Renovation

The renovation yard is opened during the month of September 2011.  We begin with the roof remake: all rafters replacement, boarding, laying sheaths and, at the end, the “lose” (slates), mostly still the original ones.  Autumn is particularly favorable and dry so that works proceed without great difficulties.  On the southward pitch we decide to install integrated panels in order to feed a solar thermal system so as to balance existing heating and hot sanitary water systems.  5 IDMK25-AL recessed in the roof panel collectors are positioned (see pdf) they will stockpile through coil Comfort PSR800 (see pdf) (Sonnenkraft material [see home page]). Each panel has a 2,52 m² gross surface and a 252 kWh/(m²a) standard radiant efficiency for a 12,60 m² total surface and a 2625 kWh/(m²a).  The roof will be finished by mid November, after the one only short rainy period in the whole autumn.
