Floor-standing condensing boiler with integrated stratified buffer tank VSC 206/4-5 90 ecoCOMPACT 0010014677

High Efficiency and Hot Water Comfort in a Single Housing

This device combines the functions of a modern condensing boiler and an efficient hot water storage tank, eliminating the need to install additional tanks in the boiler room. Thanks to the use of condensing technology, the boiler recovers heat from water vapor contained in flue gases, achieving a nominal efficiency of 108% in heating mode and 102% during domestic hot water preparation. This level of performance translates into real energy savings – compared to traditional conventional boilers, gas consumption can drop by up to 30%.

A key structural element is the built-in stratified storage tank with a capacity of 90 liters. The use of direct stratified charging allows for more efficient energy utilization than in traditional tanks with coils. In practice, this means that the 90-liter tank of this model offers an initial hot water output (244 liters within 10 minutes with a temperature drop of 30K) comparable to conventional tanks with significantly larger capacities. For the installer, this represents a significant logistical advantage – the device occupies less space, while for the end user it guarantees a stable flow of hot water even when drawing from multiple points simultaneously.

Application and Installation Flexibility

The device has been designed with single-family housing in mind, where space saving while maintaining high user comfort is a priority. Compact dimensions (height 1320 mm, width 599 mm, depth 693 mm) allow installation even in small boiler rooms or technical rooms. The housing features an aesthetic design that was awarded the IF Design Award in 2014, making it a visually attractive interior element.

Thanks to a wide power modulation range (from 4.3 kW to 21.5 kW), the boiler perfectly adapts to the building's heat demand. It is versatile in application – suitable for both underfloor heating installations and traditional radiator systems. The device operates on natural gas (GZ-50, GZ-41.5, GZ-35) and propane, increasing its flexibility depending on fuel availability at a given property.

Key Features and Operational Benefits

Below are the most important technical and user aspects of this model:

• Aqua Condens System Technology: Utilizes the condensation effect also during domestic hot water heating, increasing the overall efficiency of the device and reducing operating costs.
• Stainless Steel Heat Exchanger: The built-in tubular heat exchanger made of stainless steel ensures high corrosion resistance and long-term trouble-free operation.
• Space Saving: Combining the boiler and storage tank in a single housing eliminates the need to install an additional buffer tank or external boiler.
• High Energy Class: The device has an energy class A for both heating purposes and domestic hot water preparation (XL load profile).
• Easy Service: The COMPACT type construction facilitates access to key components during periodic inspections by the service technician.

The device dimensions are 1320 mm in height, 599 mm in width, and 693 mm in depth, allowing free placement in a standard boiler room. The rated power for a temperature difference of 50-30°C reaches up to 21.5 kW, ensuring sufficient performance for single-family homes with varying heat demands. The device efficiency exceeds 100% thanks to condensate heat recovery, and the capacity of the built-in stratified storage tank is approximately 90 liters. Thanks to this solution, installers gain a device ready for quick "turnkey" installation, while investors receive a heating system with high energy efficiency without the need to occupy additional space for external storage tanks.
