Charging floor heating

Varaava lämmitys on edullista, jos sähkön hinta on yöllä merkittävästi alhaisempaa kuin päivällä.

In charging floor heating, the heating cables are cast inside the concrete slab of the floor The heating energy moves to the floor covering and is transmitted into the room.

Principle

Charging floor heating 'stores' the heating energy in the floor structure. When the less expensive night tariff becomes valid in the evening, the heating is turned on. A thermostat measures the floor temperature and turns the heating off, when the preset temperature value is reached. In the morning, the heating is turned off, and the floor structure acts as a heating appliance until the evening. The necessary power is 80-100 W/m2.

Applications

Charging floor heating requires a thick (6-10 cm) concrete slab, which means that it is not suitable for light floor constructions. Neither can it be installed later, because the cable must be installed deep inside the slab.

Heaters

The best product for this application is AS•MI TXLP 17 with a power of 17 W/m. The cables are cast in the middle of the floor slab and the distance between cable runs is 15-20 cm.

Cost savings

Charging floor heating is economic, if the night tariff of electricity is significantly lower than the day tariff.

Comfort

On a cold day, the floor can discharge so much of the accumulated heat that the room temperature can't be kept on the desired level without additional heating. Therefore, we recommend ceiling heating to be installed in front of the windows to compensate heat losses.

Control

The heat that is accumulated in the floor is discharged freely - this process can't be controlled with a thermostat. A floor thermostat is used to control the charging to prevent overheating of the floor. If also ceiling heating is used, the best result is achieved with a combination thermostat, which measures also the ambient temperature.
