Autoterm Baltica System - Diesel / 12V / 230V

AUTOTERM Baltica is a premium All-in-One Heating System designed to combine domestic hot water, coolant heating, and interior air heating support in one integrated system.

Built for vehicles, boats, campers, and specialized installations, Baltica provides a compact and efficient solution for users who need reliable comfort, hot water availability, and flexible heating performance in one system.

The system is based on a 13 L expansion tank with an integrated heat exchanger, allowing hot water to be available within approximately 6-10 minutes after activation.

For additional heating performance, Baltica is equipped with two 800 W electric heating elements for direct grid connection. These elements include a preset 90°C thermostat and a safety cutoff between 91–95°C.

Designed for:

• Domestic hot water supply
• Hydronic heating systems with radiators
• Fan coil heating systems
• Secondary compartment heating when used with Baltica Control
• Marine, camper, vehicle, and specialized installations

Key benefits:

• All-in-one solution for water, air, and coolant heating
• 13 L integrated expansion tank with internal heat exchanger
• Hot water availability within approximately 6-10 minutes
• Two integrated 800 W electric heating elements for grid support
• Can support interior heating through radiators or fan coil units
• Suitable for standalone use or integration into custom heating systems

Domestic hot water performance:

Baltica System uses an internal heat exchanger to provide instant domestic hot water. To ensure a steady hot water supply, a flow regulator must be installed.

The recommended water flow rate is 3.5 L/min, helping maintain stable water temperature and reliable performance during use.

Air and compartment heating:

In addition to domestic water heating, Baltica can support interior heating when connected to compatible heating accessories such as radiators or fan coil units.

When used with Baltica Control, the system can manage heating demand automatically and operate fans or third-party heating devices through relay-based heat-on-demand operation.

Grid heating support:

The integrated grid heating elements are independent heating devices designed to maintain coolant temperature when connected to shore power or external grid supply.

The system can operate together with the Baltica Flow 5 for additional heating support or in GRID-only mode, where stored heat can be used for domestic water and space heating without running the heater.

When GRID mode is active, Baltica Flow 5 heating settings are locked. To enable Baltica Flow 5 heating, GRID mode must first be switched off.

Control options:

• Push Control: basic control, automatic pump start/stop, and automatic fan stop at target temperature

• Baltica Control: automatic pump control, automatic heating fan management, target-temperature fan stop, and secondary compartment heating function

Installation notes:

• The Baltica System expansion tank must be installed vertically
• The tank must be securely fixed using original mounting brackets
• Alternative mounting positions are not permitted
• Minimum clearance of 5 cm must be maintained on all sides
• The system must be installed with adequate ventilation
• The coolant piping between the heater and tank must not exceed 3 meters
• The heater must be installed within +/- 50 cm from the tank centerline if mounted separately
• An overflow pipe must be connected to prevent coolant or steam discharge into the compartment

Coolant requirements:

We advise using AUTOTERM Aluminium EKO Coolant - a specialized propylene glycol coolant designed for safe and reliable operation of the Baltica system. Alternative non-corrosive propylene glycol may be used, as long as it has the same specification as Aluminium EKO Coolant.

Do not use water as coolant. For non-domestic applications, G13 antifreeze may be used.

Technical specifications:

• Tank volume: 13 L

• Maximum operating pressure: 1.1 bar

• Recommended water flow rate: 3.5 L/min

• Coolant: Propylene glycol only for domestic water applications

Maintenance recommendations & usage:

Kit includes: 13l Baltica Expansion Tank; Coolant Overflow Pipe; Electric Cable; Installation Manual.

• Regularly inspect the system for leaks and ensure the safety valve operates correctly

• Inspect electrical terminals every 6 months

• Check coolant once a year

• Flush the system every 2 years

Important: Installation and service must be carried out according to the official AUTOTERM Baltica manual and by qualified personnel. Improper installation, incorrect coolant use, or unauthorized modifications may affect system performance, safety, and warranty.
