Warm floor with your hands from heating: step by step instruction and installation

click fraud protection

A good feature of a heated floor with a liquid coolant is that it can be installed using existing communications, for example, main heating systems.

In this case, the heating of the premises can be done as a combined, that is, with the simultaneous use of heating radiators and a system of pipelines in the floor, and exclusively using only the piping system of the heated floor.

The only, but very important nuance that must be taken into account when connecting the heated floor system to the main heating is the issue of water consumption. The fact is that in multi-apartment buildings the main heating channels go into the house, pass through all the apartments, and then leave it.

There are so-called straight and reverse flow pipes. If you connect a system of water heated by the water to the main pipe of direct flow, then a significant amount of thermal energy will be used to heat your premises. Consequently, your neighbors can feel the discomfort of not very hot batteries, which is unlikely to add to your popularity in the entrance.

It is recommended to connect the heated floor systems to the main heating only on the return pipes. At the same time, the closer your room is to the end of the cycle of heating pipes, the less displeasure your neighbors will have.

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

Preparatory stage

The first stage of your work on creating a system of floor water heating from heating should be drafting. Take a sheet of millimeter paper and draw a diagram of your room on it. Mark the points of entry and exit of the water supply pipes, as well as the drawing of the installation of the pipeline contours of the heating system of the floor.

Required materials

Connection of water heating of a floor of a small premise to the main heating does not demand the big expenses.

You need to stock up:

  • -pipes for water heating.

However, the connection and manifold assembly can be purchased already assembled, which will greatly facilitate the installation work.

The algorithm for creating a heated floor system

At the first stage of construction, you will need to mount a water collector cabinet.

Assemble the connecting circulating unit. Its task is to regulate the flow of the coolant, to maintain its specified parameters, excluding the case of system damage due to pressure drops.

Then connect and inspect the manifold block. Its task is to distribute the flow of coolant through separate heating circuits. It is recommended to create several heating circuits for a large room. In the collector unit there is a supply and return manifolds on which flowmeters and shut-off valves are mounted. If necessary, electric actuators can be installed in the valves to regulate the force of the water flow.

The assembled structure is installed in a collector cabinet. With the main heating system it is connected via ball valves.

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

After preparing the floor, spread the damper tape along the perimeter of the walls. It will protect the screed from the occurrence of cracks during thermal deformation.

In addition, the damper tape reduces the heat loss through the walls. The tape should protrude above the surface of the future screed and the finish coat.

On top of the expanded polystyrene plates, which at the same time will serve as a thermal insulation and will serve as a support for pipelines.

To improve the quality of the floor, take the plates that are connected with grooves along the edges.

In accordance with the chosen scheme of layout, place on the plates the pipeline for floor water heating.

If your system is heated by water floor, powered from the heating maintains tightness during the test - proceed to fill it with concrete. Do not forget to add a plasticizer to the solution for pouring the warm floor - you can use the usual liquid soap.
