The Compact Softline low-temperature radiator 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 phosphating and a demineralised rinse. A primer coat 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 units come with wall brackets on the back. Quality is certified to EN ISO 9001. Heat output is verified to EN 442. Design complies with BAGUV safety directives.

Frequently asked questions

• What is the output of this specific radiator (400 x 1600 mm, type 22K)? This size and type has a declared heat output of 1992 W (to EN 442, at the standard temperature drop) - when choosing the correct radiator size, base your choice on the calculated heat loss of the room.
• What does the type designation 22K 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 it consists of; a higher number means more layers and therefore higher output at the same external dimensions. A radiator without the letter "V" in its type has a side connection - the classic placement of connections on the sides of the radiator, suitable for standard side pipe routing.
• 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 - ordinary 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 heat output from the date of manufacture, provided professional installation, correct maintenance and correct 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/installer, who will also ensure correct air venting and balancing of the circuit.
