The OASIS NE is an all-in-one hydronic heating system designed as an improvement and replacement for the Aqua-Hot 450D and similar heaters. See Brochure

The OASIS NE produces 50,000 True Output BTU, and will outperform any heater in its size category. The OASIS NE burner is supplemented by two 1500 watt AC electric elements that provide an additional 10,000 BTU to the system for use under shore power. The NE can be ordered as a front and left access OR front and right access model for proper installation and access.

The OASIS NE will provide on-demand, continuous 120°F potable water at 1.5 GPM flow rates with no interruption to internal coach heating. The OASIS NE also features a large 7.5 gallon stainless steel coolant tank for increased heat storage, significantly reducing burner cycling times and reducing fuel consumption.

Additional standard features include dual-loop circulation for space heating up to five separate thermostatically controlled zones, “never-run-dry” pump protection, engine waste heat management, plug-and-play wiring for easy electrical hook-up, and comprehensive on-board diagnostics. An optional feature is an engine pre-heat system to prevent cold engine starts. Another optional feature is the ITRTouch™ remote control interface, which simplifies control, operation and diagnosis of the OASIS NE system.

The OASIS NE is UL/CSA certified. Like all OASIS systems, it is built on a patented low-pressure burner platform that is unique in its safe, quiet, “no-smoke, no-smell,” technology, which improves efficiency and lowers system maintenance cycles.
