How much electricity consumed warm floor ?

power heating elements

main types of electric underfloor heating is a film (infrared), termomat and heating cable.As for the coating film, it is commonly used in systems for laying laminate and linoleum, mats and cables are used for underfloor heating of the tiles.Each of these heating elements their characteristics: capacity, thickness, heating temperature, etc.Now we look at how much electricity consumed warm floor of each species.

Thus, the power consumption of the heating elements from the following:

• film coating - from 150 to 400 W / m2;
• heating cable - from 10 to 60 W / m (an average of 30 watts).Typically, 1 square meter of surface fits about 5 turns of the material to the total capacity was 120-150 W / m2;
• termomat -. 120 to 200 W / m2 (average consumption is taken on the characteristics of manufacturers of warm floor DEVI and TEPLOLUX).

As you can see, the power of the electric floor heating an average of 120 to 200 W / m2, which allows you to make the system for full-room heating and for the support.

costs counting technology

to independently determine how many takes electric floor heating energy, you must use the following formula:

W = S * P * 04 ,

where:

• S - area of ​​the premises;
• P - capacity of the system;
• 0,4 - coefficient taking into account how much of the floor in the room lay a cable / film.In other words 0,4 * S - Useful heating area.

Useful heating area

So, for example, if you decide to calculate the energy consumption of electric underfloor heating 150 W / m2 in the living room of 25 m2, the formula will look like:

W = 25 * 150 *0,4 = 1500 W, which means a consumption of 1.5 kWh.

Hourly consumption known, but it is still not all.As a rule, the heating system is working 8-9 hours a day, when all the residents are at home.Total daily cost of electricity will be approximately 12-13,5 kW.Simple calculations can be determined that the monthly consumption of a warm floor will be about 360-400 kW.

immediately draw your attention to the fact that these estimates are very rough and, as a rule, actual consumption is less than 2 times.This is due to the fact that in addition can be used thermostats that have a 40% cut power consumption.Total, the system will consume 360 ​​kWh per month, and 216, in addition, we have chosen an example output of 150 watts, and you can use the cable with the characteristic of 90-120 W / m2, which may be enough for individual conditions!

last thing you have to do - multiply the power that consumes system per month for the cost of one kilowatt of energy in your city.Total system power consumption to get ready, on the basis of which it is possible to do the analysis, such heating is beneficial or not.As you can see, the calculation formula is fairly simple.According to this technology, you can easily calculate the power consumption of the floor heating in any room: bedroom, kitchen, bathroom, and even on the balcony, the main thing - to have a calculator handy!

I would also like to note that home heating infrared film material energy consumption calculation is made taking into account that 1 square meter unheated rooms need about 60 watts of power material.For heated room, this value is reduced to 20-30 watts.This is due to the fact that the film has a high efficiency and low power consumption, which is advantageous in principle any type of infrared heaters!

How can you cut costs?

Above you can see how much electricity consumed warm floor.If we make the calculation for all the rooms, then come out a decent amount "of light" at the end of the month.Of course, when the first payment receipt you think about how you can reduce costs and make the system cost-effective heating.

So, to your attention tips that will significantly reduce the electricity consumption of underfloor heating in the house:

1. Make quality insulation of the house.Experimentally it has been determined that a good thermal insulation reduces the power consumption by 35-40%, which is virtually half!
2. sure to set the thermostat on the wall at the coldest point of the room.Thus, the heating will be switched on when the temperature drops below the set point, and vice versa - off when sufficient heating of the room.Regulators of temperature, as we have said, can reduce up to 40% of consumed electricity.
3. Set in the house multi-tariff electricity meter in which night-time tariff for electricity is less than 1,5-2 times (depending on the region).Anyway, the electric floor heating will work with your presence, and it is just in the evening when you come home from work.So why pay more?About the most important pros and cons of dual-rate electricity, we told you, at the same time giving the customer reviews.
4. Perform packing material only usable area.It is not necessary to make installation under the furniture and household appliances, it is not advisable from the point of view of reducing consumption and also prohibited by the manufacturers of heating materials.
5. you can sacrifice a little heated, lowering the room temperature by only 1 degree.Minor donation reduces the power consumption of the electric floor heating by as much as 5%!

That's all that I wanted to tell you about this issue.Now you know how much spending power such heating system, and how to reduce their own consumption!

• floor heating as the main heating
