ATI BL22 Marine Water Heater 22L 230V

Description

The ATI BL22 Marine Water Heater 22L 230V is a compact marine hot water system engineered for yachts, sailboats and motorboats where reliability and efficient use of onboard space are essential. Manufactured in Italy by ATI Mariani Thermo Group, this model combines proven engineering, durable construction and dependable hot water production for everyday cruising and extended voyages.

With a 22-litre capacity, a built-in engine heat exchanger and a 230V electric heating element, the BL22 provides hot water whether the vessel is underway or connected to shore power. Its corrosion-resistant design, high-quality components and efficient heat transfer make it an excellent choice for both new boat installations and replacement projects.

Dual Heating System

The ATI BL22 utilizes two independent heating methods:

• Heat exchange from the engine cooling circuit
• Electric heating element powered by 230V shore power

This dual heating concept allows water heating while the vessel is underway or when connected to shore power in the marina. The internal heat exchanger transfers engine heat efficiently through the center of the tank for uniform water heating.

Premium Marine Construction

The BL22 is designed for long-term reliability in marine applications and incorporates premium materials throughout its construction:

• Enamelled steel storage tank
• Enamelled steel heat exchanger
• Pre-painted aluminum external casing
• Closed-cell polyurethane foam insulation
• AISI 304 stainless steel mounting brackets
• Magnesium anode for galvanic corrosion protection

The magnesium anode protects the tank against corrosion and extends service life in harsh marine environments.

Efficient Thermal Insulation

The high-density closed-cell polyurethane insulation minimizes heat loss and improves energy efficiency. According to the manufacturer, heat loss is limited to approximately 1°C per hour over a 24-hour period.

Electric Heating Element

The ATI BL22 230V series is available with three electric heating power options:

Model	Power	Current	Heating Time*
BL2212	1250 W	5.4 A	37 min

*Heating from 15°C to 45°C (ΔT = 30°C).

The heating element is manufactured from corrosion-resistant INCOLOY alloy, ensuring durability and long operational life in marine environments.

Adjustable Thermostat & Safety

The integrated thermostat provides both temperature regulation and safety protection:

• Adjustable temperature range: 13°C to 65°C
• Safety cut-off temperature: 83°C
• Manual reset function
• Maximum current: 16 A

These features ensure safe and reliable operation onboard.
