The 125 Modular is a complete hydronic heating system providing luxurious comfort and continuous hot water with individual components installed neatly where interior space allows.

Aqua-Hot heating systems have been bringing comfort to RVs for over 35 years. The 125 Series hydronic heating system has a compact footprint that brings comfort and reliability to Class B (Campervan) owners.

By tapping into the vehicle fuel system, the 125 doesn’t need additional fuel. By automatically adjusting the fuel-to-oxygen mix, the 125 efficiently performs at up to 16,000 ft. without the maintenance issues found in other units.

With a closed loop thermal fluid system, interior heat can be brought directly to where it is needed—the galley, the sleeping area and the seating areas. In addition, the LCD controller can adjust the heat output from each zone independently.

The 125 delivers continuous hot water at .8 gpm for your convenience—at a consistent temperature of 110-120°F.
