Detailed Reviews
1. Camplux 5L Outdoor Propane Tankless Water Heater
The Camplux 5L has earned its place as the benchmark for van life propane water heaters. At 37,000 BTU, it heats water efficiently for outdoor showers, dishwashing, and sink use. The unit features electronic ignition powered by two D-cell batteries, so you never need to fiddle with a pilot light. The modulating gas valve adjusts the flame automatically based on water pressure, which means consistent temperatures even when your water supply pressure fluctuates — a common issue with van pumps. Installation is straightforward: connect to your propane line, hook up a garden hose or 12V pump, and you’re set. The unit is rated for outdoor use and vents combustion gases downward, which is important when mounting it in a van with ventilation considerations.
Pros: CSA-certified safety systems, modulating valve for consistent temps, simple D-battery ignition, compact footprint. Cons: Not rated for indoor use without additional ventilation precautions, flow rate may feel low for high-pressure shower heads.
2. Gasland Outdoors BE158 Propane Tankless Heater
The Gasland BE158 is the power user’s choice among on-demand propane heaters for van life. The 58,000 BTU output translates to 1.58 GPM of hot water, which is noticeably better for full showers after a long overlanding day. The digital LCD panel lets you dial in your exact target temperature in degrees, taking the guesswork out of adjusting the gas valve. Gasland’s overheat protection, flame failure shutoff, and anti-frost system add layers of safety for year-round van use. The unit hooks up to standard 3/8″ NPT fittings and works with any 20 or 30 lb propane tank. Build quality is excellent — the stainless steel burner housing is noticeably more robust than budget competitors.
Pros: Highest BTU output in its class, digital LCD temperature precision, durable stainless steel construction, comprehensive safety shutoffs. Cons: Larger and heavier than the Camplux 5L, higher price point reflects premium build.
3. Eccotemp L5 Portable Propane Tankless Water Heater
For van lifers on a tight budget or those who want a minimalist no-frills setup, the Eccotemp L5 delivers. At just 7.3 lbs, it’s the lightest option in this roundup and comes ready to use with a shower head and hose included. The piezo ignition fires from a standard 1 lb propane canister or a larger 20 lb tank with an adapter. While its 1.4 GPM flow rate is comparable to pricier models, the L5 lacks the digital controls and stainless burner of higher-end units. That said, for casual van travelers who shower a few times a week rather than daily, the L5 is an outstanding value that holds up well over time.
Pros: Ultra-lightweight at 7.3 lbs, shower accessories included, no electricity needed, works with 1 lb or 20 lb propane. Cons: Manual temperature adjustment only, no digital display, less durable long-term than premium options.
4. Camplux AY132 Propane Water Heater with Digital Control
The Camplux AY132 bridges the gap between budget and premium. It adds a digital LCD display and a remote control to the trusted Camplux platform, allowing you to adjust temperature without stepping outside your van. At 34,000 BTU it’s slightly lower output than the 5L, but the temperature precision and remote operation make it a favorite for permanent van builds where convenience matters. The unit mounts vertically and features a sleek cabinet-style housing that integrates cleanly into van wall panels.
Pros: Remote control operation, digital temperature display, clean cabinet-style housing for van integration. Cons: Lower BTU than BE158, requires 110V for the digital controls in some configurations.
Buyer’s Guide
BTU Output and Flow Rate
BTU output directly determines how fast and how hot your water gets. For a comfortable outdoor shower, look for a minimum of 37,000 BTU with at least 1.3 GPM. Higher BTU units like the Gasland BE158 at 58,000 BTU can maintain temperature better in cold climates or when drawing water from a cold freshwater tank. If you’re using a low-pressure 12V water pump, make sure your heater’s minimum activation flow rate (typically 0.66 GPM) is achievable with your pump.
Ignition Type and Power Source
Most van propane water heaters use battery-powered electronic ignition (2× D-cell batteries), which is reliable and doesn’t draw from your van’s electrical system. Some premium models use a piezo ignition that requires no batteries at all. Avoid propane heaters that require 110V AC power unless you have a robust inverter, as this adds complexity to your electrical system and creates dependency on shore power or a large battery bank.
Safety Certifications and Shutoff Features
Look for CSA or ETL certification, which confirms the heater meets North American safety standards. Essential safety features include flame failure shutoff (gas cuts off if the flame goes out), overheat protection, and anti-frost mode for cold weather use. Units without these certifications may be cheaper but carry real risks in enclosed van spaces where propane leaks can be deadly. Never operate any propane appliance without ensuring adequate ventilation in your van build.
Frequently Asked Questions
Can I use a propane tankless water heater inside my van?
Most models in this review are rated for outdoor use only and produce carbon monoxide as a combustion byproduct. If you want to mount one inside a van, you must install a sealed combustion system with external air intake and exhaust venting, similar to an RV-style water heater installation. Always follow manufacturer guidance and local safety codes when installing any propane appliance in an enclosed vehicle.
What size propane tank do I need?
A 20 lb propane tank (the standard BBQ-style tank) is the most practical choice for van life. At moderate use (one 5–8 minute shower per day), a 20 lb tank typically lasts 7–10 days depending on BTU output. Many van lifers carry two 20 lb tanks in an external propane locker for extended trips between refills.
Do I need a 12V pump with a propane water heater?
Yes, unless you’re gravity-feeding water from an elevated tank, you’ll need a 12V water pump to meet the minimum activation flow rate of your heater (typically 0.4–0.66 GPM). A standard Shurflo or Seaflo 12V pump works well with all the models reviewed here. Make sure your pump is paired to a pressure accumulator tank to smooth out pulsing flow for consistent heater activation.
How long does installation take?
A basic outdoor-mounted propane water heater installation typically takes 2–4 hours for someone with basic DIY skills. You’ll need to run a propane line with appropriate fittings, connect water inlet/outlet hoses, and mount the unit securely. More complex permanent installations with interior mounting, dedicated propane lockers, and integrated shower enclosures can take a full weekend build day.
Final Verdict
The Camplux 5L is our top pick for most van lifers — it offers the best combination of output, safety features, and price for typical on-the-road use. If you want more power and don’t mind spending more, the Gasland BE158’s 58,000 BTU output and digital controls are worth the upgrade for full-time van dwellers. Budget-conscious builders who shower occasionally will find everything they need in the Eccotemp L5 at a fraction of the price. Whichever van propane tankless water heater you choose, prioritize safety certifications and proper ventilation planning above all else.
