Why Dimensions Matter For Rv Water Heaters
Space is precious in an RV. Every inch counts—especially in kitchens, bathrooms, or storage compartments. If your water heater is too big, it won’t fit. If it’s too small, it may not supply enough hot water. The dimensions of the Apus RV tankless water heater affect not just installation, but also efficiency, safety, and overall comfort. Tankless models are usually smaller than traditional tank heaters, but differences exist between brands and models.

Beyond physical fit, the size can impact airflow, maintenance access, and even the noise level. Some RVs have dedicated heater compartments, while others require creative placement. Knowing the exact measurements helps you avoid mistakes, wasted money, and installation headaches.

The Apus RV tankless water heater is designed with compactness and portability in mind. Here are the typical dimensions for the most popular Apus RV tankless models:

Key Dimension Details
- Height: This is the vertical measurement from bottom to top. It’s crucial for under-sink or wall-mount installations.
- Width: This is the side-to-side measurement, affecting how the heater fits in narrow spaces.
- Depth: This is the distance from front to back. Too much depth means the unit may protrude or not fit behind doors.
- Weight: A lighter model is easier to install, but heavier models often have more features or capacity.
Comparing Apus Tankless Water Heater Dimensions To Other Rv Models
How does Apus stack up against other popular brands? RV owners often compare dimensions to brands like Girard, Suburban, and Truma. Here’s a comparison to help you see the difference:
| Brand | Height (inches) | Width (inches) | Depth (inches) | Weight (lbs) |
|---|---|---|---|---|
| Apus Standard | 12.8 | 12.6 | 7.1 | 18 |
| Girard GSWH-2 | 12.5 | 15.5 | 6.5 | 21 |
| Suburban IW60 | 12.7 | 12.7 | 7.3 | 19 |
| Truma AquaGo | 12.6 | 15.7 | 6.4 | 17 |
As you can see, the Apus Standard is similar in height and depth to other models but a bit narrower than Girard and Truma. This can be a major advantage if your compartment is tight or oddly shaped.
Insights For Buyers
- Smaller width means easier replacement in older RVs with limited space.
- Weight varies, so check your wall or mounting surface strength.
Many beginners don’t realize that even a half-inch difference can mean the heater won’t fit—or it will require cutting or modifying your RV compartment.

