Will the RVPart Pro GT60 Tankless Water Heater fit in a 15×15 inch opening?

You must measure your mounting area to ensure you have the required clearance for the mounting bracket, which secures the unit to the wall, and the flue pipe, which directs exhaust away from the RV.

RVPart Pro GT60 dimensions and heating capacity for RV installations

The GT60 Tankless Water Heater provides a 60,000 BTU heating capacity, which allows it to run a shower for 10 minutes without a flame out even in demanding conditions. For RV owners, verifying the footprint is critical because these instant water heaters—devices that heat water on demand as it flows through a heat exchanger—often require additional space for the flue pipe and internal components. The unit includes a built-in 150 PSI pressure reducing valve and a 12V DC power supply for operation. While the 15″ x 15″ dimension covers the main body, the listing does not state the specific clearance zone required for maintenance access or the exact dimensions of the included mounting hardware.

Comparing the GT60 Tankless Water Heater to Other Options

The GT60 Tankless Water Heater serves buyers who prioritize high heat output and a compact footprint for standard RV installations. If you require a larger flow rate than the 3.9 Gallons per Minute provided here, or if your RV has a non-standard mounting area that cannot accommodate a 15×15 inch footprint, you may need to look at larger industrial-style units. This model is a strong choice for standard setups where space is at a premium but high-altitude performance is required.
