Warm floors are easy and simple in a wooden house on wooden logs - Instruction + Video Warm floors are now one of the most commonly used ways to create heating in a private house, since it can act as independent heating, even in a wooden house, and will save you from bulky heating radiators.

Types of heated floors

  1. Water;
  2. Electric, which, depending on the type of heating element are divided into:
  • film;
  • rod;
  • cable.

According to the heating method, electrical systems are divided into:

  • convection;
  • infrared.

Creation of warm floors in the house significantly reduces heating costs, since you can turn on each heating circuit separately. Thus, you can simply disconnect unused rooms from heating.

The principle of operation of the water floor scheme

In a private house, a pipeline is laid under the floor in a parallel or spiral laying pattern. Water circulates through the tubes, which transfers and evenly distributes heat to the material laid near them. All this heats the floor. The choice of heat transfer material depends on the construction of the floor.

Types of floors:

  • wooden floors;
  • polystyrene;
  • concrete.

In private and country houses, concrete structures are often used, sometimes hollow wooden floors.

Installation work plan

Before installing the underfloor heating, you need to draw a plan - a grid that will reflect the entire heating system. When drawing on the project plan for laying water pipes and planning the layout of the heating circuit, it is necessary to take into account that:

  • there should be a distance of 0.2 - 0.25 m between the pipes and the wall;
  • the interval of the annular gap - 0.

    35 - 0.5 m;

  • the pipe extending from the riser is laid along the window;
  • the density of pipes increases at the outer walls, and decreases towards the center of the room. For example, the distance between the pipes at the door, windows and external walls is 0.15 m, on the rest of the area - 0.3 m;
  • in any case, during installation, observe a step of 0.

    1 m;

  • the distance from the contour to the outer wall should not be more than 0.15 m;
  • the length of the heating loops should be no more than 100 m.

According to the drawn drawing you you can calculate the required number of pipes. Please note that to bring them to the collector, you will need about another 2 m.

When choosing the diameter of the hose, consult a heating engineer.

Do not forget that thermal fluids do not need to be placed under furniture. Think about this moment in advance.

Materials used for installation

To install a warm water floor in a country house, you will need:

  1. insulation material (expanded polystyrene plates, aluminum foil;
  2. pipe for hot water heating;
  3. damper tape;
  4. dense polyethylene and corrugated pipe;
  5. reinforcing mesh;
  6. cement - sand mortar or dry composition of "self-leveling floor";
  7. beacons, fasteners, dowels, screws.

How to install a warm concrete water type floors

Given the complex design of this system, it is important that the house has high ceilings, since the arrangement of a warm floor will eat up their height by at least 8.5 cm.

Layer-by-layer diagram of a water concrete warm floor from bottom to top:

  • rough floor;
  • heat insulator;
  • mesh for reinforcement;
  • concrete with heating circuit;
  • substrate made of cardboard, polyethylene or plywood;
  • decorative cladding.

Device stages:

Preparation:

  • The first thing to do is to prepare the surface and level the base. Often in a country house they use a cement-sand screed, checking the horizontal level on the lighthouses. You can use the now common self-leveling mixtures for warm floors.
  • After that, we carry out waterproofing work, laying strips of dense polyethylene or aluminum foil.

  • We fix the damping tape with self-tapping screws around the perimeter of the premises 2 cm above the screed, which will ease the load during linear deformation.
  • We put a layer of thermal insulation on the water heater. For this we use mineral wool, expanded polystyrene plates, polystyrene, foam concrete, cork. The thickness of the heat insulator depends on the capacity of the heating system. It is better to use special material for arranging warm floors.

  • On top of the heat insulator, we lay a reinforcing assembly mesh that fixes the pipes with the coolant and reinforcing the concrete screed.

Installation of the floor heating circuit diagram

The pipes are attached to the installation grid with plastic clamps according to the selected scheme. The ideal distance between fasteners is 0.3 - 0.4 m.

Installing the collector and connecting the heating circuits:
  • The collector is mounted in a special niche above the floor in the center rooms on the wall. Typical dimensions of the collector cabinets are 0.6 x 0.4 x 0.12 m.

  • We put the supply pipe from the boiler and the return hose into the niche. We put shut-off valves. We connect the collector and plug its end. You can install a splitter, for which we screw in a drain valve at one end, and an air vent at the other. So you can disconnect unnecessary rooms from heating.

  • At the point where the pipes exit from the screed, we protect them with special corners or a corrugated tube. We cut the pipe, put on a collapsible fitting and connect it to the collector with a union nut.

Balancing the collector

Water floor heating circuits often have different lengths. Therefore, the coolant must be selected with an individual pressure. To do this, remove the protective caps on the manifold and adjust the working pressure.

Testing underfloor heating

Before pouring the concrete screed, check the system for leaks. This can be done using a compressor and compressed air.

If everything is working properly - start pouring the concrete screed. For this, the water floor must remain under pressure.

Pouring concrete screed

On top of the system, we lay a concrete, cement - sand screed or a mixture of a self-leveling floor, and align with the lighthouses with a long rule.

Minimum screed thickness 5 cm.

When the mixture has hardened, check its tightness again before laying.
