One box replaces three systems. The Autoterm Baltica is a complete hydronic heating solution that handles cabin warmth, domestic hot water, and engine pre-heating from a single compact unit — no separate boiler, no extra plumbing runs, no compromises on van space.
At the heart of the kit is a 13-litre stainless steel expansion tank with a built-in plate heat exchanger. Connect it to the specialist Baltica Flow 5D diesel heater and you have shower-ready hot water in 6 to 10 minutes, plus heat distributed through whatever setup you've built — fan coil blower boxes, radiators, or underfloor heating loops. The system also supports a 1,600W electric mode (two 800W elements) so when you're on a campsite hook-up or running a large inverter, you can heat the water and van without touching your diesel at all.
The included Baltica Control panel handles everything automatically — coolant pump management, temperature regulation, and switching between diesel and grid modes. You set the target temperature; it does the rest.
What's in the box:
- Autoterm Flow 5D Baltica-version diesel heater (5kW)
- 13L Baltica expansion tank with integrated heat exchanger and dual 800W electric elements
- Baltica Control panel
- Wiring harness and cables
- Coolant overflow pipe and installation manual
Important: This system requires the specialist Baltica version of the Flow 5D heater — standard Autoterm Flow 5 units are not compatible due to firmware differences.
