Panel or sectional radiator — what to choose
“Panel or sections?” is not a taste question — it is about mounting, output and the system. Both can be good; mixing requirements is bad. Main guide: how to choose a radiator.
Short comparison
| Panel (C11/C22) | Sectional | |
|---|---|---|
| Looks like | One “box” with fixed length | Assembleable sections |
| Output | From type + size (C22 > C11 at same footprint) | From section count and model |
| Mounting | Typical hydronic replacement | Often different connection/kit |
| Examples | Purmo C11 500×500, C11 500×400, C11 500×600, IMAS C22 500×500 | Fondital Simun 4 sections |
| When | Standard renovation, under-window niche | When project/old system needs sections |
When to take a panel
If you replace a typical steel panel under the window and connections are clear — the C11/C22 line is the safer path. Start with space and output, then length. In the Inventars range Purmo C11 and IMAS C22 are good “teaching” examples of how a type change alters output without a huge niche change.
When to look at sections
If the existing system is sectional, or the project specifies aluminium/sectional — do not try to “force” a panel by eye. Fondital Simun shows sectional logic: sections count, not only mm length like a panel.
What not to mix up
- C22 is not “sections” — it is still a panel with two panels.
- Section count ≠ automatically “better than C22” — compare W and connection.
- Valves must match the chosen type — valves.
FAQ
Can I replace a panel with sections 1:1?
Only if connections, supports and hydraulics allow. Often that is a project, not “the same mm”.
Which is “warmer”?
The one with enough output on the card for your ΔT and room — not the “nicest type”.
