 | Expecting restock 35 800 ₴ Single-circuit heating gas boiler of condensing type. The main distinguishing feature of this model, of course, is the highest efficiency, due to the use of the condensing principle of extracting heat from natural gas combustion products. Unlike conventional boilers, hot flue gases undergo deeper cooling, which makes it possible to extract from them the latent heat of condensation of water vapor generated directly in the combustion process. Thanks to this engineering solution, this condensing boiler is 7% more economical than conventional design units. It has a closed-type combustion chamber and forced exhaust of flue gases, which allows it to be mounted in residential areas.

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 |
Economical gas boiler for an apartment
Vaillant ecoTEC plus VU INT 166/5-5 has a fairly modest heat output of 14 kW. Therefore, it is designed not so much for private houses as for apartments. This unit can heat rooms up to 112 m². It, like other boilers with a closed combustion chamber and forced gas exhaust, can be installed in residential areas. It is only necessary to comply with all the requirements necessary for the installation of condensing boilers. They consist in the presence of a socket, a coaxial chimney, as well as the ability to connect the device to the sewer to drain condensate.
Reliable performance and easy operation
“Under the hood” of this boiler is a durable stainless steel heat exchanger, a 10 liter expansion tank, a two-stage circulation pump, three-way valves and a built-in siphon. Access to the "insides" for their maintenance is carried out from the front, so the boiler can be installed even in a corner, even in a niche. Automation deftly controls the modulating burner, which can change the power in the range from 20% to 100%. Therefore, the boiler easily adapts to changing loads and adapts to different weather conditions. It is equipped with protective systems for all occasions and is completely safe. Therefore, even those who are not friends with technology will feel calm.
Heating without the hassle
Thanks to modest technical characteristics, Vaillant ecoTEC plus VU INT 166/5-5 consumes little gas — less than 1.7 m³ / h when operating at full capacity. But it should be noted that the ratio of price and power is far from being the most favorable. The fact is that Vaillant is considered a “premium” brand. Heating boilers of this brand are distinguished by high reliability of all components and assemblies and well-coordinated work of mechanics with electronics, thanks to which the equipment works like clockwork. This is why Vaillant condensing boilers have a long service life and are trouble-free.
