Mono, Duo or Trio: how to choose for your radiator
31/10/2026

To choose your kit, the measurement that counts is the width of your radiator, from one edge to the other.
Which kit for which width?
- Mono Kit: 1 fan bar (3 propellers), for radiators from 40 to 70 cm.
- Duo Kit: 2 linked bars (6 propellers), for radiators from 70 to 120 cm.
- Trio Kit: 3 linked bars (9 propellers), for radiators from 120 to 180 cm.
Check your radiator type too
Our kits are designed for hot-water panel radiators and finned convectors. Towel rails and some designer or electric radiators are not always suitable. If in doubt, write to us with a photo of your radiator.
