Tiffin Motorhomes Inc. has added Aqua-Hot Heating Systems’ new 250D hydronic heating solution to its list of upgraded features on the 2019 Allegro RED Class A luxury motorhome.

According to a press release, the system provides 40,000 Btu/hr of evenly distributed warmth without the dry, blowing air associated with traditional systems, plus continuous hot water for a residential-style experience.

The Aqua-Hot 250D uses diesel fuel and is operated by 12VDC for off-grid applications. When plugged into shore power, it can run on a 110VAC electric element. Although compact in size, it easily heats the close to 2,200-cubic foot interior. The system weighs 84 pounds empty and 113 pounds full.

“We chose the Aqua-Hot solution because it offers continuous hot water and consistent heating throughout, without the temperature variation you get with forced air,” said Andy Baer, Tiffin Motorhomes. “It also allows the coach to be propane-free.”

Tiffin’s Allegro RED features four slideouts and is powered by a Freightliner rear-engine diesel chassis and an after-cooled Cummins ISB 6.7-liter engine.
