Who it fits

Key specs explained for this unit

Flow Rate: 1.58 GPM

This unit delivers 1.58 gallons of hot water per minute. This flow is sufficient for a single shower or handwashing. It is not high enough to support two simultaneous fixtures. You should compare this with whole-home units that offer 4 to 8 GPM. This spec suits solo campers or RV travelers who need basic hot water access without complex plumbing setups.

BTU: 41,000 BTU/hr

The heater generates 41,000 British Thermal Units per hour. This power level determines how quickly the water heats up. It allows for a temperature rise of up to 109.4 degrees Fahrenheit at the stated flow rate. This is standard for portable propane heaters. You can compare this to larger indoor units that may offer higher outputs for multiple bathrooms.

Dimensions: 17.3 x 6.1 x 11.8 inches

The unit measures 17.3 inches in height, 6.1 inches in width, and 11.8 inches in length. This compact footprint makes it easy to store in an RV cabinet or carry on camping trips. It is significantly smaller than permanent indoor tankless heaters. You should measure your storage space before purchasing to ensure it fits comfortably in your vehicle or cabin.

Fuel Type: Propane

This heater runs on standard 20 lb liquid propane tanks. This fuel source is widely available at most outdoor retailers. It allows for true off-grid operation without needing electrical hookups for gas combustion. You can compare this to electric models that require a dedicated circuit. Propane is ideal for remote locations where power access is limited or non-existent.

Design and build details

The GASLAND BS158 is a compact unit designed for outdoor mobility. According to the listing, its dimensions are 17.3 inches in height, 11.8 inches in length, and 6.1 inches in width. This small footprint allows you to store it easily in an RV compartment or a camping gear bag. The white finish is splash-proof, which helps it handle light drizzle during use. However, the listing notes that prolonged exposure to rain can damage internal components. You should store the unit in a dry place when not in use.

The device runs on a standard 20 lb liquid propane tank. It features electronic ignition powered by two D-cell batteries. This setup means you do not need external power sources to start the heater. The layout includes a garden hose adapter and a five-foot on/off switch shower head in the box. This makes initial setup straightforward for camping or cabin use. The unit requires only 3.6 PSI of water pressure to start, which is helpful for low-pressure sources.

Safety features are integrated into the build. The listing highlights over-heating protection, low water flow protection, and dry combustion protection. It also includes anti-freezing protection and a flame failure device. These systems are CSA certified for Canadian and US standards. You should note that the unit is not suitable for high altitude areas over 3300 feet or strong wind conditions. This limits where you can safely operate it outdoors.

Setup and Everyday Use Guide

Setup begins with connecting the unit to a standard 20-pound liquid propane tank. The listing includes a CSA-certified gas regulator and hose for this connection. You must ensure the seal is tight to prevent gas leakage, but do not use Teflon tape between the regulator and the gas inlet pipe. The unit requires two D-cell batteries to power its electronic ignition. You also connect a garden hose to the water inlet. The heater starts with low water pressure, needing only 3.6 PSI to activate. This makes it compatible with most standard outdoor spigots or RV water supplies.

In daily use, the BS158 provides hot water at a maximum flow rate of 1.58 gallons per minute. The temperature rise varies based on input water temperature, ranging from a 55.4-degree increase at the lowest setting to 109.4 degrees at the highest. You can adjust the output by controlling the water flow. The unit is designed for outdoor scenarios such as camping, RVing, or washing vehicles. It is splash-proof and can handle light drizzle, but you should store it in a dry place to protect internal components. Do not use it in strong wind conditions or at altitudes over 3,300 feet, as performance may suffer. For winter storage, you must drain the water by disconnecting the drain plug to prevent freezing damage. The included five-foot on/off switch shower head allows for convenient operation. Always check for gas leaks before turning the unit on. The built-in safety systems, including over-heating and dry combustion protection, monitor conditions automatically. You rely on these features to maintain safe operation during your outdoor activities.

Before You Buy This Unit

You need a standard twenty-pound propane tank to operate this heater. The listing includes a CSA-certified regulator and hose, so you do not need to purchase separate gas components. You must also connect a garden hose for water supply. The unit requires a low water pressure of 3.6 PSI to start. Keep in mind that it is not suitable for altitudes above 3300 feet or strong wind conditions. You should store it in a dry place to protect internal components from rain damage. Drain the water via the drain plug during winter months to prevent freezing. This portable model fits well alongside fixed indoor units for temporary needs. It suits camping or RV trips where grid power is unavailable. It does not replace a whole-home system for daily indoor use. Check your altitude and weather conditions before relying on it for essential hot water.

Check before you buy

• Verify your altitude is below 3300 feet for proper operation.
• Ensure you have a standard twenty-pound liquid propane tank ready.
• Check that your water pressure meets the 3.6 PSI minimum.
• Confirm you have a dry storage location for winter maintenance.
