Underfloor heating by their own hands : step by step instructions and installation

good feature heated floor with a liquid coolant is that it can be installed using the existing communications, such as the main heating system.

This space heating can be done as a combined, ie the simultaneous use of heating radiators and piping systems in the floor, and only with the use of only the piping system of the heated floor.

only, but very important thing to be considered when connecting the heated floor system to the main heating system - it is a question of water consumption.The fact that the apartment buildings main heating channels come into the house, pass through all the apartments, then leave it.

There are so-called pipe forward and reverse flow.If you connect the system with water heated floors to the main pipe downstream, the heating of your space and consumes a considerable amount of heat energy.Therefore, your neighbors may feel uncomfortable with the battery is not very hot, it is unlikely that you will add to the popularity of the entrance.

recommended to connect the heated floor system to the main heating only backstop pipe.In this case, the closer your room is located to the end of the pipe heating cycle - the less discontent will have your neighbors.

However, if you intend to heat the heated floor small room - for example, well-insulated balcony of a few square meters, the overall heat loss can be neglected.

preparatory stage

first step of your work on the creation of a system of water heating from the floor heating should be drafting.Take a piece of graph paper and draw on it the scheme of your room.Note the point of entry and exit of water supply pipes and pipeline laying drawing contours floor heating system.


Connection Water heating a small room to the main floor heating does not require large expenditures.

you need to stock up on:

  • -trubami for water heating.

However, you can purchase a connection and the collector node is already in the collection, which will greatly facilitate your works on its installation.

Schematic diagram of the installation of the heated water from the floor heating is shown in Figure

algorithm for creating the heated floor system

The first phase of construction you will need to mount the cabinet of the water reservoir.

Assemble connecting the circulation unit.Its task is to regulate the flow of coolant, maintaining its specified parameters, except in cases of damage due to system pressure drops.

Then, connect and check the manifold block.Its tasks include the distribution of the coolant flow for individual heating circuits.For large facilities we recommend the creation of several heating circuits.The manifold block has a supply and return manifolds, which are mounted on flow and shut-off valves.If necessary, the electrical servo valves, flow regulating effect can be established.

assembled structure is installed in the collector cabinet.With the main heating system it is connected through a ball valve.

Thoroughly clean the room in which you are going to mount a heated floor.If necessary - Vacuum.

Check the level of the floor surface.It should be strictly horizontal.

After preparing the floor spread out along the perimeter walls of damping tape.It will prevent the screed from the occurrence of cracks at the thermal deformation.

In addition, the damper tape reduces heat loss through the walls.The tape should protrude above the surface of a future tie and topcoat.

If your ceiling may be wetted from below - lay on the floor waterproofing and vapor barrier material, such as thick polyethylene film.

Over Lay Styrofoam plates, which simultaneously will act as a thermal insulation and will serve as a support for piping.

To improve the quality of the floor take the plates, which are joined at the edges of the grooves.

In accordance with the selected circuit layout, place on plates of piping water floor heating.

conducts tests of the heated floor system - open the inlet valve.

If your system is the heated water floor heating keeps powered from leaks during the test - proceed to fill it with concrete.Do not forget to add grout floor heating plasticizer - a common liquid soap can be used for this purpose.

After the final drying on the heated floor with water heating can be laid floor finish.
