Outdated Product
Gas heating boiler of increased power. The model uses two circulation circuits, due to which it can provide heating and hot water supply in the manned room. Thermal power is adjusted in the range of 2.7-21 kW. The potential of the device is enough to efficiently heat an object with an area of up to 168 m². The closed combustion chamber uses turbocharging. The furnace uses IoniDetect technology, which allows you to generate heat while minimizing gas consumption. The heat carrier can be heated within 30-85 °C, and the heating limit of the hot water supply system is 65 °C. The heating circuit works under pressure up to 3 bar, the system is equipped with a built-in circulation pump. The gas heating boiler Vaillant ecoTEC plus VUW 26CS/1-5 is equipped with a built-in programmer. If necessary, a...remote control module can be connected to the device, which will allow diagnosing and configuring the operation of the heating system via the Internet, using any computer device, tablet or smartphone. This boiler has an incredibly high efficiency. Thanks to the condensing system of the furnace, additional heat is generated, which makes heating 10-15% more efficient.
