Buffer tanks of series VTA are used in conjunction with different heat supply sources (boilers – solid fuel, gas, electric, solar collectors, heat pumps) for accumulating of heat and its use for heating and hot water supply (HWS). Construction of heat accumulators of series VTA provides the presence of heat exchanger made of stainless and carbon steel, and flange and the ability to install thermoelectric heating elements.
Stainless steel heat exchanger, which is used in models VTA-1, VTA-2, constructively is located in the upper part of the tank and is designed to prepare domestic hot water.
Carbon steel heat exchanger, which is used in models VTA-1, VTA-3, constructively is located at the bottom of the tank. This heat exchanger is designed for use in conjunction with solar collectors or low-temperature heating systems.
