... heat exchange area, and self-cleaning through thermal expansion. The VTA/N-1 model includes a carbon steel heat exchanger at the bottom for optional connection to solar collectors or other heat sources (heat pump, gas, solid fuel, electric boilers). The VTA/N-2 model lacks a heat exchanger, allowing direct connection to any heat generator. The VTA/N-1-SOLAR PLUS model has an enlarged inner tank partially placed within the heat exchanger, improving efficiency with low-temperature heat sources.
