| Cable mats | Medium | Up to 4 mm | 5000 UAH/2 sq. m |
Choosing the right materials for underfloor heating is an important step. It ensures effective and safe operation of the system. Therefore, it is better to consult specialists for advice.
Preparation for installation
Before installing electric underfloor heating, you need to prepare the room. Measuring the area will help determine how much material is needed. You also need to check the condition of the floor.
For installation, you need to choose the right tools. For the water system, pipes and heating elements are needed. For electric floors, cables and thermostats are required.
Electric floors should be installed on a flat surface. Unevenness can lead to poor distribution of the screed. This will affect the efficiency of heating.
The insulation material should have a thickness of 2-5 cm to retain heat. The density of the insulation should be more than 3.5 kg/cm³. The minimum distance between cables should be 30 mm.
Stages of underfloor heating installation
The installation of underfloor heating includes several important stages. The first stage is creating the contour. It shows where the heating elements will be located. After that, the pipeline or cable is laid, depending on the type of heating system.
Connecting to the heating system depends on the heat source. For heating “cold/wet rooms,” it is better to use an electric cable with a power of 170 W/m². In “dry” rooms, an electric cable with a power of 130-140 W/m² is sufficient.
When choosing an underfloor heating system, it is important to consider the type of room. Laying underfloor heating cable is done taking into account the step and power. For the main heating of living rooms, a cable with a power of 160-220 W/m² with a step of 75-100 mm is selected.
Methods of laying underfloor heating
Choosing the method of laying underfloor heating is important. There are three main methods: wet, dry, and combined. The wet method uses water, while the dry method uses dry materials. The combined method combines both.
It is recommended to use the wet method on 70-80% of the room area. For additional heating, it is better to use the dry method on 40-50% of the area. The minimum laying step should be 7.5 cm.
The laying step of the cable should be eight times greater than the diameter of the cable. The thickness of the insulation should be 2-5 cm. The density of the insulation should be more than 3.5 kg/cm³.
To connect the underfloor heating, it is important to correctly select the laying step of the cable and pipes. The distance between the loops of the heating cable should be from 7.5 to 10 cm. The maximum power of the thermostat is 16 Amperes, which corresponds to 15-20 m² of floor.
The consumption of self-leveling mixture is about 1.8 kg/m² per 1 mm. To cover the mat, it is necessary to pour 6-7 mm, which amounts to about 13 kg (~100 UAH) per 1 m². The drying time of the screed is 24-48 hours.
Adjustment and settings of the system
To achieve a comfortable temperature in the room, it is necessary to adjust the heating. The settings include the thermostat, testing, and energy saving. Underfloor heating systems, like boiler installations, require precise adjustments.
The system setup includes several stages. Start with balancing the circuits. Then adjust the pump-mixing unit and controller. The temperature difference should be 5-10°C, with an average value of 7°C.
The floor temperature in places where people stay permanently should not exceed 29°C.
Tips for system adjustment
- Measure the temperature in 5-6 points of the room and average the data for more accurate adjustment.
- Maintain the temperature difference between supply and return (Δt) at 5°C.
- Calculate the specific consumption of the heat carrier using the formula Gпит = Q/(1.163*Δt) and multiply it by the floor area S (m²) to calculate the consumption of the heat carrier through the circuit.
The underfloor heating system works better with regular maintenance. Also, monitor the floor temperature. In places where people stay permanently, it should not exceed 26-29°C, in temporary places – 35°C.
