First of all, the model stands out for its efficiency — the average efficiency of the Vaillant ecoTEC pro VUW INT 236/5-3 gas boiler for the heated season is 107%. It was possible to achieve such a high figure thanks to the condensing technology, which provides additional energy from the condensation of water vapor. The useful power of the model is 23 kW, in other words, this unit can serve as a good solution for heating a room up to 184 m2. The model is double-circuit, that is, the user can also count on constant hot water in the tap. And for the summer period, you can completely turn off the heating as unnecessary, but simply use the boiler to prepare water.

Products under the Vaillant brand have gained well-deserved popularity among heating equipment due to their high quality and reliability. Therefore, it is not surprising that the Vaillant ecoTEC pro VUW INT 236/5-3 condensing boiler is in demand among the most diverse audience.

Two contours

The model is suitable for installation in houses up to 184 m² — this is the figure that the efficient operation of the heating circuit is designed for. The primary heat exchanger is made of high quality stainless steel, and the heat carrier temperature range can vary from 30°C to 85°C. The hot water circuit has a lamellar design, and the material of its execution is food grade stainless steel. Water is heated in it to a temperature of 30-60°C.

Exploitation

The boiler is equipped with a closed combustion chamber with forced removal of flue gases through a coaxial chimney with a pipe diameter of 60/100 mm (included in the delivery). Combustion air intake can be carried out by the model both from the premises and from the street. The Vaillant ecoTEC pro VUW INT 236/5-3 uses natural or liquefied gas as an energy source.

Comfortable microclimate

Everyone will be able to understand the management of the boiler, which is facilitated by an intuitive menu interface and a clear display of information on the built-in backlit display. The screen also serves to display an error code in case of malfunctions or errors in the operation of the device. Although you don’t have to worry about the appearance of problems with the boiler, since a whole set of various security systems protects it from adverse factors. Under their vigilant control, the creation of a comfortable temperature regime in the dwelling and its uninterrupted maintenance on an ongoing basis is ensured, saving energy consumption.
