Vaillant ecoTEC plus VU INT 246/5-5 20 kW
 | Outdated Product 36 600 ₴ Highly efficient double-circuit gas boiler with the condensing principle of heat transfer. Compared to classic double-circuit boilers, it has higher energy efficiency and is able to save gas consumption by 7-8%. It is distinguished by the presence of an additional stage of flue gas cooling, which makes it possible to use the heat of condensation of water vapor formed during the combustion of fuel. It is also equipped with a modulating burner with an extended power control range (from 20 to 100%), which further increases the flexibility and efficiency of using natural gas. High-quality chromium-nickel stainless steel is used as the heat exchanger material. Electronic control of the heating boiler Vaillant ecoTEC plus VU INT 246/5-5 has an informative display and an intuitive interface. It i...s possible to connect an external thermostat-programmer, which is purchased separately. The boiler provides fast heating of the hot water circuit (maximum temperature 65 °C) and is capable of producing up to 11 L/min of heated water (at a temperature difference of 30 °C). Forced flue gas extraction and a low-noise circulation pump make it possible to install the unit directly in a residential area. Equipped with all necessary protective systems, including frost protection. Made in Germany, backed by a proprietary 2-year warranty. |

We bought such a boiler for heating a small sports complex. Works for two small gyms plus changing rooms and showers with a total area of about 300 square meters. They also didn’t strain it with hot water; for this, they purchased a separate boiler. I will add that, now in our market there is not such a large selection of powerful and highly efficient condensing boilers to sort through. But the fact that we managed to pick up a boiler of such a well-known and reliable brand as Vaillant was frankly pleased. First of all, power. The heating area is serious, not every wall-mounted boiler can handle it. This one copes easily and without straining, even in severe frosts. High efficiency. I specifically wanted to purchase a modern boiler that uses the heat of condensation of water vapor from the products of gas combustion. According to conservative estimates, thanks to this boiler, we save about $ 70-80 per month on gas. Not bad, agree. Good automation, which accurately fulfills the set temperature. It controls the amount of gas and air supplied to the burner, and the boiler continues to work even at low pressure in the gas line. Safe. There are many protective systems for all occasions. Expensive. There was even an idea to buy something simpler, but drove it away in time. Now I understand that the money was not spent in vain - one saving on gas is worth something. Without a voltage stabilizer, it turned off from time to time. They measured it, it turned out that the voltage sank to 160-170 volts. The stabilizer works flawlessly. use Vaillant ecoTEC plus VU INT 386/5-5 month or more |
