Viessmann Vitopend 100-WH1D258 is a double-circuit gas boiler with a useful power of 23 kW, which can provide efficient heating (area up to 172 m2), as well as constant hot water supply (capacity 11 L / min Δt=25 °C). The average efficiency of the installation is 90%, which in general can be called a classic indicator for gas non-condensing boilers. The control panel is equipped with a display, the automation includes a special summer mode of operation (without heating), but the installation itself also needs to be connected to the power supply. Let's pay attention to the open combustion chamber, because of which the device needs to be connected to the chimney.
