Marine heater installation kit for safe onboard heating
Install your diesel air heater in a marine environment with the right exhaust, fuel, mounting, and combustion air components for safer onboard heating. This marine installation kit is suitable for Eberspacher Airtronic D2, D2L, D4, D4R and D4L heaters, and can also be used with Webasto EVO 40/55 heaters when installed correctly.
Benefits & Use Cases
This marine upgrade kit is designed for boat owners who already have a universal heater installation kit and need the correct marine components for a cabin, berth, or small vessel heating setup. It helps support a cleaner, more durable installation with marine-grade exhaust, fuel, drain, and mounting parts.
The insulated marine exhaust silencer, 30 mm thru-hull fitting, water drain, and stainless steel mounting bracket make this kit a strong choice for replacing basic non-marine installation parts in onboard diesel heater systems.
