Pundmann Therm Boiler 6L 12V/110V + AIR Water Heater
The Pundmann Therm Boiler AIR 6L is the ultimate tri-source hot water heater for serious off-grid builds. It integrates a built-in air heat exchanger that harvests waste heat from your diesel parking heater (Autoterm 2D/4D, Webasto, or equivalent), combined with 12V DC and 110V AC electric elements for complete hot water flexibility in any situation.
You can standardize with 2 rods, which is very efficient, or you could opt to add an additional heating rod to zap water quickly.
Why AIR?
When your diesel heater is running to warm your van, the AIR model captures that waste heat and heats your water simultaneously — at zero extra fuel cost. This is the most energy-efficient hot water setup possible for a mobile build.
Key Features
- Three heat sources: air heat exchanger + 12V DC / 200W + 110V AC / 1000W
- Option for 3rd 1000W Element for 2200W total
- Compatible with 2kW and 4kW auxiliary air heaters (Autoterm, Webasto, Espar)
- 6-liter food-grade stainless steel tank
- 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)
Specifications
- Capacity: 6 Liters
- Air Duct Connection: 90mm diameter
- Voltage: 12V DC / 110V AC (US spec)
- Power: 200W (12V) / 1000W (110V)
- Max Pressure: 3.5 bar
