Wall installation
Installation can be performed on prefabricated, brick and plasterboard walls. If demand for heat is relatively low (approx. 50 W / m2), one exterior wall should be sufficient for the installation. It is possible to install piping under the window.
Pay attention to the furniture and images covering the wall as they can reduce thermal efficiency. If it’s possible, move them by a minimum of 5cm from the wall.
In order to avoid cracks in the plasterboard, it should be strengthened with fiber-glass mesh with a mesh size ranging from 4x4mm minimum to 7x7mm maximum. The mesh must extend beyond the area of the heated parts by 25 cm on each side. At least 2 layers of plaster should be placed afterwards with one layer of mesh between them. The first layer should cover the pipe with a thickness of approx. 2/3 of total thickness, then the second layer should have a thickness of approx. 1/3 of total thickness (usually around 1,5cm)
The total thickness of the plaster is 3-4cm
It is recommended to mount the knee vent with ½ " diameter on the highest point of the wall. This step can also be omitted, in such case venting occurs by the free movement of the water in the system and slow ejection of it from there
Pipes can be easily located in the wall with a metal detector
