Floor-standing condensing boiler VKK 476/4 ecoVIT exclusive 0010007522

High Performance in Large Heating Systems

A unit with a rated power of 46.8 kW (in the 50-30°C range) is a solution dedicated to larger single-family homes and multi-family buildings where standard wall-mounted boilers cannot meet the heating demand. Thanks to the use of modern condensing technology, the unit's efficiency reaches 108% (at partial load), translating into real gas consumption savings compared to older boiler generations. The high water capacity of approximately 100 liters acts as a natural thermal buffer. This is a key feature for installers – it allows for temperature stabilization in the circuit and reduces the number of burner start-up cycles, extending the service life of the entire drive assembly and ensuring a comfortable, shock-free indoor climate.

Installation Comfort and System Flexibility

For professionals, installing this boiler is significantly simpler than with many competing floor-standing units. The design does not require an additional hydraulic separator or a bypass valve, simplifying the hydraulic system and reducing installation costs. Prefabricated piping and dedicated kits for charging the domestic hot water (DHW) tank enable quick system connection. Special attention should be paid to the Aqua Condens system – thanks to it, the boiler achieves a high efficiency coefficient even during DHW preparation. Two separate return connections allow for maintaining low temperatures in the lower part of the heat exchanger even during intensive DHW tank charging, which is crucial for the efficiency of the condensation process.

Application and Operational Parameters

The unit is ideally suited as the primary heat source in heating systems with an area ranging from 100 to 700 m². Its power modulation (range from 13.7 to 46.8 kW) allows for precise matching of burner operation to the building's current demand, which is particularly important when operating in conjunction with solar installations or heat pumps in hybrid heating systems. Low flue gas emissions and quiet operation mean the boiler can be installed even in residential rooms (in accordance with standards for sealed combustion chambers). The unit dimensions are 1257 mm in height, 570 mm in width, and 691 mm in depth, and a mass of approx. 120 kg requires appropriate preparation of the base and space in the boiler room, but its compact shape facilitates transport and placement in standard technical rooms.

Key Operational Benefits:

• Energy Savings: Efficiency of approx. 108% at partial load significantly reduces gas bills.
• Operational Stability: Large water capacity (approx. 100 l) eliminates frequent burner cycling, protecting against overheating and mechanical wear.
• Versatility: Ideal for upgrading old installations as well as new systems with high heat demand.
• Easy Servicing: Simple hydraulic design without unnecessary intermediate components facilitates diagnostics and repairs.

This boiler combines a robust metal construction with advanced electronics controlling the combustion process. Thanks to this, the unit not only heats the home efficiently but also cares for the environment by minimizing the emission of harmful substances. It is a choice for those seeking a reliable heat source for years, without the need for constant interventions in the heating system.
