How to install warm floor heating installation steps

Floor heating is not only winter heating equipment, but also related to the interior decoration layout, good floor heating installation will undoubtedly add icing on the home improvement, to achieve the perfect combination of comfort and energy saving. How to install the floor heating in the home heating decoration construction? What is the process of installing the floor heating? Let's take a look at the warm-up installation steps and hopefully we can help everyone.

Warm installation steps

Floor heating installation steps - water heating installation steps

First, pre-installation inspection

Before the construction, the installation company should first test the ground leveling screed and hand over the site to the owner to determine the position of the thermostat, diverter, wall-hung boiler, and boiler flue hole. At the same time set the need to reserve the size and size, easy to install the company to walk the wiring.

Second, install the water heating manifold

The manifold is installed in a pre-determined position and the installation is straight and firm. Wall-hung boilers and wall-hung boilers locate and determine the position of the flue.

Third, laying insulation board

Cut the insulation board according to the actual size, lay it out, and leave a gap for the pipe when laying. Heating materials include heat sources (wall-hung boilers), radiator ends (heating radiators), pipe fittings and temperature control systems. During the process of laying insulation boards, the site should be kept clean and tidy, and the insulation boards are mainly used for insulation, so as to prevent the ground heating temperature from being transmitted downward during use.

Fourth, laying reflective film and wire mesh

The reflective film shall be tightly attached to the heat insulation board, and the function of laying the reflective film is to prevent the heat of the floor heating tube from radiating downwards (ie, radiation conduction). The laying of the steel wire mesh may fix the pipe, increase the bearing weight of the pipe, and effectively prevent cracking of the floor.

Fifth, laying pipe

The laying of floor heating pipes has high requirements for construction technology. To ensure uniform heating and cooling during later use, the laying of floor heating pipes requires that the floor heating pipes must be evenly distributed on the ground. The distance between the pipes and the pipes is 200 mm. After laying, plastic cards are used. Secure the floor heating pipe to the insulation board. Be careful not to contaminate the pipe during installation.

Six, connecting the floor heating pipe and the water collector

Connect the heating pipe to the manifold and check for damage to the pipe and perform hydrostatic test on the system. After checking that the pipeline laid is not damaged and the spacing between the pipes meets the design requirements, the system is first flushed and then the hydrostatic test is performed.

Seven, laying concrete layer

The concrete layer protects the entire floor heating system. It can fix the water pipe, protect the water pipe from being deformed due to thermal expansion and contraction, and at the same time make the heat distribution more uniform and the user feel more comfortable.

Eight, lay the ground material

Composite floor and tile are more suitable for warm floor materials. Tiles have good thermal conductivity and strong resistance to deformation. They are ideal for floor heating. In recent years, many solid wood floors that have undergone processing can also be used for floor heating. At this time, it is necessary to understand clearly before proceeding with the optional installation.

Nine, install the boiler

Install the boiler to debug the water temperature and hydraulic balance of the entire water supply loop.

Floor heating installation steps - electric floor heating installation steps

Electric floor heating is becoming more and more common. Let's take a look at the general steps of its construction:

1, laying insulation layer

Polystyrene insulation boards should be laid on a clean, clean surface. When laying, it should be cut and tidy, the gap should not be greater than 10mm, and the application of adhesive tape between the insulation boards is smooth.

2, laying steel mesh

The steel mesh is laid on the polyester vacuum aluminum plating film, and the joints are tied with a binding band to secure the steel meshes to be overlapped and bound and fixed. If the cable is fixed with staples or the heating cable is fixed with a fixing strap, the steel wire mesh should be laid in a pebble concrete filling layer.

3, lay the heating cable

The heating cable must be laid on the wire mesh at the spacing required by the design drawings. The heat-generating cable should be fastened to the wire mesh with a binding band, or the heating cable should be fixed on the heat-insulating layer with a fixing band or a staple.

4, measuring wind with heat

After the heating cable is laid, check whether it meets the design requirements according to the drawings and check the nominal resistance and insulation resistance of each cable with a multimeter and a megger (500MΩ) to ensure that the heating cable has no open circuit or short circuit. Before the pouring of the pebble concrete, it is necessary to electrify the heating effect of the heating cable.

5, cast pebble concrete filling layer

When the pebble concrete enters the paving area, it must be transported by a pallet, and the trolley and other tools cannot directly press the heating cable; after the concrete is poured, the wooden tools are used to lightly compact it, and it is not to be vigorously roughened; the filling layer is not allowed to be trampled within 48 hours after the completion of the filling layer. After the construction of the filling layer is completed, it is strictly prohibited to cut and reload.

6, cable test again

After the construction of the filling layer is completed, each cable shall be inspected with a multimeter and a shaking table (500 MΩ) to check whether the heating cable is damaged during the construction of the filling layer.

7, thermostat installation

Should be installed before the project is delivered for use. The thermostat installation and operation instructions shall prevail during the installation. After the installation, the power supply should be tested. After the inspection, it should be wrapped with tape to avoid damage.

Concluding remarks: The requirements for installation of the floor heating project are high. The professional installation team must complete the construction to avoid unnecessary troubles in later use. The above steps about floor heating installation are briefly introduced here and I hope to help you. For more information, please visit this website. Stay tuned.


Circular saws are most frequently used Power Tools on woodworking. They are categorized according to their drive motor, the type of depth control they use, their cutting depth and power input. Circular saws are available in general-purpose and special versions. Typically, hand-held circular saws are mounted on a base plate.
