On the one hand, Vaillant ecoTEC plus VU INT 386/5-5 is a single-circuit boiler, that is, designed exclusively for providing space heating, without hot water supply. On the other hand, the manufacturer provides for the possibility of connecting an indirect heating boiler, and a special summer operation mode was initially implemented. But the main feature of the device is, of course, an efficiency of 108%, which makes the model a very effective solution. Useful power of 35 kW is enough to install the device in a room up to 280 m2. The control panel has a display and a clear control interface. The maximum temperature in the heating system is 85°C, the operating pressure in the heating circuit is 3 bar, in the DHW circuit it is up to 10 bar.
