The WATERHEATER by ITR is a quiet and efficient diesel fired continuous output potable water heater. The diesel burner provides 35,000 TRUE OUTPUT™ BTU for continuous hot water output and has an internal mixing valve to set your preferred hot water temperature.

The WATERHEATER includes a 1500W electric immersion element providing an extra 5000 BTU for supplemental heat when on shore power and a 5.5 US gallon (20 liter) coolant tank capacity to make best use of this electric element to store its heat.

The WATERHEATER features a stainless steel 300 PSI welded tank, stainless steel outer case and high temperature stainless burner.

The WATERHEATER uses ITR’s patented “no-smell, no-smoke” burner platform. This proven technology is quiet, and clean-burning, and improves safety and efficiency, while also lengthening system maintenance cycles.
