NOVA SYSTEM:

Nova is what is known as "real heating on demand", a system right at the state of the art. It provides heating exactly when and exactly where you really need it - and exactly what you need. Thanks to the extremely fast reaction time, the system can be activated at specific times and in just the right volumes in dining areas, kitchens, bathrooms, around the TV, in leisure areas, or at the workplace. The Nova system from Sonnstrahl needs no cement floor; the structure of the Nova system means 100 % thermal insulation, or, in other words, you gain additional insulation by doing away with any cement floor. The structure is hard insulation, x cm + 2.5 cm cellular glass, 6 mm heating surface, and the final covering such as tiles, marble, or parquet. A major drop in heating costs simply goes without saying, and becomes the normal state of affairs - and very nice too. Control is provided by room thermostats and floor controllers (in every room). Areas of use are all living areas, offices, and so on. Output per square metre 80 to 260 Watt, 220 Volt AC or DC, full screening, waterproof. The Sonnstrahl Nova system saves a lot of work and is easy to manage; insulation, heating system, and original floor covering can be completed in one single day, depending on size.
