In most situations as the insulation material used foam or other suitable material.

also commercially available heaters designed specifically for installation in combination with underfloor heating pipes.In their structure already present channels for laying pipes.

fifth step

Lay insulation over the reinforcing mesh.It will contribute to an increase in the strength of ties, which you will fill the pipe.

recommendations on the selection and installation of pipes

scheme installation of water floor heating

you need to perform an individual calculation and to determine the optimal parameters of laying pipes for each individual room.

calculation is easiest done using a specialized program - it will give you the opportunity to save time and effort.

To calculate the required power for each individual circuit solely by the formulas is hard enough.This calculation requires the consideration of multiple parameters.At the same time the slightest mistake can lead to very adverse consequences.

Calculation of underfloor heating systems

Calculation of underfloor heating systems

To perform payment system you need to know the following parameters:

  • size heated room;
  • material manufacturing floors, walls and load-bearing walls;
  • features insulation under the floor heating system;
  • kind of finish flooring;
  • diameter pipes used for arrangement of floor heating systems, as well as material for their manufacture;
  • power of the heating boiler.

These options allow you to calculate the optimal length of the stacked pipes, as well as the appropriate step of their placement to ensure the necessary level of heat transfer.

Also, you should choose a suitable route of laying pipes.Remember, when passing through the pipes the water gradually loses heat.Therefore distribution system elements need to perform, taking into account some important nuances , namely:

  • pipe is recommended to start to lay off at least warm (outer) walls of the room;
  • if the pipe is introduced into the room is not on the part of the outer wall, the part of the pipe from the injection point to the need to insulate the wall;
  • to gradually reduce the intensity of the heat from the external walls of the room to the internal use version stacking "snake";
  • to ensure uniform heating in the room space without external walls (wardrobes, bathroom, etc.) To be used in a spiral mounting method.This spiral must be developed from the edge of space in the middle of it.

most commonly used step of laying pipes floor heating - 300 mm.In areas with increased losses of heat pipes placing step can be reduced to 150 mm.

Additionally, you need to calculate this figure as the flow resistance of the pipe.This value increases with an increase in parallel and the length of each loop bend.

desirable that the resistance tube in circuits connected to a common manifold, was identical.To do this, divide especially large outlines of several smaller circuits.It is especially great in this case are the contours of the pipe length exceeds 100 m.

Also, experts strongly recommend not to heat several rooms with one loop.The attic floor, verandas, balconies, etc.the room should be heated separate loop system.Otherwise, the heating efficiency will decrease significantly.

Installation flooring system with heated

attempting to install the system.Work is carried out in several stages.

first stage - collector

Wiring of the water floor heating

Wiring water underfloor heating

Installation of the collector is performed in specially designed for this collector box.Typically the thickness of such a box is 120 mm.Dimensions are selected according to the size of the collecting rude and considering the size of various kinds of sensors such as sinks additions, pressure, etc.

Collector : appearance and scheme of work

equip collector group so that there is a gap under it, enough to bend pipes.

Install collector cabinet.Make it so that the performance of each length of pipe from the heated space and system circuit are approximately equal.

The main elements of the collector node

The main elements of the collector node

The most common manifold cabinets are simply mounted on the wall - 120-mm thickness allows it.The collector box should be installed above the level of the floor heating system.

is important to keep in mind: to create all sorts of niches is not recommended in the supporting walls, and in most cases even strictly prohibited.

Assembling the collector cabinet is performed in accordance with the instructions supplied, so no problems and difficulties at this stage you will not have.

second stage - heating boiler

First, select a suitable power boiler.The equipment must normally carry incoming load and have some headroom.The calculation is simple: you add up all the capacity of floor system heating and add a 15 per cent margin.

Boiler equipment

Boilers

circulation of the coolant pump is provided in the system.The construction of modern boilers includes in its membership the right pump initially.Usually it is enough power to ensure the proper functioning of the system in the premises of an area of ​​120-150 m2.

In the case of if the room dimensions exceed the above values, you have to install an additional pump.In such situations, the pumps are installed in remote cabinets collector.

Boiler equipment

Boilers

on-site input and output coolant from the boiler must be shut-off valve.With these devices you can turn off the heating equipment with the appearance of such a need, for example, for repair or preventative maintenance.

The most common domestic masters prefer electric heating boilers - they are the most easy to install and very well show themselves when working in conjunction with the underfloor heating system.To install and connect the equipment quite simply follow the provisions of the manufacturer's instructions.

third stage - pipes

Pipe laying is performed in accordance with a pre-prepared scheme.For fixing elements are commonly used profiles with holes to accommodate screws.

You can also attach the pipe to the mesh using plastic cable ties - this has already been mentioned earlier.

Panels can be joined by laying their lap , holding a number of projections

panels can be connected by laying their lap, holding a number of projections

When attaching pipes, make sure that they are not clamped too tightly - it is better when the loop is free.

Bends try to make the most accurate, respecting, at the same time, recommendations on the minimum allowable radius.In the case of plastic pipes the range usually 5 pipe diameters.

Connecting pipes

Connecting pipes

If you are too hard polyethylene pipe too hard on her bending strip formed whitish hue.This indicates a crease occurs.Use these tubes is prohibited - quickly break appears at the crease.

pipe system Connecting to the collector are made using the same fitting or evrokonusnoy system.

After the installation of the system is required to check the warm floor.To check the fill water, apply pressure of about 5 bar and leave the warm floor in this state for a day.If after 24 hours will not be observed any significant extensions and leaks can begin to tie arrangement.

fourth stage - screed

strainer

Screed

When pouring concrete ties to the pipes must be filed with the operating pressure.After pouring the screed must be left to dry for a month.Only after a complete set of tie strength can proceed to the installation finish.

When forming concrete screed must take into account a number of important features related to the heat distribution in the interior of the character of the fill and apply the finish coat.

If the tile is laid, the screed thickness should be about 30-50 mm.Or you can reduce the distance between the pipes of 100-150 mm.Otherwise, the heat will be distributed completely evenly.

When laying linoleum, laminate panels and so forth. Screed thickness should be even smaller.For hardening pouring in such a situation it is necessary to use an additional reinforcing mesh is laid over the pipes.

Screed

thus laying the floor heating system runs on its own without any problems.We just need to follow the instructions given to the provisions and responsible approach to the implementation of all activities.
