How to make a warm floor from heating in an apartment

Heating

Warm floors in recent times enjoy unprecedented demand, thanks to technology that allows to obtain the maximum thermal effect. In addition, it is connected with the unsatisfactory work of central heating, which does not allow many tenants to feel comfortable in the cold season. The use of a durable, reliable, productive and inexpensive heating system in an apartment or house allows you to heat any room.

Warm water floor from the central heating in the apartment allows you to create a comfortable living environment.

In this case, it is not necessary to additionally install separate elements such as radiators. You will need a metal-plastic pipe, valves and control valves, as well as a cabinet where all this can be mounted.

We connect the system to central heating

Consider the option of "warm floor", where the coolant is water. The system can be powered from an autonomous heating circuit or from a central riser in the apartment. The second option is most often used, since individual heating of housing in an apartment building is still rare.

After connecting, you can achieve the highest level of performance and heat transfer, reducing the associated costs by almost an order of magnitude. We will tell you how to approach the process in such a way as to carry out the preparatory and installation work in the shortest possible time.

What to look for at the beginning

Before organizing a warm water floor from central heating, be sure to consider the following factors:

Circuit As a contour in the apartment traditionally use modern metal-plastic pipes that can withstand temperatures up to 95? С. This will allow it to withstand the pressure of the coolant and hydraulic shocks. The installation is carried out on the ground, adhering to a certain configuration scheme and closed with a cement screed. On the surface there are only bends for connection to the central heating system.
Working temperature Although usually the batteries in the apartment receive a coolant in the range of up to 65? C, in some cases, its temperature rises to 90? C. At the same time, the warm floor functions normally and at 35-40? C. Therefore, in such a system, it is necessary to install an additional heat point. The main body is a circulation pump, which provides fast and efficient circulation of the coolant, making it possible to reduce its initial temperature.
Collector cabinet We recommend that before starting the process to find a place to install a collector cabinet. It will need to place pipes, valves and drainage bends. The domestic construction market offers a fairly large range of cabinets, so before buying, decide on its dimensions and basic parameters.

Advice: coordinate the alteration of the heating system with specialized bodies, as a water-heated floor will create an additional load on the central heating system. Perhaps utilities will require the installation of a heat meter.

Contour configuration

To connect, you can choose the following method:

  • snake (meander);
  • helix (bifilar);
  • double zigzag;
  • spiral with offset center.

Each option has its pros and cons, so we recommend making a choice, taking into account your own preferences, taking into account some factors. For example, near the external walls, window and door openings, the heat carrier should be with a higher temperature.

Advice: it is impossible to determine the pipe laying pattern, then stop at the “snake” - a universal variant that is able to provide optimal heat transfer, as well as eliminate breakages and other troubles.

Installation

Below will be given the instructions for installation, which will be described in detail about all the nuances of the process.

It consists of several stages, with particular features of execution, which are recommended to pay attention to:

  1. Do the preparatory work. For this, clean the base with your own hands so that when laying pipes on it, there would be no problems. We recommend dividing the area of ​​the room where the floor heating system will be applied into small areas. In the future, this will provide an opportunity to increase the efficiency of work by reducing the time costs. Do not forget to lay the insulation material, which will help reduce heat loss, eliminating inefficient financial costs.

Tip: when laying insulation it is necessary to glue the edges of materials with a special rant tape. This will eliminate their shift during the process and simplify the work.

We prepare the base with the installation of heat insulators
  1. Install a mesh backing from thin reinforcement. The design will significantly increase the coefficient of rigidity of the pipeline, ensuring compliance with one level of pipe laying. In this way, you can ensure optimal circulation of the coolant.
  1. Install the pipeline by placing the pipes (O16-20 mm) according to a prearranged scheme. At this stage, the installation of the system regulator is carried out, with the help of which it will be possible to control the temperature of the floor. Install the pipes according to a specific step.

In each room, the value will be different. For example, in the bathroom - 100 mm, in the bedroom and kitchen - 200 mm, in the hall - 300 mm. Ensure that the total length of the contour does not exceed 50 m.

Spread compensation elements along the line of the room. Thereby it is possible to significantly reduce heat loss during operation of the heating. Do not forget to check the system for tightness.

  1. Install the controller that controls the operating temperature of the heat carrier and the collector cabinet. This step is an important point, because the quality and efficiency of the entire circuit depends on these devices.

Tip: install at the entrance to the pipeline system shut-off valves, then you can disconnect the warm floor at any time.

Connection of a water heated floor to a distribution manifold
  1. Make a pressure test of the heating system. Connect the circuit to the heating before you close it with a concrete tie. In this case, it is possible to reduce the load of the solution on the pipes, to avoid damage and their failure.

In a city apartment, the cost of a mistake can be too high. Due to the breakthrough of a pipe in an unsealed joint, neighbors will be flooded from below.

We recommend not to connect to the central heating before you receive the appropriate permissions from the regulatory authorities. In addition, it is necessary to invite their representatives when inserting into the riser of the central heating station and the first launch.

  1. Pour in the screed, for which use a conventional mortar based on sand and cement. Make a flat floor surface. All connections for supply, removal of coolant, as well as for monitoring its temperature, pre-bring to the surface.

Tip: you can use as a solution peskbeton M-300. It has the most optimum ratio of cost and quality, besides its thermal conductivity and operational features make it possible to obtain a productive and efficient heating system.

  1. Lay the floor covering. Be sure to wait at least 48 hours before installation so that the concrete can acquire its qualities. Floor coverings can be different - laminate, ceramic tile, linoleum, parquet.
  1. The last step is to start and test the installed heating system. We recommend to invite representatives of public utilities who can quickly in the event of defects block the flow of coolant.

Installing a water heated floor in an apartment from central heating for heating different rooms of an apartment is a fairly simple process that does not require special skills. Installation and connection takes very little time.

Of the advantages can be noted savings in heating, as it does not require high temperature coolant. In addition, the heat distributed from below allows you to create a comfortable and cozy atmosphere in the apartment.

Conclusion

You can make a warm floor today in almost every apartment of an apartment building. The only limitation is the working pressure in the central heating system and the volume of the coolant. In addition, the alteration of heating should in no way affect the efficiency of heat supply to other apartments in the house.

Therefore, before installation, you need to apply for permission to the utilities. The video in the article will help you find additional information on this topic.
