Compact Softline low-temperature heating body is made of fine cold-rolled sheet metal to EN442-1 quality, with side panels and a top grille as a compact unit with a vertical water channel spacing of 33.3 mm. The convector sheet is welded to the inner channels. Before painting, all radiators go through a multi-stage cleaning process, including iron phosphate phosphating and demineralised rinsing. A base coat of paint is then applied, followed by a powder coating in Stelrad 9016 white. Every radiator is packed in cardboard with sturdy corner protectors and protective film. All bodies have mounting brackets on the back. Quality is certified according to EN ISO 9001. Thermal output is verified according to EN 442. Design complies with the BAGUV safety guidelines.

Frequently Asked Questions

• What is the output of this specific radiator (400 x 900 mm, type 33VK)? This size and type version has a declared thermal output of 1540 W (according to EN 442, at the standard temperature gradient) - when choosing the correct radiator size, base your calculation on the calculated heat loss of the given room.
• What does the type designation 33VK mean? The number before "K" (e.g. 11, 20, 21, 22, 33) indicates the radiator's structural type - the number of radiator panels/plates and convector sheets in its construction; a higher number means more layers and therefore a higher output at the same external dimensions. The "V" in the type designation 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 overpressure of up to 1,0 MPa and a heating water temperature of up to 110 °C, with a test overpressure 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 the 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/installer, who will also ensure correct venting and balancing of the circuit.
