Will the RVPart Pro 42,000 BTU RV Tankless Water Heater fit in a 15×15 inch space?

You must confirm your mounting area provides extra clearance for the mounting brackets and exhaust venting before ordering. Start by measuring your available wall space to ensure the 15-inch width does not block adjacent components.

RVPart Pro 42,000 BTU water heater requires more than 15×15 inches

We selected this unit for our comparison because it offers a 150 PSI pressure reducing valve and a 5000+ ft altitude rating. Because RV tankless water heater installations often require additional space for the exhaust venting and water inlet/outlet plumbing, a 15×15 inch area is the minimum footprint for the unit itself. If your mounting surface is exactly 15×15 inches, the external plumbing and the 150 PSI pressure reducing valve—which regulates the flow of water into the system—may exceed the available space. Choosing a unit that does not fit leads to a costly return or a forced relocation of other interior components.
