GASLAND vs OEVANT Spec Comparison
Flow Rate
The OEVANT unit delivers up to 3.9 GPM of continuous hot water, while the GASLAND model provides 1.58 GPM. This means the OEVANT can supply roughly 2.5 times more water per minute. For users who need back-to-back showers or are rinsing off gear after outdoor activities, the higher flow rate of the OEVANT is a significant practical advantage. The GASLAND flow rate is sufficient for single-fixture use, such as a single shower or sink, but it will not support higher demand scenarios as effectively as the OEVANT. Higher GPM generally means faster filling and better pressure for multiple outlets.
Power Output
OEVANT features a 55,000 BTU output, whereas GASLAND offers 41,000 BTU. The higher BTU rating on the OEVANT contributes to its ability to heat water more rapidly and sustain higher flow rates. This power difference is relevant when you need a quick temperature rise, especially in colder ambient conditions. The GASLAND unit achieves a maximum temperature rise of 109.4°F, which is capable, but the OEVANT’s higher input allows for greater flexibility in heating performance. If you prioritize rapid heating and consistent hot water delivery during high-demand usage, the OEVANT’s superior BTU rating provides a clear edge in raw heating capacity.
Voltage
The GASLAND heater runs on two D-cell batteries for its electronic ignition, while the OEVANT requires 12V DC power. This distinction affects how you power the unit in off-grid scenarios. The GASLAND model allows for portable use without needing a vehicle or shore power connection, relying solely on disposable batteries for ignition. In contrast, the OEVANT needs a 12V DC source, which is standard in most RVs and vans but requires a connection to a vehicle battery or inverter. If you plan to use the heater in locations without electrical access, such as remote camping sites, the GASLAND battery operation offers greater independence from vehicle power systems.
Temperature Control
OEVANT provides precise digital temperature control, allowing you to set the water temperature anywhere from 95°F to 123°F with an accuracy of ±1°F. The GASLAND unit features an LED digital display for temperature readout but does not specify adjustable temperature settings in the provided data. Precise control is valuable for preventing scalding and ensuring consistent comfort, particularly for children or sensitive skin. The OEVANT’s ability to maintain a steady temperature within a narrow range reduces the need for manual mixing valves. If you want exact temperature management without guesswork, the OEVANT’s advanced control system is the superior choice.
Installation Location
The GASLAND BE158 is designed for portable outdoor use, while the OEVANT is built for standard 16x16 inch RV cutouts. The GASLAND unit is splash-proof and intended for temporary setups like camping or washing pets, though it should be stored indoors during rain or winter. The OEVANT is a permanent fixture for motorhomes and travel trailers, featuring a forced exhaust fan and designed for retrofitting into existing RV structures. Your choice depends on whether you need a mobile, temporary solution or a fixed installation for your vehicle. The OEVANT offers a more integrated and protected installation method for RV life, while GASLAND offers flexibility for temporary outdoor tasks.

RV owners needing high flow for showers
The OEVANT unit delivers up to 3.9 GPM, which is more than double the GASLAND output. Its 55,000 BTU burner heats water quickly. The digital panel allows precise temperature control within ±1°F. This high flow rate supports back-to-back showers for families or groups in an RV setting.
Campers needing portable outdoor hot water
The GASLAND model is designed for portable outdoor use. It starts with just 3.6 PSI of water pressure, making it suitable for low-pressure sources. It runs on a standard 20 lb propane tank and uses D-cell batteries for ignition. Its compact size fits easily in camping gear or small cabins.
Users wanting simple temperature monitoring
The GASLAND unit features an LED digital display that shows the water temperature clearly. This helps you avoid water that is too hot or cold. It lacks complex staging but offers straightforward monitoring. The CSA certification ensures it meets safety standards for both Canadian and US markets during use.
RV owners wanting remote control convenience
The OEVANT heater includes a remote control for adjusting settings from a distance. This is useful in tight RV spaces. It also features a forced exhaust fan and error codes for easy troubleshooting. The 12V DC power draws from your RV battery, keeping the system integrated with your vehicle's electrical setup.
