Choosing an energy source for a warm floor system, many housing owners prefer water heating due to its economy and reliability. Installation of water heating as an additional or main source of heat - the process is not complicated.
The main node of the design of the heating is a comb for a warm floor that is responsible for performing several basic functions.
We'll figure it out in the functionality of the node and the specifics of the work.
Functions comb
Choosing the heating system as a heat source, acting on the circulation of water in the pipes, it is worth considering the specifics of such a system, estimating the following factors:
- The complexity of water distribution by pipes;
- necessary volume to fill the system;
- finish coating;
- Required energy temperature.
Greeting device
If the warm floors perform the function of additional heating, the size of the pipes in the floor will be much smaller than that of the main heating system.
The water temperature in the circuit should not exceed 55 degrees
Therefore, it is important to understand that the water should meet certain requirements at the entrance:
- The maximum allowable temperature is 55 ° C. In the batteries of the main heating system, this standard is much higher, there should be no less than 650c.
- Uniformly and with the same pressure is distributed through pipes.
- Timely outflow of the cooled carrier from the contour pipes.
It is these tasks that performs a warm floor comb: the thermostatic mixer connects 2 water flow, achieving the desired temperature value at the inlet, preventing sudden pressure drops in the pipes and controlling the removal of cooled water from the system.
Elements of the distribution and control node
To perform the above functions in the grade wall structure for a warm floor included:| № | Element comb | Function performed |
|---|---|---|
| one | 2 collectors with adapters for input and output | Energy distribution and output |
| 2. | Crane for air shutter | When starting the system, for air and filling the pipes with water |
| 3. | water drainage | For the possibility of draining water for repair work |
| four | Check valve | Blocking hot-energy outflow |
| five | pump | Provides a constant circulation of water inside the system, controls the flow rate |
| 6. | Power faucet with a temperature sensor | Adjusting the volume of incoming water |
| 7. | Thermal valves at the exit | When cooled water to a given level, the valve opens onto the outflow |
| eight | Input flow counters | System control |

Principle of operation of the mechanism
It is very simplistic to describe how a comb dryer works for a warm floor, this is possible: a node of the input-output with the control of the feed rate, pressure, volume and temperature of the energy carrier.
Phased water movement in the system of comfortable water floors:
- From the boiler or from the central heating system, water enters the element of the feed valve of the comb whit for the warm floor. Here there is a mixing of cold and hot water, the height of the flap is adjusted;
- Under the influence of the pump, water moves into the feed collector. Due to the difference in the lengths of the contours, the number of water supplied in them is also different. Flow meters are installed on the nozzles. If at this stage to use in the servo drive process connected to the temperature sensor, then you can automate the water supply process when the floor is cooled below the specified temperature;
- When working out, the water is displayed from the system through the output manifold. To control the level of pressure in the system, the valve is installed here, which must be operated automatically during an excessive value.
Selection and installation

If professional professionals are engaged in installation, then the easiest solution will entrust the installation of the distribution control node.
At the same time, if you independently conduct a water heating system, then collect the comb for a warm floor with your own hands will not be difficult. All components of elements can be purchased separately in any construction store.
By purchasing a comb from the factory producer, pay attention to the nodes included in the kit. Security elements must be embedded: safety valve and air descent valve. In case of unforeseen changes in the specified parameters, these items stabilize the operation of the system. For details on the mixing site, see this video:
Pay attention to the material of the main nodes. Do not buy combs of copper alloys, because they do not differ long service life.
Metal box will protect the comb from random changes of regulators

It is better to give preference to a stainless steel or PVC product.
There are some points that need to be taken into account when installing. The comb for the warm floor should be inside the metal box. This will prevent from random impacts and shifts of regulatory nodes.
In addition, thus, it is possible to decorately hide a rather non-welltic device. When installing, these recommendations should be followed:
- Place the comb is necessary at the highest possible point relative to the warm floor system. This will allow in an emergency to quickly get rid of air in the pipes.
- By mounting the comb, it is necessary to consider the length of the hose connection of each contour, their value must be approximately the same.
- The number of inputs and outputs on the ridge should be equal to the number of heating circuits. On how to mount the comb in a niche, see this video:
Do not configure the thermostat to the carrier temperature above 550c. The efficiency of the system will increase slightly, but the finish flooring will certainly deteriorate.
For the same reason, do not connect the heap pipes directly to the central heating system.
A mounted comb for warm sex will avoid excess heating costs, guarantees a comfortable level of floor heating, and in the event of an accident - a quick solution to the issue of water outflow without any changes in the indoor internal climate.
