Construction

Picture of the structure of Parquet on Carbon underfloor heating.
  1. Real wood parquet: Choose your preferred wood from one of our trusted IREWA partners. We recommend oak due to its minimal swelling and shrinkage during temperature fluctuations between summer and winter.

  2. IREWA Carbon underfloor heating: Our full-surface carbon heating layer heats your room quickly and evenly, creating a cozy atmosphere.

  3. Insulation: It reduces heat loss and ensures efficient use and targeted distribution of heat energy.

  4. Reflection layer: Our patented structure improves the heating performance in your room by reflecting residual heat upwards into your room instead of wasting it unused in the floor. This saves you a lot of money.

Less Losses

Each room generates the exact amount of warmth needed – right where it is needed.
The following types of losses are eliminated:

Control losses
No over or undersupply of heat due to in-room heat generation

Transmission losses
No fuel-water-screed or other heat transmissions

Transportation losses
No pumps needed to transport hot water for heating

Heat storage losses
No direct heating of screed, no storage of hot water

Unique Bonus: Patented Thermal Deccoupling

Our patented structure with a reflective element prevents heat losses into the ground:

Keep more heat in the flooring, less loss in the ground

Quicker warm-up times Less consumption

Less consumption costs

Traditionell:

kleine effektive Heizfläche (gelb)

Mit Carbon:

große effektive Heizfläche (gelb)

Je größer die effektive
Heizfläche, desto
schneller ist die Wärme
im Raum und desto kürzer
muss die Heizung laufen

Advantage:

Vollflächige Heizung ermöglicht niedrigere Temperaturen: 20-24°C (spart Energie)

Direkte Erwärmung des Bodenbelags führt zu schnellerer

Aufwärmzeit Schnellere Aufwärmzeiten führen zu kürzerer Laufzeit

“The simple recipe for Cost Efficiency and Comfort: Temper large surfaces (floor or ceiling) to low temperatures (20-24°C).”

Warum die Wärmeübertragungsmethode wichtig ist:

1 kW elektrische Eingangsleistung entspricht NICHT 1 kW thermischer Leistung.

Beispiel 1: 
Ein Elektroherd und ein Induktionskochfeld erhitzen einen Liter Wasser mit der gleichen Menge Strom

1000 W

6:23 min

1000 W

2:18 min

Auf dem Induktionskochfeld kann das Wasser viel schneller zum Kochen kommen, da der Strom effizienter zum Erhitzen des Wassers genutzt wird.
Beispiel 2: 
Unterschiedliche Heizsysteme mit gleicher elektrischer Eingangsleistung:
Elektro-Heizlüfter

3000 W

Nachtspeicherheizung

3000 W

IREWA Fußbodenheizung

3000 W

Verbrauchsdaten werden variieren:
Unterschiedliche Übertragungsmedien (Konvektion / Strahlung)

• Unterschiedliche Heizflächen

• Unterschiedliche Laufzeit der einzelnen Systeme zum Aufheizen des Raumes
