Product Details

The Contoure AA-4200BTU is a 42,000 BTU on-demand tankless propane water heater purpose-built for RV, camper, and motorhome applications. Designed as a direct retrofit for standard RV water heater openings, it delivers continuous hot water on demand—eliminating the wait times and limited supply associated with traditional tank-style RV water heaters.

Key Features:

  • 42,000 BTU propane burner for powerful, rapid water heating on demand
  • Tankless on-demand design provides endless hot water flow without a storage tank
  • Includes a white access door for clean, finished installation into standard RV exterior openings
  • Designed for easy retrofit installation into most RVs, campers, and motorhomes
  • Propane (LP) fuel compatible — ideal for off-grid and extended travel use
  • Compact, space-saving design frees up valuable interior RV storage compared to tank units

The Contoure AA-4200BTU is an excellent solution for RV owners looking to upgrade to a modern tankless hot water system with straightforward installation and reliable performance on the road.

I searched online for my product, found it and the best price at thmotorsports.com, ordered it, and received it as promised, in perfect condition as advertised. I'm a satisfied customer. Guess they have a sister company: autoplicity.com. I'm shoppin' them too.
