The new Vitosol 300-F is a high performance flat-plate collector. It is ideal for DHW heating and central heating backup. High quality ensures permanent operational reliability and a long service life.

High solar energy utilisation. Through its anti-reflex glass, the highly selectively coated copper absorber utilises the intensive solar irradiation particularly well. The meander shape of the absorber ensures an even and reliable flow through the entire collector. The result is the assurance of high solar energy utilisation and efficiency.

Permanently sealed. The Vitosol 300-F casing comprises an all-round folded aluminium frame. The pane seal is endless, resilient, as well as weather and UV resistant. 

Attractive design, individual colour finishes. The Vitosol 300-F can be integrated into the roof cover. The edge trims (accessory) help to create a harmonious transition from collector surface to roof cover. Upon request, frames are also available in special colours.

Easy installation. The Vitosol 300-F is particularly easy to install. The integral flow and return pipes allow a simple and safe installation, even of larger collector arrays. Up to 12 collectors can be linked in parallel.
