The Baxi 5118378 Condensate Body Kit is a genuine replacement component designed to collect and channel acidic condensate produced during normal boiler operation into the condensate drainage system. In modern condensing boilers, water vapour in the flue gases cools and condenses; the condensate body ensures this liquid is directed safely away from sensitive internal parts and into the drain, preventing blockages, leaks or internal corrosion. A correctly functioning condensate body supports reliable operation and helps reduce the risk of pressure faults, interruption of heat output or boiler lockouts.

This condensate body kit is compatible with Baxi Duo Tec, Megaflo and Platinum Combi series boilers that reference part number 5118378 in their technical documentation. To ensure correct fitment, always verify the part number on your existing condensate assembly or consult your boiler’s service information before installation, as condensate system layouts and connection sizes vary between models.

Supplied ready for direct replacement, the 5118378 Condensate Body Kit connects to the boiler’s condensate outlet and drain pipework without modification when installed by a qualified engineer. Choosing this genuine Baxi component helps restore effective condensate drainage, supports continuous safe boiler operation and contributes to dependable heating and hot-water performance in compatible Combi systems.
