Frequently Asked Questions
Do you have a question about our IREWA carbon underfloor heating? Check out our top Frequently Asked Questions that may help you to navigate our website and find out information about IREWA Heating Solutions.
How are IREWA's carbon underfloor heating costs calculated?
We use measured values from existing houses as base of our calculations. This gives us the most transparent and precise estimations.
Can I get state subsidies in Germany for the IREWA carbon underfloor heating?
Yes, it is possible to get subsidies for efficient buildings. Contact us to learn more.
Is IREWA's heating system patented?
Yes. Our patented structure allows for less heat losses, quicker warm-up times and lower consumption costs.
Has there ever been a problem with the IREWA carbon underfloor heating?
No, never has there been a problem since we started in 2012. The only thing that can sometimes break is a thermostat which can be changed within minutes.
How long does it take for the IREWA carbon underfloor heating to heat up a room?
From 17 °C to 22 °C it takes on average around 30-45 minutes, depending on the house and used materials.
Why does heating on demand save heating costs?
Because you only raise the room temperature when heat is truly needed. During absence times, the temperature drops, reducing heat loss through walls and windows. Thanks to the fast response time of the IREWA Carbon heating system, the room can later be quickly and efficiently reheated—using less energy than when maintaining a constant temperature. You can find more information here: Save heating costs.
Are there differences between the IREWA carbon underfloor heating and other underfloor heating systems?
Yes, many actually. Find out more in IREWA’s technical data.
Can I talk to homeowners who have the IREWA carbon underfloor heating installed to get a first-hand experience?
Yes, we can manage a meeting or call with customers who are willing to share their experiences with the IREWA carbon underfloor heating.
What makes IREWA confident that it will last so much longer?
A few factors: 1) We tested our products in heat chambers to quicke the aging process (125 years no problem), 2) high quality materials, “low” temperatures mean no “heavy lifting” for each component.
How long does it take to install the IREWA carbon underfloor heating?
A team of two can install approximately 75m² of the IREWA carbon underfloor heating in one day. So, a large room of around 30m² can be ready with heating and flooring in just one day.
Is the IREWA carbon underfloor heating sufficient as a sole heating system or do I need additional heating systems?
Yes, IREWA is a fully functional heating system designed to heat your entire building.
Is the IREWA carbon underfloor heating silent?
Yes, IREWA is truly silent. Our patented heating system operates completely silently.
Which floorings are suitable for the IREWA carbon underfloor heating?
The best flooring for the IREWA carbon underfloor heating is parquet, but suitable are also: vinyl (min. thickness 8 mm), laminate, tiles (with decoupling mat) or stone carpet.
Is the IREWA heating solution ecological?
Yes, in many ways, because the IREWA carbon underfloor heating uses less components than central heatings, offers more than double the life span, and no maintenance visits are necessary. On top, the installation of IREWA needs no screed, which reduces your CO₂ impact).
Are IREWA's customer happy with their choice?
Absolutely. Best you convince yourself checking out our numerous customer interviews.
Is there any component that requires maintenance?
No, because the IREWA carbon underfloor heating needs no maintenance for at least 50 years.
How are the values calculated?
For costs we use average prices from trusted sources, for time we use average waiting times and maintenance times, and the CO₂ savings can be calculated by the amount of screed that can be dispensed as well as the difference in material components needed with IREWA.
Do my legs swell from this underfloor heating?
No, with IREWA you won’t get health issues like that. Our customers regularly confirm this. Your feet only swell if the temperature is too high, usually above 26 °C.
Can I regulate the temperature of the IREWA carbon underfloor heating from work or holidays?
Yes, that is no problem with our smart thermostats.
Can the thermostat measure and regulate the ideal temperature automatically?
Yes, our smart thermostats only allow for heating if the temperature in each room is below the desired temperature.
What happens when there is a black-out?
If there is a black-out, no heating will work except for a wooden powered fireplace. Oil and gas heatings need electricity for their regulation units and pumps. Heat pumps and IR panels are electric heating systems as well.
Does it make sense to use the IREWA carbon underfloor heating in a hotel?
Yes, you can save a lot of energy costs as you can quickly heat each room from the reception within less than one hour.
Can I use the IREWA carbon underfloor heating in my Tinyhouse or boat?
Of course, we from IREWA have a lot of experience heating up places where every inch counts.
Can I put the IREWA carbon underfloor heating in single rooms like my yoga studio?
Yes, you can upgrade each room step by step.
Is a bigger effective heating surface better than a smaller one?
Yes, because the bigger the effective heating surface, the quicker your room warms up and the less time the heating needs to run.
How is the patented IREWA structure beneficial?
The patented IREWA structure reduces heat loss in the ground, reduces warm-up times and reduces your consumption costs considerable.
Is a full surface carbon coating better than a part surface coating?
Yes, because heated air can escape quicker than heated surfaces. For more details, see IREWA’s technical data.
Is IREWA carbon underfloor heating suited for allergic people?
Yes, since dust is no longer stirred up, the excrement of house dust mites is no longer stirred up and allergy sufferers can finally breathe freely in winter.
Less cleaning with IREWA carbon underfloor heating?
Yes, less stirred up dust means less dust to clean.
Is the IREWA carbon underfloor heating more effective than radiators?
Yes, because heated air can escape quicker than heated surfaces.
Can I combine IREWA with a photovoltaic system?
Yes, the IREWA carbon heating system and a photovoltaic system are the ideal combination, as you can use more electricity than you produce and are less affected by price fluctuations.
Has IREWA carbon underfloor heating the highest quality carbon heating element on the market?
Yes, because we from IREWA use better materials and a more complex production process to provide a longer lasting heating system with less consumption costs than competitors. TÜV is another indicator for our supreme quality.
