Vaillant ecoTEC plus VUW INT 246/5-5 21.7 kW (0010021965)
 | Outdated Product $1,399.26 up to $1,652.18 Vaillant ecoTEC plus VUW INT 246/5-5 is a fairly advanced gas boiler that can provide both efficient space heating and constant hot water supply. The useful power of this modification is 24 kW, the manufacturer recommends using it for rooms up to 192 m2. Closed combustion chamber, maximum hot water temperature — 65°C, a special summer mode of operation is provided, the operating power is adjustable in the range of 20-100%. However, the main advantage of the model is that it is a condensing boiler — the average efficiency for the heating season is 108%. A classic set of necessary protection systems has also been implemented. |

150 years of experience and tradition
The German company, which has been specializing in products for heating and hot water supply for almost a century and a half, offers in this segment an advanced double-circuit boiler Vaillant ecoTEC plus VUW INT 246/5-5, which completely solves the problem of providing heat to residential and non-residential premises with an area of 174 m2. The device is suitable both for installation in new buildings under construction, and for installation in reconstructed premises. The manufacturer assures that the heater, subject to the rules of installation and operation, will last at least 10 years. This is a 21.7 kW wall-mounted model with a closed combustion chamber, capable of operating in summer (hot water only) and winter (heating + DHW) mode. The device, in addition to direct combustion of fuel, uses the latent thermal energy of gas condensate, allowing you to get an average efficiency of about 108% for the heating season. The maximum temperature in the heating circuit is 85 °C and hot water can be heated up to 65 °C.
Low NOx content in the "exhaust"
The model is equipped with a modulating gas burner with a power adjustment range of 20 – 100%. The electronic pre-mixing system automatically prepares the optimal proportion of gas and air, which ensures a low NOx content (up to 20 mg/kWh) in the combustion residues. The heating unit is equipped with a stainless steel primary heat exchanger, a DHW plate heat exchanger and a 2-stage circulation pump. In addition, the device received a complete set of hydraulic piping elements, including a siphon for collecting gas condensate and an expansion tank of 10 liters. An integrated security system controls the continuous burning of the flame, monitors the pressure of gas and coolant, and also monitors critical temperatures (protection against overheating and freezing) and draft in the exhaust duct.
Compatible knobs for advanced control
Thanks to the built-in eBus communication bus, the device has the ability to connect a remote control unit. In addition, it can optionally be supplemented with compatible controllers that expand the control and monitoring of heating and DHW systems. So the wall-mounted room thermostat VRT 50 with a display solves the problem of controlling the boiler plant by the room temperature, and the eRELAX controller with the eBus bus allows local and remote control of the boiler via the Internet. The automatic weather-compensated heating controller multiMATIC VRC 700/6 is used for the integrated control of the entire heating system with support for 9 heating circuits, while the more sophisticated controller auroMATIC 620 is designed to control a heating system with solar collectors and can support systems with 12 heating circuits. The capabilities of the heating boiler amaze and impress just like the “space” price for it. But there's nothing you can do about it — high technologies cost a lot.
