Quick Stainless Steel Nautic Boiler B3 1200W Round with Heat Exchanger 15L & 20L

The Quick Nautic Boiler B3 series delivers superior hot water performance for marine applications, combining efficient heating with unmatched corrosion resistance. Available in 15L and 20L capacities, this marine water heater uses a powerful 1200W heating element and an AISI 316L stainless steel heat exchanger that offers exceptional heat transfer efficiency — significantly higher than many comparable models.

The tank is crafted from 1.5 mm AISI 316 stainless steel, welded using Argon shielding gas for enhanced protection against saltwater corrosion. Its composite outer casing and high-density polyurethane foam insulation ensure excellent thermal retention, keeping water hot for longer. The Incoloy® heating element provides consistent performance, while the built-in adjustable safety thermostat and relief/non-return valve add layers of safety and reliability.

Ideal for boats and yachts, the Nautic Boiler B3 is designed for long-term durability and easy installation, with stainless steel mounting brackets included as standard.
