GASLAND BE158B Portable Tankless Water Heater, 1.58 GPM, 41,000 BTU

For a hot shower at a campsite or a rinse after washing a vehicle, the GASLAND BE158B provides on-demand propane hot water in a portable format. Its 1.58 GPM flow rate and 41,000 BTU output suit outdoor and mobile uses. A digital display makes the water temperature easy to read.

Key points

This tankless heater has a 6 L capacity and runs on liquid propane. It is designed for use with a standard 20 lb. propane tank, while its electronic ignition is powered by two D-cell batteries. That combination makes it practical for outdoor settings without a mains electrical connection. The stated water-pressure range is 3.6–110 psi, and the unit can start at low water pressure.

Protection features include safeguards for low water flow, dry combustion, flame failure, high water pressure, overheating and freezing. The unit is CSA certified. Its stainless steel construction and black finish complete a portable setup intended for outdoor use. Buyers often highlight portability, ease of use and quick heating, feedback is mixed on reliability and water pressure, with some raising concerns about durability and leakage.

How it fits

The BE158B is suited to camping, RV trips, hunting and other off-grid routines where hot water is useful but a fixed household heater is not. It can also serve practical tasks such as rinsing pets or horses, washing dishes, cleaning a vehicle, or providing hot water at a cabin, greenhouse or tiny home. The supplied shower head supports showering, while the 1.58 GPM flow rate gives a clear guide to the water delivery to expect when choosing a portable heater.

Compared with a fixed tank-style installation, this portable tankless format is designed to bring hot water to an outdoor or mobile setup. It makes sense when mobility and propane operation are more important than a permanent household installation. Use it outdoors, and keep it in a dry place: it can handle splashes and a little drizzle, but prolonged exposure to rain or water can damage internal components.

How to use it

Connect the heater to its propane supply and water source, then use the digital display to monitor the temperature. The heater’s maximum output is 41,000 BTU per hour, with a stated temperature rise from 55.4°F (13°C) to 109.4°F (43°C) at 1.58 GPM. Actual water temperature depends on the incoming water and operating conditions, so the display is useful for adjusting the setup to the task.

Check for gas leaks before operation. Do not wrap Teflon tape between the gas regulator and the gas inlet pipe. For winter storage, disconnect the drain plug to drain the water, then store the heater in a warm, dry place. These steps help make setup and seasonal care part of a straightforward portable hot-water routine.
