Vaillant Condensate Hose 0020244429

Vaillant Condensate Hose 0020244429

The Vaillant Condensate Hose (Part No. 0020244429) is a genuine part designed to safely transport acidic condensate from the boiler's secondary heat exchanger to the internal trap. This flexible, high-durability hose is engineered to withstand the corrosive nature of the condensate produced during the combustion process, ensuring a leak-free path to the drainage system.

Key Features and Specifications
Corrosion Resistant: Manufactured from a specialized polymer designed to resist the acidic levels found in the condensate of high-efficiency boilers.

Flexible Design: Allows for easy routing within the compact interior of the boiler casing without kinking, which could lead to blockages and boiler lockout.

Precision Fit: Features factory-molded ends to ensure a watertight connection to the heat exchanger outlet and the condensate trap assembly.

Genuine Vaillant Part: Guarantees full compatibility with the manufacturer’s warranty and ensures the hose meets strict safety and environmental standards.

Direct Replacement: This is the authorized replacement hose for modern ecoTEC and ecoFIT ranges.

Boiler Compatibility
This condensate hose is used across Vaillant's most popular modern condensing boiler ranges. Common compatible models include:

ecoTEC Plus (Combi, System & OV): 412, 415, 418, 424, 428, 430, 438, 612, 615, 618, 624, 630, 637, 824, 831, 837, 937.

ecoTEC Pro: 24, 28, 30.

ecoFIT Pure: 412, 415, 418, 425, 430, 435, 612, 615, 618, 625, 630, 825, 830, 835.

Technical Tip: If your boiler is displaying fault code F.29 or F.28 during cold weather, or if you notice water pooling inside the boiler casing, the condensate system may be blocked or leaking. Over time, debris from the heat exchanger can settle in this hose, preventing the free flow of water and causing the boiler to shut down.

Maintenance and Installation Advice
During an annual service, a Gas Safe engineer should inspect the condensate hose for signs of degradation, brittleness, or internal blockages. When replacing the hose, ensure the connections are secured with the correct clips and that there is a continuous fall toward the trap to prevent airlocks.

Essential Companion Products
To ensure a fully functional condensate disposal system, the following genuine Vaillant parts are often inspected or replaced alongside the hose:

Internal Sealing: Vaillant Lip Seal DN 60 - 981233

System Air Removal: Vaillant Automatic Air Vent - 0010033857
