Nejprve by bylo vhodn\u00e9 zjednodu\u0161en\u011b popsat, co je to samoregula\u010dn\u00ed topn\u00fd kabel a jak funguje. Samoregula\u010dn\u00ed topn\u00fd kabel je elektrick\u00fd kabel, kter\u00fd se stejn\u011b jako klasick\u00fd odporov\u00fd topn\u00fd kabel za\u010dne p\u0159i pr\u016fchodu elektrick\u00e9ho proudu zah\u0159\u00edvat. Zat\u00edm co ale odporov\u00fd topn\u00fd kabel top\u00ed st\u00e1le stejn\u00fdm v\u00fdkonem, samoregula\u010dn\u00ed topn\u00fd kabel je schopen m\u011bnit sv\u016fj topn\u00fd v\u00fdkon v z\u00e1vislosti na teplot\u011b ve kter\u00e9 se nach\u00e1z\u00ed. V praxi to znamen\u00e1, \u017ee \u010d\u00edm vy\u0161\u0161\u00ed teplota na kabel p\u016fsob\u00ed z jeho p\u0159\u00edm\u00e9ho okol\u00ed, t\u00edm ni\u017e\u0161\u00ed tepeln\u00fd v\u00fdkon kabel vyprodukuje a naopak. Tato v\u00fdkonov\u00e1 charakteristika je v\u00edcem\u00e9n\u011b line\u00e1rn\u00ed s klesaj\u00edc\u00ed tendenc\u00ed p\u0159i vzr\u016fstaj\u00edc\u00ed teplot\u011b. Kabely pak rozli\u0161ujeme z hlediska m\u011brn\u00e9ho v\u00fdkonu. Z\u00e1kladn\u00edmi \u0159adami jsou kabely o v\u00fdkonech 10, 15, 25 W\/m ud\u00e1van\u00fdch p\u0159i 10\u00b0C. V\u00fdhodou t\u011bchto kabel\u016f je pou\u017eit\u00ed v libovoln\u00fdch d\u00e9lk\u00e1ch (omezeny jsou pouze maxim\u00e1ln\u00ed pracovn\u00ed d\u00e9lkou) a v\u00fd\u0161e zm\u00edn\u011bn\u00e1 mo\u017enost \u00fapravy topn\u00e9ho v\u00fdkonu za z\u00e1klad\u011b okoln\u00edch teplot. D\u00edky samoregula\u010dn\u00edmu efektu se tyto kabely nemohou vlastn\u00ed produkc\u00ed topn\u00e9ho v\u00fdkonu p\u0159eh\u0159\u00e1t a to ani p\u0159i vz\u00e1jemn\u00e9m doteku \u010di k\u0159\u00ed\u017een\u00ed. Toho se vyu\u017e\u00edv\u00e1 p\u0159edev\u0161\u00edm p\u0159i ochran\u011b a oh\u0159evech potrub\u00ed, kde je pou\u017eit\u00ed t\u011bchto kabel\u016f t\u00e9m\u011b\u0159 nutnost\u00ed. Tyto vlastnosti se tedy mohou zd\u00e1t na prvn\u00ed pohled ide\u00e1ln\u00ed i pro podlahov\u00e9 vyt\u00e1p\u011bn\u00ed, skute\u010dnost je v\u0161ak trochu jin\u00e1.<\/p>\n\n\n\n

Dal\u0161\u00edm v\u00fdznamn\u00fdm faktorem hraj\u00edc\u00edm proti samoregula\u010dn\u00edm kabel\u016fm jsou jejich vysok\u00e9 startovac\u00ed proudy.

Ve skute\u010dnosti v\u0161ak nam\u011b\u0159en\u00e9 hodnoty startovac\u00edho proudu byly mnohem vy\u0161\u0161\u00ed. P\u0159i sepnut\u00ed topen\u00ed cca po t\u0159ech dnech ne\u010dinnosti, kdy byla teplota v m\u00edstnosti 21,5\u00b0C byl nam\u011b\u0159en startovac\u00ed proud 20A! Tento proud sice rychle kles\u00e1, ale pokles na dodavatelem uvedenou hodnotu 10A trv\u00e1 zhruba 60s. Ust\u00e1len\u00ed proudu na provozn\u00ed hodnotu okolo 4A pak trv\u00e1 n\u011bkolik minut. Za tuto dobu je sp\u00ednac\u00ed kontakt termostatu zna\u010dn\u011b tepeln\u011b nam\u00e1h\u00e1n a postupem \u010dasu doch\u00e1z\u00ed k jeho zni\u010den\u00ed.