Clearance Requirements
The Apus RV tankless water heater needs minimum clearance around it for proper ventilation and safety. Most models require:
- At least 2 inches of space on all sides
- 6 inches of clearance at the top for venting
- Unobstructed access at the front for maintenance
If you squeeze the heater into a tight compartment, it may overheat or become hard to service.
Mounting And Support
Because the heater weighs between 15 and 22 lbs, you need a strong mounting surface. Thin walls or cabinets may need reinforcement. Wall-mount brackets are often included, but check their quality before installing.
Plumbing And Electrical
While the heater is compact, plumbing hoses and electrical wires add bulk. Make sure your compartment can accommodate these extras. Some users forget to measure space for pipes and end up with a heater that fits—but the hoses don’t.
Venting
Tankless heaters need venting to the outside. The depth measurement is important because you must line up the vent with the RV wall. If the heater is too deep, the vent may not sit flush.
Practical Tips For Measuring And Installing
- Measure your compartment carefully—width, height, and depth. Use a tape measure and check for irregularities.
- Account for clearance. Add at least 2 inches to each dimension for safe installation.
- Check door swing. Make sure the compartment door closes without hitting the heater.
- Look for obstructions. Pipes, wires, or shelves can affect fit.
- Dry fit the heater before final installation—place it in the compartment to test fit.
Common Mistakes
- Forgetting to measure clearance for pipes and wires
- Ignoring the venting requirements
- Assuming all tankless heaters are the same size
- Not reinforcing mounting surfaces
New RV owners often think a compact heater will fit anywhere, but overlooking these points leads to frustration and costly fixes.
Benefits Of Apus Rv Tankless Water Heater’s Compact Size
The compact dimensions of the Apus RV tankless water heater offer several advantages:
- Easy installation in tight spaces
- More storage space in your RV
- Less weight means easier handling and transport
- Flexible placement—can fit under sinks, in small cabinets, or wall-mount locations
Smaller size also means less visual clutter and more room for other appliances or gear. However, it’s important to match the heater’s capacity to your hot water needs.
Hidden Benefit: Quiet Operation
A compact heater often runs quieter, especially in small spaces. Fewer moving parts and less vibration mean you can enjoy hot water without annoying noise.
Capacity Vs. Dimensions: Don’t Sacrifice Performance
Many buyers worry that smaller heaters provide less hot water. With the Apus RV tankless water heater, capacity is not compromised. The Standard model delivers up to 6 gallons per minute—enough for a shower and kitchen use at the same time.
But if you have a larger RV or more people, consider the Apus Pro, which offers up to 8 gallons per minute. Always check both dimensions and capacity before buying.
| Model | Dimensions (HxWxD) | Max Flow Rate (GPM) | Recommended RV Size |
|---|---|---|---|
| Apus Standard | 12.8 x 12.6 x 7.1 | 6 | Small/Medium |
| Apus Mini | 11.0 x 10.2 x 6.5 | 4 | Small |
| Apus Pro | 14.3 x 13.1 x 7.8 | 8 | Large |
Real-world Examples: How Dimensions Affect Rv Owners
Let’s look at some practical situations:
- Small camper: The Apus Mini fits under the kitchen sink, freeing up bathroom space.
- Class A RV: The Apus Pro fits in the main utility compartment, handling multiple showers.
- Older RVs: The Apus Standard replaces bulky tank heaters, reducing weight and improving efficiency.
RV owners often report easier installation and fewer problems with Apus tankless heaters due to their compact design. Some even use the extra space for storing cleaning supplies or tools.
How To Check If The Apus Rv Tankless Water Heater Will Fit
Before buying, follow these steps:
- Locate the compartment where you plan to install the heater.
- Measure height, width, and depth—include clearance for pipes and wires.
- Compare your measurements to the Apus model dimensions.
- Check for venting access—make sure the vent can exit the RV wall.
- Consider weight—ensure your mounting surface is strong enough.
If your compartment is smaller than the heater’s dimensions plus required clearance, look for the Mini model or consider modifying your space.
Installation Process Overview
Installing the Apus RV tankless water heater is straightforward if you plan ahead. Here’s a basic guide:
- Remove the old heater—disconnect water, gas/electric lines, and vent.
- Prepare the compartment—reinforce walls if needed, clear obstructions.
- Dry fit the new heater—check alignment and space.
- Mount the heater—use supplied brackets, secure firmly.
- Connect plumbing—attach water lines, check for leaks.
- Connect power/gas—follow manufacturer instructions.
- Install vent—ensure proper alignment and seal.
- Test operation—run water, check temperature, listen for noise.
Always follow the manufacturer’s instructions. If unsure, hire a professional RV technician.
Maintenance Access: Why Dimensions Matter
A smaller heater is easier to maintain. The Apus RV tankless water heater’s compact size means you can reach filters, valves, and wires without squeezing into tight spots. If you need to replace parts or clean the unit, having enough space for your hands and tools makes a big difference.
Many users overlook maintenance access when choosing a heater. If the compartment is too tight, even changing a filter can be difficult.
Apus Rv Tankless Water Heater Dimension Insights For Beginners
If you’re new to RV upgrades, here are two important insights:
- Double-check vent alignment. The depth measurement must match the distance from the heater to the RV wall—otherwise, the vent won’t fit or seal properly.
- Think about future upgrades. If you plan to add insulation or extra plumbing, leave extra space. Don’t choose a heater that barely fits.
It’s easy to focus on the heater’s size and forget about cables, pipes, and vents. Plan for future repairs or upgrades—extra space can save you trouble down the road.
