The same water towel dryer – heat carrier – water (oil, antifreeze) + steel, only additionally it is necessary to buy a heating element (often at sale managers do not specify it, and on a photo design-radiator, as a rule, is shown without it). After the time on TEN the scale forms, it is necessary to service it, the towel dryer can start to leak. At the same time initially TEN is a very expensive pleasure. It consumes a lot of electricity – in heating mode on average 500 W/h, the principle of work, as at the boiler, only the heat is distributed unevenly (at the bottom of the towel dryer the temperature is much higher, as there is no circulation of liquid). In short – it’s just a pipe with water, with very low heat output, devouring electricity. The day before yesterday. Approximately like an old URAL car with consumption of 100l/100 km, only with a more modern and attractive cabin for the driver, but with the same engine.
