Pundmann Therm 4-in-1 AIR FLOW HEAT 10L – Glycol Engine + Air Heater + 12V+110V
The Pundmann Therm AIR FLOW HEAT 10L is Pundmann's most advanced and versatile boiler — a true 3-in-1 (or 4-in-1) hot water system for the most demanding overland builds and live-aboard setups. It connects to your vehicle's engine cooling circuit (heat while driving), your diesel/gasoline auxiliary heater (heat while parked), and provides two electric backup modes via 12V DC and 110V AC.
Heat Sources — All Four, One Unit
- Engine FLOW — heat from engine coolant while driving
- AIR Heat Exchanger — captures waste heat from diesel/gasoline parking heater
- 12V DC / 200W — from battery or solar
-
110V AC / 1000W — shore power or generator (1200 W Total Electric)
Key Features
- Three heat sources: air heat exchanger + 12V DC / 200W + 110V AC / 1000W
- Compatible with 2kW and 4kW auxiliary air heaters (Autoterm, Webasto, Espar)
- 10-liter food-grade stainless steel tank
- Engine coolant connections for drive-time heating
- 90mm hot air duct connection (60mm adapter available separately)
- 3.5 bar pressure relief valve — safe for pressurized water systems
- EPP soft-shell insulation for excellent heat retention
- Auto shut-off thermostat at 70–75°C
- Ideal capacity for 1–2 person van or overland builds
- Drain valve opening to blow out for winterization
- Mixing valve Included to avoid scolding temperatures
- DC/DC switch included to optionally turn on heating elements (Fast and Slow energy-efficient heating options)
Ideal For
Expedition vehicles, 4x4 overland trucks, large camper vans, and anyone who demands maximum hot water availability with zero compromise on self-sufficiency.
