BTU/h describes heat input; gallons describe stored volume. They measure different things. For a tankless unit, confirm usable flow at the temperature rise you need.
Record what is behind the exterior door. Bring these details to the model manual, the CAMPLUX team and your RV service professional.
W: width · H: height · D: usable depth. Illustration is not to scale.
Measure width, height and usable depth separately. Record the old model, available fuel and electrical supplies, door coverage and service clearances. Confirm the exact installation with the current model manual.
Ask about your setup
A shower, the dishes, a quieter evening in your RV. Start with the system that suits your routine, then make sure the available fuel, power and installation space support it.
Check each model’s operating conditions and winterization instructions. Freeze protection, where fitted, is not a substitute for preparing the RV and its plumbing for storage or loss of supply.
A product shortlist is the beginning. Use the exact model documents to check the complete installation and your seasonal use plans.
Record the old heater’s make, model and the exact replacement SKU you are considering.
Separate rough-opening width and height from usable depth and exterior door coverage.
Match propane, control power and electric-heating requirements to the exact model.
Check vent position, connections, access, seasonal use and the current manual with your installer.
Match the SKU and manual revision to the heater you are ordering.
Find model documentsReview current coverage, handling and delivery terms.
Read shipping termsCheck return eligibility and conditions before ordering.
Read return conditionsFor an outdoor wash station beside the RV, explore portable water heaters. They serve a different purpose from an installed RV replacement heater and must be used only in their approved locations.
A tankless unit heats water as it flows, so usable output depends on the required flow, inlet temperature and available fuel. The Ultra RG600 models store six gallons and offer propane, electric or combined heating. Choose around your camping routine, draw pattern and available supply, then confirm the specific installation requirements.
Some CAMPLUX product pages describe retrofit applications, but a brand name or old tank capacity does not establish a fit. Compare the exact existing model, the rough opening, available depth, exterior door coverage, vent location and service connections against the current manual for the new SKU. Have an RV service professional confirm the match.
No. The door covers the outside of the opening, while the heater body and its required installation space sit behind it. Measure opening width, height and available depth separately. Check the manual for mounting and service clearances as well as door coverage; a door measurement alone cannot confirm compatibility.
The linked RS264/RS264B manual specifies 12 V DC electrical input with propane as the fuel. The RG600 product descriptions specify 12 V DC ignition power and 120 V AC for electric heating. Check the exact manual for every model, including the Classic series. Fuel type does not tell you all of a heater’s electrical requirements.
A tankless heater must raise incoming water to the outlet temperature you need. Colder inlet water requires a larger rise, which changes the useful hot-water flow at a given heat input. Compare performance at the relevant temperature rise rather than treating a maximum GPM figure as the flow available in every campsite or season.
No. The RS264/RS264B manual describes freeze protection that depends on the required power and gas supply, and it also gives separate winterization instructions. For travel, storage, power loss or freezing conditions, follow the instructions for your exact model. Do not assume that a built-in feature protects every pipe or replaces winterization.
Portable outdoor shower heaters and built-in RV water heaters serve different applications. An outdoor-only portable heater must not be treated as an appliance for the RV interior or an enclosed compartment. Use the dedicated portable collection for campsite shower options, and verify the approved location and installation instructions for the product you choose.
Use the exact SKU and package listing, not the series name alone. The current built-in models are listed separately in black and white. Confirm the included door, its coverage, the heater body and the controls on that product page before ordering; a color choice does not change the need to confirm installation fit.
Share your existing heater’s make and model, opening width and height, available depth, a photo of the existing exterior opening and connections, and the CAMPLUX SKU you are considering. Include the fuel and electrical supplies you can confirm. The fit checklist on this page helps organize those details; it does not approve an installation.
Have your existing model, opening measurements and the CAMPLUX SKU ready. We can help you find the right product documents and the next questions for your RV installer.
