The Gen1 from Aqua-Hot is a direct replacement for the Truma Combi.

It's multi-purpose appliance designed to save space and weight in a vehicle while still providing the highest level of climate comfort as well as 2.64 G of hot water.

The Aqua-Hot Gen1 can heat water independently of the furnace, keeping owners comfortable year-round and ensuring they’re always ready for a luxurious hot shower from anywhere on the road. Warm air flows into the coach’s interior through 4 air outlets where it is distributed evenly and efficiently for a consistently comfortable internal temperature.

The Aqua-Hot Gen1 is rated for high altitude operation up to 15,000 feet above sea level – compared to competitive models that are only rated up to 4,000 feet.

Gen1 uses RV-C Open-Source intelligence for user-friendly control and easy integration into your application.
