Aqua-Hot 125G Hydronic Heater (Gasoline, 17,000 BTU)

Currently out of stock. Estimated shipping begins late May 2025.  Need quiet, powerful heating for your gasoline camper van/RV? The Aqua-Hot 125G Hydronic Heater (Gasoline, 17,000 BTU) is a compact, fuel-efficient, gasoline-powered hydronic heater that will keep your rig toasty warm on even the coldest nights. And it's not just going to be warm right next to the heater: 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. If you want a complete heated floor/continuous hot water heating solution, the Aqua-Hot 125G pairs perfectly with the Columbia Heated Floor System. Add the In-Floor Heating Kit, and the suitable version of the Columbia system. Always at high altitudes? The 125G automatically adjusts fuel-to-oxygen mix, enabling it to heat efficiently at up to 16,000 ft. without the maintenance issues found in other units. If you're off-grid, the 125G can operate entirely from the gasoline from your main fuel tank. If you have access to shore power, you can optionally use the 125G's electric heating element for additional heater capacity. This complete Aqua-Hot 125G Hydronic Heater kit contains every component you need for a camper van/motorhome installation, including the all-in-one enclosure, gasoline burner, exhaust and intake tubing, and two heat exchangers. Additional heat exchangers are sold separately.  The Aqua-Hot 125G uses a propylene glycol-based antifreeze and water heating fluid, and the heater must be checked monthly to make sure there is adequate fluid. Annually, the fuel nozzle and fuel filter must be replaced. Also, the heater must be winterized if not in use, with all fresh water drained and antifreeze solution pumped throughout the system.
