Combined condensing gas boiler
The condensing combined gas device ecoTEC plus VUW, popularly called the gas combined boiler, is intended for space heating and preparation of domestic hot water.
The “plus” series of this device is an upgrade of the “pro” series for more complex requirements with a wider range of performance
State-of-the-art “Made in Germany” condensing technology combines reliability and quality with a distinctive Vaillant design and ease of operation. Thanks to the so-called “ELGA” function, the combustion process is constantly monitored and controlled. If the deviation is greater than allowed, the electronics will independently correct the air or gas supply and thus ensure the maximum degree of efficiency.
ecoTEC plus combined devices are available in versions from 20 kW to 30 kW. Thanks to the integrated secondary exchanger of 19 lamellas, the device can work not only on heating but also on the preparation of domestic hot water. It is important to emphasize that thanks to the “Aqua Power Plus” function, the device works with an additional power of 21% when preparing hot water, which means even greater comfort.
High-efficiency pumps save money
The price of fuel actually consumed is not the only factor affecting the running costs (operating costs) of the heating system. The electricity used by the system is also part of the cost of the electricity bill. In terms of the various components that make up the system, the pump consumes by far the most power. Therefore, we have developed a high-efficiency pump (energy efficiency class A). The pump continuously adapts to the needs of the heating system, thus reducing the electricity consumption of the heating system by as much as 70%. Lower running costs save you money, while at the same time improved energy efficiency helps preserve the environment.
eBUS interface for easy connection of system components
The eBUS communication interface allows you to interconnect different units within a home heating system. The flexible design of the eBUS interface allows the system to be upgraded and expanded with minimal effort. This means that the system monitors technological progress and keeps your investment far in the future.
Aqua-Power-Plus for optimal hot water temperature
Ensuring a sufficient amount of hot water requires a larger capacity from the heating device than is required for heating. This is why a higher performance device is often installed. In response to this, the Aqua-Power-Plus system has been designed to provide as much as 21% more capacity during peak hot water consumption. This means you can enjoy the optimal amount of hot water with less heating device performance. This can help reduce your bill as well as preserve the environment.
Digital information-analytical (DIA) system
Reduced reflection requirements and longer service life thanks to a wide range of modulation
The modulation range is the boundary between the maximum and minimum performance of the heating device. With a wide range of modulation, Vaillant’s heating device works quietly and steadily, while ensuring the necessary optimal heating of your home. Modulation also significantly reduces the number of on / off cycles, resulting in lower carbon emissions. In addition, the components are protected from unnecessary wear, which significantly reduces the maintenance costs of your device.
Setting for hot water
Vaillant certified air / flue system
Stainless steel heat exchanger
The heat exchanger located inside our condensing heater is made of stainless steel. High-quality and durable metal combined with our excellent design ensures that the heat exchanger will be protected against corrosion for a long time. This increases the longevity of your device and ensures a reliable and efficient device today and in the future.
AquaComfort Plus system for optimal hot water supply
Vaillant the combined heating and hot water system with the built-in AquaComfort Plus system stores an additional amount of hot water that is ready when you need it. So, whether you are bathing or showering, you can have confidence that our combined water heater will provide hot water that is heated to a constant temperature – without the need to wait!
