Gelijkwaardigheidsverklaring HSI

HSI has commissioned engineering consultants Peutz to draw up an attestation of equivalence in conformity with the NEN7120 standard. Their research concludes that the HSI floor heating is up to 60% more efficient in comparison to traditional underfloor (water) heating, justifying the related
output yield of 1.5 ȠH;em.

The attestation of equivalence has been listed in the ISSO database.
