When it comes to rapid cabin warmth and efficient moisture control on a vessel, diesel air heaters are the industry standard for year-round cruising. These systems function by drawing air from the cabin or an external source, passing it through a high-efficiency heat exchanger, and distributing dry, heated air through a network of ducting. For boaters on the UK canal network or coastal waters, this provides a “set-and-forget” heating solution that can be controlled via thermostatic panels or mobile apps, ensuring a warm welcome before you even step on board.

Safety & Regulatory: OFTEC and CRT

Diesel air heater installations require precision, particularly regarding fuel delivery and exhaust routing. To maintain compliance with the Boat Safety Scheme (BSS) and Canal & River Trust (CRT) regulations, all exhaust systems must use marine-grade skin fittings to prevent carbon monoxide ingress.

We strongly recommend that all units are commissioned by an OFTEC registered technician. This ensures your installation meets the latest fire safety standards and protects your vessel’s insurance validity. Proper ventilation and fuel line integrity are paramount when installing systems from brands like Webasto and Eberspächer to ensure long-term reliability on the water.
