Comfort Heat CTAV-10, Installation Instructions Manual

2. CONCRETE FLOOR HEATING

The system of heating cables can be the main (the only) heating source of 

premises but also can supplement other ways of heating - water or electric panels, 

fireplaces. Then we shall arrange system of the “heated floors”.

The heating cables are installed in a free space of floor (not covered with steady 

equipment freezer, cooker, kitchen furniture, bath, washing machine, etc.), in 35 mm 

layer of the concrete. Using CTAV-18 cable which has 18 W/m power, the distance 

between the cable loops (C-C) is 5-15 cm. Such a layer of concrete and the distance 

between cable loops is important for evenly spread of heat and helps to avoid the 

fluctuations of temperature.

The thickness of floor can be reduced by pouring self-levelling compound over 

the cables CTAV-18, CTAV-10 or installing cables directly in the layer of tiles adhesive.

The distance C-C is simply to keep using mounting tape (the distance is 25 mm).

The mounting tape is laid in 50-100 cm distance. The consumption of tape is 1-2 

m/m

. Tape is fixed by nails or glued.

3. FLOOR HEATING BAsE ARRANGEmENT

If you want to have the floor giving comfort and heat to your house, first of all 

you have to arrange the base for heating floor (

).

6. Damp insulation (in bathrooms)

7. Layer of adhesives or self-levelling compound

8. Tiles or other flooring material

It  is  very  important  that  construction  of  heating  floors  have  good  thermo 

insulation, otherwise big part of heat will be lost. Especially this is important when 

unheated cellar or ground is under the floor.

The thermo insulation of vertical edges of heating zones (outer walls) secures 

the heat does not flow to the sides, walls or unheated areas. Besides, the vertical 

insulation absorbs horizontal expansion of floors because of heating.

ATTENTION! Heating cable cannot touch the thermo insulation material.
