The Vaillant atmoTEC pro VUW model is a double-circuit wall-mounted gas boiler for heating and hot water supply.
It is reliable and productive. A new burner made of chromium-nickel steel, a scale-resistant plate heat exchanger, a closed expansion tank and other elements introduced into its design are designed for long-term and active operation in almost any conditions. The boiler is equipped with permanent frost protection and an intelligent system for monitoring the water pressure level in the system. The installed winter/summer mode switch allows you to extremely reduce fuel costs outside the heating season.
Thanks to the electronic ignition system, as well as combustion control and an adjustable nozzle, the model’s boiler consumes gas with maximum efficiency and is highly efficient, reaching 91%. It is installed in boiler rooms of residential buildings and outbuildings in low-temperature radiator heating systems. This model is not intended for use in cascade systems.
