Braided tube FOXIS installations are perfectly covered by narrow in- front-wall plasterboard where space at bottom and top air-outlet is.

Power of wall is ca 600W/per m (75/65/20°C)
if the tube is connected through flex hoses than is lifted above space at bottom, you can gain absolutely clear design. Heat power calculation is attached. For correct heat power calculation – please count with high of cover of heating tube FOXIS 90cm. Calculation is limited up to this mentioned high, otherwise the heating power of tube is not getting raised.
