Realizovan\u00e9 \u0159e\u0161en\u00ed<\/h2>\n\n\n\n

Nov\u00fd zdroj tepla tvo\u0159\u00ed dva automatick\u00e9 kotle ETA eHack<\/a>, ka\u017ed\u00fd s v\u00fdkonem 180 kW. \u0158ada pokr\u00fdv\u00e1 rozsah od 20 do 240 kW, tak\u017ee dvojice 180 kW pokryje odb\u011br su\u0161\u00e1ren s rezervou. Dva zdroje m\u00edsto jednoho nav\u00edc znamenaj\u00ed, \u017ee provoz nez\u016fstane bez tepla ani tehdy, kdy\u017e se na jednom kotli pracuje.<\/p>\n\n\n\n

Palivo jde ze sila p\u0159\u00edmo do meziz\u00e1sobn\u00edku, kter\u00fd jsme doplnili mezi silo a kotelnu. Odtud jde do ka\u017ed\u00e9ho kotle samostatn\u011b. U dvou kotl\u016f to hraje roli \u2013 oba maj\u00ed palivo i tehdy, kdy\u017e silo dopravuje nerovnom\u011brn\u011b.<\/p>\n\n\n\n
