A study commissioned by the Eu-Ray, shows that the energy saving that can be obtained from a system of floor heating, Ranges from a 8% up to a 30%.
And 'well known that this type of system is much more efficient but now we have confirmation.
The published study was conducted by the University of Copenhagen (DK) and Padua.
This study compared three different buildings (a detached house, an office and a factory) located in three different areas (Venice, Brussels and Stockholm), comparing the energy and emissions Co2 depending on the use of radiators or floor heating.
The results clearly demonstrate that l 'underfloor heating saves dall'8 to 30%. More details are available at www.eu-ray.com.
One of the graphs compare the percentage of primary energy used by the three buildings.
For each area, there are three columns corresponding to the low-temperature radiators (50 ° C) * and the other three floor heating, The gray columns show the primary energy used when the system is powered by a gas condensing boiler (Boiler), the green-blue indicate what happens with a heat pump air (AW HP) while, the yellow, consider the use of a geothermal heat pump (GSHP).
With underfloor heating, the amount of energy used is lower and, using a heat pump, the savings are high, and this is significant because, in the future, to reduce fossil fuels, we should go to heat pumps.
* The comparison was made with radiators dimensioned sent to 50 ° C. Usually plants with temosifoni are designed with flow temperature to 65-70 ° C. This means that the energy savings achievable in practice with a floor system is much higher.
