Example for a newly built single-family home of 120 m2 in Barcelona
Below, we present a study of the consumption of the radiant foil system for a newly built 120 m2 single-family home in Barcelona, prepared by Cecather technicians.
- Studio power: 4.8 Kw
- Total power to hire: 6.9 Kw
- Heating use: 704 hours/year
- Estimated consumption of the radiant sheet: 3,377.66 kWh/year
The installation of Cecather® underfloor heating (TDH Hourly Discrimination Rate. Rate of: €0.14583/kw) would result in an expense of €492.50 /year. In other words… 2.74 euros per day. (Note.- This study has been carried out considering the worst external thermal and operating circumstances).
Example for a 70m2 flat in Barcelona
This study has been carried out considering poor insulation and an outside temperature of 1ºC. These results are considered when all heating is running during the six winter months (180 days). Heating operation at 21ºC is also considered, remembering that each degree that drops below 21ºC reduces consumption by 7%.
- Studio power: 5.6 Kw
- Total power to hire: 6.9 Kw
- Heating use: 704 hours/year
- Estimated consumption of the radiant sheet: 3,940.61 kWh/year
Installation of Cecather® underfloor heating (TDH Hourly Discrimination Rate. Rate: €0.14583/kw) the result is an expense of €574.58 /year. In other words, 3.19 euros per day.
Under normal winter and operating conditions we can consider a saving in consumption between 20/25 % on what is written.
