Webasto is a world leader in marine heating, producing high-performance diesel air and liquid systems. Renowned for German engineering, Webasto systems provide efficient, quiet, and thermostatically controlled warmth specifically designed for the demanding marine environment.
Webasto Marine Heating Solutions
Webasto systems are categorised into two primary types: Air Heaters and Liquid Heaters (Boilers). Both utilise forced-draft diesel burners to provide reliable, on-board heat independent of the engine.
Expert Installation and Safety
Our OFTEC-trained engineers specialise in Webasto diesel heater installations, ensuring all connections meet Boat Safety Scheme (BSS) standards. Professional installation is vital to ensure carbon monoxide safety and optimal performance. We are currently offering free installation for our diesel heater narrowboat kits throughout the Winter 2025/2026 season.
Webasto Diesel Air Heaters
Air heaters provide rapid cabin warmth by drawing in cool air, passing it through a high-efficiency heat exchanger, and distributing it via ducts and blower boxes.
Air Top Evo 40 / 55: High-performance units for larger yachts with intelligent blower control to reduce noise and power consumption.
Air Top 2000 STC: The compact “all-rounder,” perfect for smaller boats and narrowboats.
Webasto Air Top 2000 STC: The most compact 2kW diesel air heater. Known for its quiet operation and ultra-low fuel consumption, making it the perfect choice for small to medium sailing yachts and cruisers.
Webasto Air Top Evo 40: A high-performance 4kW air heater featuring an intelligent blower control system. Ideal for larger interior volumes and multi-outlet heating configurations.
Webasto Air Top Evo 55: The most powerful air heater in the Evo range, delivering 5.5kW. Designed for extreme conditions and large vessels requiring rapid heating and high airflow.
Webasto Diesel Liquid Heaters (Boilers)
Liquid heaters (or “wet” systems) heat a water/glycol mixture circulated through radiators and SureCal calorifiers for domestic hot water.
Thermo Pro 90: A heavy-duty unit designed for larger yachts and commercial vessels requiring high heat loads.
Thermo Top Evo: A compact heater ideal for most leisure craft and domestic hot water needs.
Webasto Thermo Top Evo: A versatile 5kW diesel water heater. It provides consistent domestic hot water and powers radiator circuits, ensuring a “home-like” central heating feel on board.
Webasto Thermo Pro 90: A heavy-duty 9.1kW water heater. Features an Arctic Start function and stepless heating power control for large yachts and commercial vessels.
Webasto Controllers and Thermostats
Webasto offers a range of controllers and thermostats designed to enhance the user experience and optimize the performance of their heating systems. These advanced devices allow boat owners to easily manage their heating systems with precise temperature settings and intuitive interfaces.
Webasto MultiControl: A digital user interface with a programmable 7-day timer. Features a simple turn-and-push dial for easy temperature and mode adjustment.
Webasto Room Thermostat: A classic, easy-to-use analogue temperature controller. Provides reliable, straightforward management of your Webasto air or water system.
Frost Protection Thermostat: An essential safety component that automatically triggers the heating system when temperatures drop near freezing to protect your boat’s plumbing.
ThermoConnect TCON 2: An advanced LTE-based remote control system. Allows you to switch on, program, and monitor your heater from anywhere via a smartphone app or web browser.
