Mounting of warm floor water

 About the advantages of surface heating, we told you in the article '' Comparison of water heating systems. ''

Now we'll tell you how to properly install the water-warm floor.

Typically, the system of floor heating is installed in country houses, but at the moment is gaining popularity in its installation and in apartments. At the same time, if you want to make a warm floor in an apartment then you should start with approvals in the housing and utilities and get permission to perform this type of work.

Water heating systems are considered one of the most difficult to install.

Now you will understand why.

Start installation should not be from the procurement of materials and the design of the system. At least for yourself, on a notebook in a cell. First of all, you need to decide on the installation of the distribution comb. If the house has a boiler, then the comb is usually located below it. But this is not necessary. It is convenient when the collector is located in the middle of an apartment or house. It is then easier to balance the system to work properly.

Once you have determined the location of the pipe start, you can plan out the contours. It is estimated that one contour covers no more than 15 m2 of floor. That is, if we have one room with an area of ​​30 m2, then there will be two contours of warm floor in it. But small rooms, such as dressing rooms, corridors and bathrooms, do not necessarily have to have independent contours. Corridor and bathroom is beautifully covered with one branch.

With the number of contours figured out. The next point is the choice of the method of laying a warm floor pipe.

the simplest is a snake. In this variant, the feed is brought to the window and stuck in the direction towards the exit from the room. This option is convenient when the room has large windows or exits to the terrace. Part of the room with a lot of heat loss gets more heat. But you should know that in this option you may feel the unevenness of the warming up of the floor. At the window the floor will be warmer and at the door cooler. But in a well-insulated house, this difference is quite small, 2-4 degrees Celsius. Also, near the window, you can put trub more often in a step of 10 cm and closer to the door less often.

If you want uniform heating of the floor then the next option is stacking parallel snake. In this case, the laying of a tube with zigzag begins with the entrance to the room, but with a distance of 2 times greater than with a normal snake. When we get to the window then the back branch just closes the pass. But in this case, the unevenness of the warming can also be felt. After all, we get 2 feed lines and two reverse lines are in parallel. Also, the lower temperature outside the exterior walls is not taken into account.

We move on to the next, the most complex and most effective option. Laying a pipe with a snail. In such a solution, the feed goes from the outer walls to the middle and in parallel turns back. In this variant, we have a clear alternation of feed and return and maximally uniform warming of the room from the outside to the middle. But this is the most difficult option for stacking. Everything should be carefully marked and then started to be stacked. Note that it is desirable to rotate the pipe radius not less than 150 mm.

For the floor heating is usually chosen high quality polyethylene pipe designed for this type of work. The pipe consumption is approximately 50-100 m per 10 m2, depending on the step.

Now you can begin to calculate the materials.

We will need:

1. Heater We choose the thickness according to the goals. If the base was insulated earlier, then a sufficiently foil backing. And if from the bottom there are unheated premises it is necessary to insulate the insulation and take a minimum of 100 mm thick. If you want to make a house energy-efficient then think about 250 mm of high-quality thermal insulation. Indeed, in contrast to the walls in the floor to add insulation will be impossible.
   

2. Waterproofing film, polyethylene density 100-150 microns. Throughout the area of the floor + overlap 10 cm. And the building adhesive for sticking joints
   

    

3. Foiled lining for warm floor or mat.
   

4. 

5. reinforcing mesh 1-1,5 mm with a center of 50 mm in accordance with the floor area + flapA mixture of cement-sand for a tie of 90-110 kg / m2. Please note that for the whole apartment the weight of the coupler can reach 10 tons and it is not allowed to put it in one place.
   

6. Beacons for level reflection

7. Alabaster for the installation of beacons

8. The pipe for floor heating is 5-10 m per m2 depending on the step

9. Damper ribbon

10. Comb with thermostat and pump

Now a photo report of the installation process.

How to make a warm floor installation water:

• We clean the base from garbage and level the inequalities. Big performances are better to knock down, if there is a depression it is possible to make a small filling with sand or sucking and align with the trampling.
  

• Stack the required amount of heater
  

• Stack waterproofing film, gluing joints
  

• We harness the comb in the right place. We follow the level and keep the horizontality.
  

• Stack foil tape with markings for pipes or mats
  

• 

  On the contour of the rooms glue the damping tape, it is also possible to separate the contours from each other.

  We make a preliminary marking of the contours of the warm floor

   

Put a reinforcing mesh with a bang and tie it in one cloth

•   

  Unwind the pipe and fasten it to the grid in accordance with the plan. If put in a mother, fixation can be done less often. It is better to use plastic screws to avoid damaging the pipe.

  We watch that the pipe is not bent or broken. If the room is formed, the outline will need to be translated. You do not want to discover that at some point in the system began to go water.

  After laying the contour cut the pipe with a stock of 30-40 cm

   

• We make consistently all the contours
  

• 

  Fix the pipe fittings to the comb. We keep following the filing and returns.

  Fill the system with water and check the tightness. You can create a test pressure of 6 atm and leave it for a day to check leakage.

   

• After checking the system, you can go to the installation of beacons
  

• 

  Fill the screed from the walls and move to the center and exit the rooms

  The tension is ready. The system can be started in 28 days. When the cement hardens.

  Water warm floor price

• 
  Estimated cost of work on installation of floor heating 150 - 200 UAH / m2

  The cost of materials depends on the components and varies in the area of ​​300-400 UAH / m2

  The cost of work and materials for filling the bond - 250-300 UAH / m2

  It is also worth taking into account the cost of shipping and unloading materials.

  Spending time:

  - Planning, preparation, delivery of materials - 1 week

  - stacking of the heater, pipes, connection - 4 days

  - Filling the binding - 1-2 days

  - waiting for the system to start - 1 month
