Apus RV Tankless Water Heater vs Furrion: Ultimate Comparison

When you’re traveling in your RV, comfort is everything. Hot water is not just a luxury—it’s a necessity for showers, washing dishes, and cleaning up after a long day on the road. The right tankless water heater can make a huge difference in your experience. Two of the most talked-about brands today are Apus and Furrion. Both offer modern tankless models designed for RVs, but which one is actually better for your needs? This guide will break down the differences, features, and real-world performance of each brand, so you can confidently choose the best option for your adventures.

Why Go Tankless In Your Rv?

Traditional RV water heaters use a storage tank. They keep water hot all the time, even when you’re not using it. This means wasted energy and, often, running out of hot water in the middle of a shower. Tankless water heaters heat water only when you need it, giving you endless hot water (within flow limits) and saving energy.

Here’s why more RV owners are switching to tankless systems:

• Continuous hot water: No more cold surprises during a shower.
• Energy efficiency: Heats only what you use.
• Space-saving: Smaller and lighter than tank models.
• Less maintenance: Fewer parts, less risk of rust or scale buildup.

But not all tankless heaters are the same. Brand, build quality, and smart features can make a big difference in your daily comfort.

Side-by-side Comparison: Apus Vs Furrion

Understanding specs is good, but seeing the differences side by side makes your decision easier. Here’s a clear comparison of the most important features.

Performance In Real-world Conditions

It’s easy to look at numbers and features, but real-world performance is where you see the real differences.

Water Temperature Stability

Both Apus and Furrion promise consistent hot water, but Furrion’s Vortex technology gives it a slight edge, especially when demand is high (for example, someone is showering while another person runs the kitchen tap). Apus performs well for single-use, but some users notice minor fluctuations with heavy use.

Cold Weather Operation

Both units offer freeze protection, but Apus is often chosen by RVers who travel in very cold areas. Its anti-freeze system is more aggressive, running small cycles to prevent freezing even in harsh conditions. Furrion’s system works well, but some owners recommend extra insulation if you’re camping below 20°F.

Water Pressure Sensitivity

A key area where Apus stands out is the low water pressure start. Many campgrounds have poor pressure, especially when everyone is using water at the same time. Apus heaters can start with as little as 0.4 bar (about 6 psi), while Furrion units need a bit more. If you often camp off-grid or in older parks, Apus is less likely to give you “no hot water” headaches.

Installation And Replacement

Both brands are designed for easy swapping with your old tank heater. However, some users report that Furrion’s units may require minor trim work if your RV cutout is slightly off-standard. Apus is usually a more direct fit, especially in older RVs.

Fuel Efficiency

Both use propane, but Apus tends to use slightly less because of its lower BTU rating and smart sensors. Over a long trip, this can save you a few pounds of propane—a small but real advantage if you’re watching your fuel budget.

Noise Level

Neither unit is loud, but Apus is especially quiet. This matters if you’re running the heater at night or have a small RV where every sound is noticeable.

Cost Of Ownership

Buying a tankless water heater is more than just the sticker price. You should think about:

• Upfront cost: Apus is usually $100–$300 less expensive.
• Installation cost: Both are DIY-friendly, but professional installation adds $150–$400.
• Maintenance: Both brands need periodic descaling and cleaning. Furrion parts are easier to find at dealerships.
• Propane usage: Furrion heats water faster but uses more fuel; Apus is more efficient for low-demand users.
• Warranty service: Both offer similar 2-year warranties. Furrion’s larger support network gives it a slight edge for quick repairs.

Over three years, the total ownership cost is often slightly lower for Apus, unless you need frequent support or parts.

User Reviews: What Real Rvers Say

Online reviews and RV forums can tell you a lot that specs can’t. Here’s what actual users highlight:

Apus Owners

• “Perfect for boondocking—works with weak pressure.”
• “Touchscreen is easy, even for my parents.”
• “Very quiet, never wakes up the kids.”
• “Installation was fast, took about 40 minutes.”
• “Temp is stable unless two people use water at once.”

Furrion Owners

• “Never run out of hot water, even with two showers back to back.”
• “A bit more expensive, but worth it for the features.”
• “Vortex tech really does keep temperature stable.”
• “Support was great when I needed a replacement part.”
• “Slightly louder than my old tank heater, but much faster.”

One non-obvious insight: Some RVers notice that the quality of your RV’s plumbing (especially pipe insulation and diameter) can affect both brands’ performance. If you have very long water lines, you might experience more initial cold water with either heater.

Key Factors To Consider When Choosing

Choosing between Apus and Furrion isn’t just about the name. Think about these key points:

1. How Many People Use Hot Water At Once?

If you have a large family or want to run multiple taps, Furrion’s higher flow and Vortex tech may be better.

2. Do You Often Camp In Cold Weather?

Both have freeze protection, but Apus is often chosen by winter RVers for its aggressive anti-freeze cycles.

3. Do You Struggle With Low Water Pressure?

Apus is the clear winner for off-grid or older campgrounds with weak pressure.

4. Is Brand Support Important?

Furrion has a bigger dealer network and easier access to parts.

5. What’s Your Budget?

Apus is more affordable upfront and uses less propane for low-demand users.

6. Do You Care About Modern Controls?

Both use touchscreens, but Furrion’s panel is more stylish and advanced.

• Noise sensitivity:

Apus is quieter—a small but important factor for light sleepers or compact RVs.

Common Mistakes To Avoid

When upgrading to a tankless water heater, many RVers make these mistakes:

• Ignoring water pressure limits: Make sure your campground or pump can meet the minimum.
• Not insulating pipes: Cold pipes can reduce efficiency and make freeze protection less effective.
• Poor venting: Both units need good venting to avoid dangerous gases inside your RV.
• Skipping regular descaling: Hard water can quickly cause build-up. Flush your heater every few months.
• Expecting instant hot water at the tap: There’s always a short delay for hot water to travel through your pipes—especially in larger RVs.

A less obvious tip: Always check your RV’s electrical system. Both units use 12V DC for ignition and controls, but a weak battery or loose wiring can cause random shutoffs.

Practical Installation Tips

If you’re planning a DIY install, here are some steps and tips for a smooth job:

• Turn off propane and water before you start.
• Remove the old heater carefully; disconnect all gas and water lines.
• Check cutout size. Both Apus and Furrion fit standard 16” x 12” openings, but measure before you buy.
• Install new heater using the supplied gasket and screws.
• Connect water lines and check for leaks.
• Connect propane, using leak detector solution to check for safety.
• Wiring: Both connect to your RV’s 12V system. Double-check polarity and connections.
• Test run before sealing everything up. Watch for error codes on the display.
• Seal exterior edges with waterproof sealant to avoid leaks and drafts.

If you’re unsure, a certified RV technician can usually install a tankless heater in 1–2 hours.
