\nPre\u010do vetracie jednotky v zime zam\u0155zaj\u00fa\n<\/h2>
\nV zime odpadov\u00fd vzduch pr\u00fadiaci cez v\u00fdmenn\u00edk tepla odovzd\u00e1va svoje teplo \u010derstv\u00e9mu vzduchu a ochladzuje sa. V siln\u00fdch mrazoch sa odpadov\u00fd vzduch ochlad\u00ed na \u00farove\u0148, pri ktorej sa vo v\u00fdmenn\u00edku vytvor\u00ed kondenz\u00e1t (rosn\u00fd bod).

Pokia\u013e je teplota \u010derstv\u00e9ho vzduchu nad nulou, kondenz\u00e1t jednoducho odtek\u00e1 z vetracej jednotky. Len \u010do v\u0161ak \u010derstv\u00fd vzduch zamrzne, namiesto kondenz\u00e1tu sa vytvor\u00ed n\u00e1mraza. Zmrznut\u00fd kondenz\u00e1t postupne upch\u00e1va v\u00fdmenn\u00edk tepla a pri dlh\u0161ej prev\u00e1dzke by ho mohol roztrhn\u00fa\u0165.\n<\/div>

    \nAko funguje predhrievanie\n<\/h2>
    \nElektrick\u00e1 vyhrievacia \u0161pir\u00e1la je najbe\u017enej\u0161ou ochranou proti \u00farazu elektrick\u00fdm pr\u00fadom. Je 100% funk\u010dn\u00e1 a \u013eahko sa ovl\u00e1da. Hlavnou nev\u00fdhodou je spotreba elektrickej energie: pre dom je be\u017en\u00fd v\u00fdkon predohrevu 1500 W. \u017diadne porovn\u00e1vacie tabu\u013eky t\u00fato spotrebu nezoh\u013ead\u0148uj\u00fa!

    Odhliadnuc od pe\u0148az\u00ed, ktor\u00e9 sa sp\u00e1lia pri predk\u00faren\u00ed, jeho spotreba v\u00fdrazne ovplyv\u0148uje energetick\u00fa bilanciu n\u00edzkoenergetick\u00e9ho domu. Ak dom vyu\u017e\u00edva fotovoltaick\u00fa v\u00fdrobu elektriny a bat\u00e9riov\u00e9 \u00falo\u017eisko, predhrievanie v\u00fdrazne skracuje \u010das\u0165 noci, ke\u010f je dom nez\u00e1visl\u00fd.\n<\/div><\/div>\n<\/section>
