Aqua-Hot Heating Systems, a supplier RV hydronic heating solutions, has added the 250D to its 200 series lineup. 

According to a press release, the 250D is ideal for smaller RVs that already have diesel onboard. Aqua-Hot will debut the new product in Booth No. 2339 at RVX: The RV Experience, slated for March 12–14 in Salt Lake City, Utah. The hydronic heater is already available on Tiffin Motorhome Inc.’s Allegro RED as an option.

The Aqua-Hot 250D delivers 40,000 Btu/hr of warmth without cold spots or dry, blowing air. Low-voltage fans ensure quiet operation. Similar to luxury residential and high-end motorhome systems, it is set by a thermostat and uses high-efficient heat exchangers and/or in-floor radiant heating.

The Aqua-Hot 250D also provides continuous hot water, eliminating the need for a separate water heater. Delivering a 1.5 gpm flow at 110º–120º F, it’s ideal for showering, laundry and other uses.

The Aqua-Hot 250D is fueled by diesel and operated by 12VDC for off-grid applications. The system also utilizes a 110VAC electric element when the coach is plugged into shore power. Compact and lightweight, it’s the 250D weighs 84 pounds empty and 113 pounds full.

The all-in-one design is straightforward to install. Heating, water and fuel ports are located on top for easy connection. An integrated mounting tray facilitates air intake and exhaust.
