Finally! A furnace and water heater combination with high altitude performance up to 15,000 ft.

35 years of design expertise back the luxury RV comfort systems by Aqua-Hot now featuring the innovative Gen1.

You no longer need a separate heater and water heater in your van.

The Gen1 is a multi-purpose, single appliance designed to save space and weight in a vehicle while still providing the highest level of environmental comfort as well as 2.64 G of hot water.  With 13,500 BTU of heating capacity (20,000 for propane version). The Aqua-Hot Gen1 can heat water independently of the furnace, keeping camper van 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 5,200 feet.  Gen1 also uses RV-C Open-Source intelligence for user-friendly control and easy integration into the camper van’s multiplex system.

The Aqua-Hot Gen1 heater comes with every component you need for a camper van/RV heater installation, including the Gen1 heater, control panel, flexible ducting, and exhaust and intake tubing.

Replace a Truma Combi

This Aqua-Hot Gen 1 is also a perfect replacement for a Truma Combi at a great price. The form factor, venting, and location of all the ducting/connections allow for a simple, direct replacement with little hassle or retrofit required. Even the holes for mounting the unit are located in the same location as a Truma Combi.
