#### How much material is needed to heat the premises with the area of 100 sq. meters?

We start our calculations from probable heat loss in a particular building or room. In the modern well-insulated building heat losses do not exceed 60 watts per square meter of space. In the buildings with mediocre insulation it comes to 80 watts. In the poorly insulated buildings and premises the volume of heat losses comes to 100 watts. Thus, in order to compensate for heat loss in buildings with mediocre insulation the coating with the capacity of 8000 watts is needed for the area of 100 square meters. When using Carbontec heating material with the capacity of 251 W, the consumption rate will constitute 32 square meters of the material.

#### What are the monthly heating expenditures for the house with the area of 100 square meters?

32 sq. meters of Carbontec heating material with the capacity of 251 watts are needed for heating the house with the area of 100 square meters. The average power consumption makes 40 -60 watts per square meter of the heating material.
50 W /  m2. x 32 m2 x 24 h = 38,4 kWh / day
38,4 x 30 days = 1152 kWh / month
1152 kWh / month x price 1 kWh (0,12€ in Lithuania) = 138 € / month.

#### What type of heating is the most effective: ceiling, wall or floor heating?

The ceiling heating shows the highest rate of efficiency, which comes to 98%, wall heating has 80% of efficiency, and efficiency of the floor heating comes to 60%.

#### What is the economic efficiency of Carbontec system?

Carbontec heating system completely excludes the expenditures on negotiations and obtaining of permits. The system also excludes expenses on the design and maintenance works. The electricity consumption rate comes just to 40-60 watts per square meter of the used Carbontec material, while the efficiency of the infrared Carbontec material is 2.5 – 3 times higher compared to the conventional convection heating systems, including gas heating.
