Frequently asked questions about the Radiators category
Radiators — what are they and which heating systems suit the Radiators category?
Radiators — they are heating units that deliver heat to a room via a hot heat-transfer fluid; our category includes aluminium and bimetal radiators, towel rails and fittings suitable for central and domestic systems, typically rated up to 16 bar and up to 110°C.
What are the advantages of aluminium radiators vs bimetal radiators?
Aluminium radiators are lighter, heat up faster and provide high heat output in a compact size; bimetal radiators are stronger under high pressure and more corrosion-resistant, making them preferable for communal or high-pressure systems.
How to choose radiator size and number of ribs for a room?
Estimate the room heat loss or use a rule of thumb: a 10–12 m² room typically needs a 500 mm high radiator with 6–10 ribs; select models like Plus Evo or Biliner in the required rib count from our catalogue.
Are the towel rails in the catalogue suitable for wet bathrooms?
VARMIKO and TERMINUS towel rails are designed for connection to central or domestic heating systems and come with side and bottom connection options; check thread type and system working pressure compatibility before selecting.
Which fittings are needed to connect a radiator and are they in the catalogue?
You need brackets, nipples, DN15 thermo-kits, air vents and plugs; the catalogue includes AL.RAD.NIPPEL, TERM.KOMPL DN15 and various valves/air-bleeders for standard installations.
Can an aluminium radiator be used with a cast-iron boiler and steel pipes?
Aluminium radiators can be used, but with steel piping you must control the heat-transfer fluid chemistry (corrosion inhibitors); if in doubt, choose a bimetal radiator for greater resistance to electrochemical corrosion.
What sizes of radiators and towel rails are available in the category?
The catalogue includes radiators commonly 500 mm high with various rib counts (6–12), and towel rails in standard sizes 500×500, 500×600, 500×800 and 500×1000 mm in VARMIKO and TERMINUS models.
How do BILINER BIMETALL and PLUS EVO models differ?
BILINER BIMETALL is a bimetal design with a reinforced steel core for high pressures; PLUS EVO is an aluminium radiator offering high heat output and various rib configurations for compact heating.
What control elements and thermo-kits are offered for radiator regulation?
The catalogue includes DN15 thermo-kits and Heimeier/PROFACTOR valve kits for side and corner connections; these enable connection of thermostatic valves and precise temperature control.
