Technical Data

The innovative technology of the patented IREWA carbon floor heating system – efficient warmth for your home, office, and commercial spaces.

The full-surface warmth of IREWA Carbon underfloor heating.

IREWA Carbon underfloor heating

We have printed the entire surface of the IREWA underfloor heating system with our patented carbon coating.

The larger the effective heating surface, the faster your room will be comfortably warm, and the
shorter your heating will need to be running.

Warm feet in just 15 minutes.

Conventional underfloor heating

With traditional water-based underfloor heating, the heating elements are heated in a lengthy process to heat your room.

Regulation is laborious, requires a lot of effort, is time-consuming, and costs you
a lot of money.

Warm feet in at least three hours.

Construction

The IREWA Carbon underfloor heating is a
bestseller throughout Europe since 2012.

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
