering with them the premises (corridors, hallways, verandas, storage rooms, etc.) | + 35s |

Compliance with the temperature regime according to the above values will allow you to create a favorable environment for the work and recreation of people in them.
Pipe laying options used for a warm floor
Warm floor laying options
The laying scheme can be made by the usual, double and angular snake or snail. Various combinations of these options are also possible, for example, on the edge of the room you can post a snake pipe, and then the middle part is snail.
In large rooms of a complex configuration, it is better to perform snail laying. In the premises of small sizes and having a variety of complex configurations apply styling a snake.
Distance between pipes
The pitch laying step is determined by the calculation and usually corresponds to 15, 20 and 25 cm, but not more. When laying a pipe with a step of more than 25 cm, a person's foot will feel the difference in temperatures between and directly above them.
At the edges of the room, the pipe of the heating circuit is laid in 10 cm increments.
Permissible length contour
The length of the contour must be chosen under the diameter of the pipe
It depends on the pressure in a specific closed loop and hydraulic resistance, the values of which determine the diameter of the pipes and the volume of the fluid, which is supplied to them per unit of time.
When a warm floor device often occur, situations occur when the circulation of the coolant in a separate loop is disturbed, to restore which is not possible by any pump, the water is locked in this circuit, as a result of which it cools. This leads pressure losses up to 0.2 bar.
Based on practical experience, you can adhere to the following recommended sizes:
- Lending less than 100 m can be loop, made of metal-plastic pipe with a diameter of 16 mm. For reliability, the optimal size is 80 m.
- Not more than 120 m take the maximum length of the contour from 18 mm pipe made of stitched polyethylene. Specialists try to install an outline with a length of 80-100 m.
- Not more than 120-125 m is considered permissible loop size for metal-plastic with a diameter of 20 mm. In practice, it is also trying to reduce this length to ensure sufficient reliability of the system.
To more accurately determine the size of the loop length for a warm floor in the indoors under consideration, in which there will be no problems with the circulation of the coolant, the calculations must be performed.
Application of several contours of different lengths
The device of the floor heating system provides for multiple contours. Of course, the ideal is the option when all the loops have the same length. In this case, it is not necessary to configure and balancing the system, but it is almost impossible to carry out such pipe laying scheme. Detailed video on the calculation of the length of the water circuit, see this video:Article on the topic: How to separate a brick house inside: design ideas
For example, you need to perform a warm floor system in several rooms, one of which, for example, the bathroom has an area of 4 m2. So, it will take 40 m pipes. It is impractical in other rooms of the contours of 40 m in other rooms, while you can perform a loop of 80-100 m.
The difference in the length of the pipes is determined by the calculation. If it is impossible to perform calculations, you can apply the requirement that allows a difference in the length of the circuits of about 30-40%.
Also, the loop length difference can be compensated by an increase or decrease in the pipe diameter and changes in its laying.
Ability to connect to one node and pump
The number of loops that can be connected to one collector and one pump is determined depending on the power of the equipment used, the number of thermal contours, the diameter and the material of the pipes used, the area of heated premises, the material of the enclosing structures and from many other different indicators.
Such calculations must be entrusted to specialists who have knowledge and practical skills in the implementation of such projects.
Determination of the size of the loop
The size of the loop depends on the total area of the room
Having collected all the initial data, having considered the possible options for creating a heated floor and determining the most optimal one, it can be proceed directly to the calculation of the length of the water heating floor circuit.
To do this, it is necessary to divide the area of the room in which the loops for water heating of the floor are stacked for the distance between the pipes and multiply to the coefficient 1.1, which takes into account 10% for turns and bend.
The result must be added to the length of the pipeline, which will need to be paved from the collector to the warm floor and back. The answer to key questions of the organization of a warm floor, see this video:
To determine the length of the loop stacked with a step of 20 cm in an area of 10 m2, located at a distance of 3 m from the collector, by following the following steps:

10 / 0.2 * 1,1 + (3 * 2) = 61 m.
In this room, you need to lay 61 M pipes forming a heat outline to ensure the possibility of high-quality heating of the floor covering.
The presented calculation helps to create conditions for maintaining a comfortable air temperature in small separate rooms.
To properly determine the length of the pipe of several thermal contours for a large number of rooms powered from one collector, it is necessary to attract a design organization.
It will do it with the help of specialized programs that take into account many different factors on which the uninterrupted circulation of water depends, and therefore high-quality heating of the floor.
