Gasland vs Westinghouse Tankless Comparison
Fuel Type
The GASLAND BE158 runs on propane, connecting to a standard 20 lb liquid propane tank. This makes it ideal for off-grid scenarios, camping, or RVs where grid power is unavailable. It uses electronic ignition powered by two D-cell batteries. In contrast, the Westinghouse unit is electric, requiring a 240V power source. It needs three 40-amp double-pole breakers and 8 AWG wire for proper installation. You must have access to household electricity to use this model. If you need portable heat away from the grid, the propane option is the clear choice. For home installations with existing electrical infrastructure, the electric model is the standard solution.
Flow Rate
Capacity differs significantly between these two units. The GASLAND BE158 provides 1.58 gallons per minute (GPM). This output is sufficient for a single sink or shower but may struggle if multiple fixtures run simultaneously. The temperature rise varies from 55.4°F to 109.4°F depending on the inlet water temperature and flow. The Westinghouse heater offers a maximum flow rate of 5.55 GPM. It starts flowing at just 0.79 GPM, ensuring instant heat activation. This higher capacity allows you to comfortably use a shower and a sink at the same time without pressure drops or temperature fluctuations. For whole-house demand, the electric model handles the volume much better.
Installation Location
These heaters are designed for different environments. The GASLAND BE158 is built for outdoor use. It is splash-proof and can handle light drizzle, but prolonged rain exposure will damage internal components. You should store it in a dry place and drain it for winter. The Westinghouse model is designed for indoor residential use. It mounts flush against a wall, saving floor space in apartments, homes, or offices. Its compact dimensions of 17 inches high by 13 inches wide and 4.3 inches deep allow it to fit in utility closets or under sinks. You cannot use the Westinghouse unit outdoors, while the GASLAND unit is not meant for permanent indoor plumbing.
Smart Features
Control methods vary between the two devices. The Westinghouse heater includes built-in Wi-Fi connectivity. You can adjust the temperature remotely via a mobile app or use voice commands with Alexa and Google Home. This integration suits modern smart homes where you want to monitor usage and settings from anywhere. The GASLAND BE158 lacks any smart connectivity or app support. It features an LED digital display that shows the current power and temperature readout. You control it manually using the physical on/off switch and temperature dial. If you prefer remote monitoring and voice control, the Westinghouse model is superior. For simple, direct manual control, the GASLAND unit is sufficient.
Dimensions
Size and footprint matter for placement. The GASLAND BE158 measures 17.3 inches in height, 6.1 inches in width, and 11.8 inches in length. It is a portable unit that can be moved between locations like a cabin or a campsite. The Westinghouse unit is slightly taller at 17.1 inches but much wider at 13 inches. However, it is significantly thinner at only 4.3 inches deep. This slim profile allows it to mount flush against a wall, taking up zero floor space. The GASLAND unit is bulkier in width but thinner in depth. For permanent indoor installations where wall space is limited, the Westinghouse design is more space-efficient.
Which tankless heater fits your needs
Off-grid camper or RV owner
The GASLAND unit runs on propane and requires no grid power. It starts with just 3.6 PSI of water pressure, making it ideal for low-pressure setups in RVs or cabins. Its compact size fits small spaces, and the LED display lets you monitor temperature easily while you are away from home.
Homeowner with 100A electrical capacity
This Westinghouse model delivers up to 5.55 GPM for whole-house use. It requires a 240V connection and three 40-amp breakers. The high flow rate supports simultaneous shower and sink use. Its slim 4.3-inch depth saves wall space, and WiFi control allows remote temperature adjustments via voice commands or an app.
User needing smart home integration
You can control this electric heater remotely through WiFi. It works with Alexa and Google Home for voice commands. You can adjust settings from anywhere. The unit provides instant hot water with a low starting flow of 0.79 GPM. This connectivity makes it a practical choice for modern smart home setups.
