Nejv\u00edce je zastoupeno smrkem, borovic\u00ed a mod\u0159\u00ednem. Kdy\u017e ho\u0159\u00ed, kr\u00e1sn\u011b von\u00ed, ale bohu\u017eel je jeho v\u00fdh\u0159evnost ni\u017e\u0161\u00ed ne\u017eli u d\u0159eva tvrd\u00e9ho.Tvrd\u00e9 d\u0159evo je pak ze strom\u016f listnat\u00fdch a nejv\u00edce je zastoupeno dubem bukem, a habrem. Do krbu se hod\u00ed v\u00edce, proto\u017ee ho\u0159\u00ed pomaleji a hlavn\u011b „neprsk\u00e1“. Ale tak\u00e9 nevon\u00ed. A h\u016f\u0159e se zapaluje. Prost\u011b si mus\u00edte vybrat, co v\u00e1m l\u00e9pe vyhovuje. Dal\u0161\u00ed v\u011bc, kter\u00e1 bude jist\u011b majitel\u00e9 krb\u016f a kamen zaj\u00edmat je v\u00fdh\u0159evnost d\u0159eva.

D\u0159evo m\u00e1 v\u00fdh\u0159evnost velmi n\u00edzkou, snad nejhor\u0161\u00ed z ho\u0159lav\u00fdch materi\u00e1l\u016f. Dokonce men\u0161\u00ed ne\u017e pap\u00edr.

Co\u017e je ov\u0161em z\u00e1visl\u00e9 i od vlhkosti (to hlavn\u011b) a dal\u0161\u00edch faktor\u016f. P\u0159esn\u00e9 cifry lze velmi lehce dohledat na internetu. Pocitov\u011b to asi norm\u00e1ln\u00ed \u010dlov\u011bk, sed\u00edc\u00ed u krbu nepozn\u00e1. Jen nam\u00e1tkou zvol\u00edm na uk\u00e1zku dva druhy. Jako prvn\u00ed dub – tvrd\u00e9 d\u0159evo, v\u00fdh\u0159evnost 11,05 GJ\/m3, siln\u00e1 k\u016fra, a jako druh\u00fd topol – m\u011bkk\u00e9 d\u0159evo, v\u00fdh\u0159evnost 6,54 GJ\/m3, st\u0159edn\u011b siln\u00e1 k\u016fra. Jehli\u010dnany zde nap\u00ed\u0161i jen v\u0161eobecn\u011b – v\u00fdh\u0159evnost 7,35 GJ – 9,25 GJ\/m3, st\u0159edn\u011b siln\u00e1 k\u016fra. Jak vidno, \u0161k\u00e1la je \u0161irok\u00e1. Mo\u017en\u00e1 dal\u0161\u00ed aspekt, kter\u00fd v\u00e1s bude zaj\u00edmat je popelnatost. N\u011bjak\u00fd obrovsk\u00fd rozd\u00edl zde nehledejme.

A zcela jist\u011b je nejd\u016fle\u017eit\u011bj\u0161\u00ed polo\u017ekou cena.
