Buyers ask the wrong question: "which is cheaper to buy?" The right one is "which costs less across the life of the building, and which makes the room actually comfortable?" Dry underfloor heating and radiators answer those differently.
Comfort: where UFH wins outright
Radiators heat the air near the wall and let it rise, leaving cold feet and warm heads. A dry underfloor heating panel warms the whole floor plane at a low surface temperature, so heat radiates evenly from the ground up. The result is a room with no cold spots and no dust-convecting hot surface.
Running cost over time
UFH runs at lower flow temperatures (around 35–45 °C vs 60–75 °C for radiators), so it pairs efficiently with heat pumps and modulates gently. Per square metre the energy use is lower once balanced — but the saving only materialises with proper control and a well-insulated building.
| Factor | Dry UFH | Radiators |
|---|---|---|
| Flow temp | Low (heat-pump friendly) | High |
| Comfort | Even, feet-warm | Convective, top-warm |
| Build height | 20–30 mm (dry) | 0 mm (wall mounted) |
| Install speed (renov.) | Fast, no screed | Fast, but wall space lost |
| Running cost | Lower over time | Higher per m² |
Build height and renovation
This is where dry UFH surprises people. A traditional screeded wet system adds 50–70 mm. A dry panel system adds only 20–30 mm of panel plus a thin adhesive layer, so it drops into a renovation without re-hanging every door. Radiators cost zero floor height — but they steal wall space and force furniture around them.
Install time and labour
- Dry UFH: lay Omega-grooved panels, press pipe or cable into the groove, test, tile. No screed cure, no weeks of waiting.
- Radiators: mount, plumb, bleed. Faster to a warm room, but you live with the bulkheads forever.
When radiators still make sense
- Listed or concrete buildings where you cannot raise the floor.
- Rooms needing fast boost heat (a bathroom you warm for 20 minutes).
- Tight budgets where wall space is no object.
Frequently asked questions
Is underfloor heating more expensive to run?
Over a building's life, no — it runs at lower flow temperatures and heats evenly, so it uses less energy per square metre once controlled properly.
How much height does dry UFH add?
Typically 20–30 mm of panel plus adhesive — far less than a 50–70 mm screed, which is why it suits renovations.
Hydronic or electric?
Hydronic is economical for whole-house or large areas; electric suits a single room or top-up where simplicity matters more than running cost.
Can it go under any floor finish?
Best under tile or stone, which conduct heat. For wood or vinyl, use panels and adhesives rated for that finish and respect its temperature limit.
Does it work with a heat pump?
Exceptionally well — the low flow temperature UFH wants is exactly what a heat pump delivers efficiently.
Heat the room, not the wall
TANYTE builds dry underfloor heating panels — Omega-grooved XPS/aluminium for hydronic, graphene-faced for electric — in OEM/ODM volumes.
