Aluminium and steel stretch differently when heated. The coefficient of linear thermal expansion of steel is 12.0 · 10-6 [m / mK] and of aluminium 22.2 · 10-6 [m / mK], which is nearly twice as high. Our designers have solved this problem as follows: As described above, the steel pipes and the heating surfaces are not welded together, so they can expand separately. When connecting several panels, the aluminium elements are not fixed together. The bottom covers are only attached to the pipes. In this way, only the pipe extension has to be considered.
Pay close attention to the expansion, especially when low slopes or high temperatures are planned.

The pressure losses in the KSP to go® range of goods can be divided as follows:
The pressure losses of the radiant panels Δp1 can be found in Diagram 1. There you will find the data for each KSP to go® type depending on the flow rate. The values given are the pressure losses per meter and must always be multiplied by the total length of the heating tape.
The pressure losses of the KSP to go® distributor Δp2 can be found in the diagram 2. For clarity are the total values per strip already summed, so you can directly transfer the value in Pa or mbar. Alternatively, you can calculate the value yourself using the kvs values in the following table.
|Distributor kit KSP to go®600 (Box 4)||7,40|
|Distributor kit KSP to go®900 (Box 5)||8,13|
|Distributor kit KSP to go®1200 (Box 6)||6,12|
|2 pcs KSP to go®-stainless steel corrugated hose||5,94|
KSP to go® radiant panels are an extremely comfortable and energy-efficient heating system. They offer cozy warmth, freedom of drafts, dust and annoying noises. Admittedly, the initial investment is slightly higher than other heating systems. However, this pays for itself quickly through energy efficiency, maintenance-free operation and an extremely long service life. Hardly any product has such low lifecycle costs.
Let yourself be inspired.

You plan a room with the following dimensions: L x W x H = 6 x 4 x 3.5 m Heat losses: 1,700 W (ti = 18 ° C)
Condensing boiler: (tw1 =70 °C, tw2 = 55 °C)
Our online calculator calculates: 2strips, each 4 meters long, KSP to go®600
|Box Nr.||Content||Piece||Qi,pc [W]||Qi,BAND [W]||Qi,TOT [W]|
|Box 1.2||KSP to go®600 / 2 m||4||554||1108||2216|
|Box 4||KSP to go®-Distributor kit 600||2||135||135||270|
|Box 7||KSP to go®-Connection kit 600||2||0||0||0|
As you can see, the pressure losses in this case are minimal. In general, these will be very low in most of the KSP to go® projects. This is why the control capability of the KSP to go® range is generally very high.
