Quick Nautic Boiler BK – Premium Marine Water Heater

The Quick Nautic Boiler BK is engineered for superior performance and long-lasting reliability, making it a trusted choice for marine hot water systems. Designed and built in Italy, it combines advanced materials with exceptional craftsmanship to ensure consistent hot water and excellent durability in demanding marine environments.

At the heart of the Nautic Boiler BK is a high-efficiency AISI 316 stainless steel heat exchanger, offering significantly greater heat transfer capacity than comparable models on the market. The inner tank, also constructed from AISI 316 stainless steel, is argon gas welded for maximum strength and resistance against corrosion, ensuring long service life even in harsh seawater conditions.

The unit’s electrical heating element is made from Incoloy®, a highly durable alloy designed to withstand high temperatures and continuous use. Surrounding the tank is a thick layer of polyurethane foam insulation, injected between the cover and the tank to provide outstanding heat retention and energy efficiency.

Encased in a robust PVC and composite shell, the Nautic Boiler BK combines functionality with a clean, modern design. Additional features include:

  • A large-surface heat exchanger for rapid water heating
  • Dual heating capability, producing hot water via the electric element and heat exchanger#
  • An adjustable safety bi-thermostat for precise temperature control
  • A relief/non-return valve that allows safe discharge when the heater is not in use
  • An intuitive temperature control panel for easy operation
  • Adjustable levelling feet for simple installation and stability

Built from premium materials and designed for the marine environment, the Quick Nautic Boiler BK ensures reliable performance, superior heat retention, and consistent comfort on board.
