The low-temperature Compact Softline heating unit is made of fine cold-rolled sheet steel to EN442-1 quality, with side panels and a top grille, forming a compact unit with a vertical water channel spacing of 33.3 mm. The convector fin is welded to the internal channels. Before painting, all radiators go through a multi-stage cleaning process, including iron phosphate treatment and a demineralised rinse. A primer coat is then applied, followed by a powder coat finish in Stelrad white 9016. Each radiator is packed in a carton with sturdy corner protectors and protective film. All units have wall brackets on the back. Quality is certified to EN ISO 9001. Thermal output is verified to EN 442. The design complies with BAGUV safety guidelines.

Frequently Asked Questions

• What is the output of this specific radiator (900 x 900 mm, type 33VK)? This size and type has a declared thermal output of 3001 W (according to EN 442, at standard temperature gradient) - when choosing the correct radiator size, base your decision on the calculated heat loss of the room in question.
• What does the type designation 33VK mean? The number before "K" (e.g. 11, 20, 21, 22, 33) indicates the radiator's construction type - the number of radiator panels/plates and convector fins in its construction; a higher number means more layers and therefore higher output at the same external dimensions. The "V" designation in the type means bottom connection (valve-compact) - the connections are located on the bottom edge of the radiator, which is particularly suitable for underfloor pipe routing without visible risers.
• What is the maximum operating pressure and temperature? The radiator is designed for an operating pressure of up to 1,0 MPa and a heating water temperature of up to 110 °C, with a test pressure of 1,3 MPa - typical domestic heating systems operate well below these values.
• What is the warranty on the radiator? The manufacturer provides a 10-year warranty on tightness and thermal output from the date of manufacture, provided professional installation, correct maintenance and operation are observed - the warranty does not cover mechanical damage caused during transport, handling or improper installation.
• Must installation be carried out by a professional? Yes, connecting the radiator to the heating system (single-pipe or two-pipe, with forced circulation) should be carried out by a heating engineer/plumber, who will also ensure correct venting and balancing of the circuit.
