Water Heaters for Boats – Comfort Onboard


A water heater is an essential element for comfort and functionality onboard. Whether for dishwashing, showering, or general use, a marine water heater ensures a reliable supply of hot water and enhances the quality of life on sailboats, motorboats, and yachts.

Materials and High-Quality Construction


Our marine boilers are made from durable materials such as stainless steel (AISI 316), which is highly resistant to corrosion and acids. A high-quality polyurethane foam insulation minimizes heat loss, while plastic casings and stainless steel components ensure a long-lasting construction. These materials guarantee safe and efficient use in a maritime environment.

Different Types of Water Heaters


Compact Water Heaters


These space-saving models offer capacities between 15 and 80 liters and are ideal for smaller boats or tight installation spaces. Despite their compact size, they provide sufficient hot water for daily needs.

Horizontal and Vertical Water Heaters


These boilers offer flexibility in installation, depending on the available space onboard. They can be installed horizontally or vertically without losing efficiency.

Water Heaters with Various Heating Capacities


Our marine water heaters are available with heating elements ranging from 500W to 1200W, allowing optimal adjustment to your boat’s energy needs.

Technology for Efficiency and Safety


Modern boat water heaters use advanced technologies to maximize energy efficiency and safety. With electric heating elements (230V) and heat exchangers utilizing engine heat, water is efficiently heated. Additional features such as thermostatic controls and safety valves ensure easy operation and safe performance. Strong insulation keeps the water warm for an extended period, saving energy.

Applications for Every Need


Whether on a sailboat, motorboat, or yacht, a marine water heater is the perfect solution for having hot water onboard. Especially for long voyages or extended stays in the harbor, investing in a high-quality boiler is essential.

Top-Quality Brands for Reliable Performance


We offer products from renowned brands such as Sigmar Marine, Isotemp, and Quick, known for their high quality and reliability. With CE certification and tested safety standards, you can be assured of safe usage.
