Application

The Pundmann Therm Boiler TOWER 6L is the ideal hot water heater wherever space is limited and reliability is essential. In a motorhome or trailer, it ensures you can comfortably shower or wash dishes after a long day of travel—at a campground using shore power, or out in the wilderness using the vehicle’s 12V battery. Van life enthusiasts appreciate the slim TOWER design, which integrates perfectly into tight service compartments or under-cabinet spaces. On boats and yachts, it ensures a reliable hot water supply in port via 230V or at sea via 12V. It also performs exceptionally well in food trucks, mobile service vehicles, and specialty vehicles, where clean hot water is needed daily.
