30mm marine exhaust system complete with silencer and insulation, designed for safe and efficient exhaust routing in boat heater installations. This complete exhaust kit (marine exhaust system / boat heater exhaust) provides everything needed for proper diesel heater exhaust setup, including noise reduction and heat protection for marine environments.
Marine Exhaust System 30mm (1.25" / 1-1/4") with Silencer & Insulation
This complete 30mm exhaust system (approximately 1.25 inch / 1-1/4") is designed for marine use with Eberspacher (Espar), Webasto, and similar diesel heaters used in boats. It includes an integrated silencer to reduce exhaust noise and insulation to improve safety by minimizing heat transfer within confined boat spaces.
Unlike standard exhaust pipes, this is a complete pre-configured marine exhaust solution, ideal for boat heater installations where safety, noise reduction, and correct exhaust routing are essential.
Most diesel heaters up to 19,000 BTU use a 24mm (approximately 1 inch) exhaust outlet, while larger systems typically use 30mm (1.25 inch / 1-1/4").
What You Need for Installation
If your heater has a 24mm exhaust outlet (approximately 1 inch – common on heaters up to 19,000 BTU, including models such as Eberspacher / Espar D2, D2L, D4, D4L, D4R, D5):
- 24mm to 30mm exhaust adapter
- Water drain coil for 24mm adapter
- This 30mm marine exhaust system (this product)
- 30mm through hull exhaust fitting
If your heater has a 30mm exhaust outlet (approximately 1.25 inch / 1-1/4"):
- 30mm to 30mm adapter (for water drain connection)
- Water drain coil
- This 30mm marine exhaust system (this product)
- 30mm through hull exhaust fitting
Using the correct combination of marine exhaust components helps ensure safe exhaust discharge, proper fitment, and long-term reliability of your diesel heater exhaust system onboard.
