Gasland MHA18BN Propane Radiant Heater

Gasland’s MHA18BN is a compact propane radiant heater intended for well-ventilated spaces such as garages or workshops, but it’s commonly adapted by RV users who need portable warmth when hookups aren’t available. It features safety shut-offs for tip-overs and low oxygen to reduce risk in mobile environments. The unit operates without electricity, relying on a 20 lb LP cylinder, which can help reduce dependence on shore power during travel or outages. Built-in mobility with wheels and a handled design makes it easy to relocate. The cabinet conceals the propane tank for a cleaner look.
Key considerations:
- Energy independence: No electricity needed; suitable for off-grid scenarios.
- Safety: Tip-over and low-oxygen shut-off features add basic protection in mobile settings.
- Mobility: Portable design helps you move heat to where it’s needed most.
Ideal uses include small shops, semi-enclosed spaces, or temporary camping setups where a portable propane heat source is preferred. Always ensure adequate ventilation and follow all safety instructions for propane appliances in an RV environment.

Buying Guide: Key Purchase Considerations for RV Gas Heaters
- Heater type: Evaluate whether you prefer on-demand tankless models for continuous hot water, traditional tank heaters for established systems, or portable propane radiant units for supplemental warmth. Tankless units typically offer efficiency and reduced propane use, while tank heaters provide steady storage hot water.
- BTU output and capacity: Choose BTU ratings appropriate for your RV size and climate. Higher BTU is beneficial in colder environments, but oversizing can waste energy. For water heaters, consider desired GPM and the ability to maintain stable temperatures at altitude.
- Power source and reliability: Gas-only units are advantageous where electricity is scarce, but hybrids offer flexibility when both power sources are available. Consider the availability of electrical hookups, generator access, or off-grid scenarios.
- Ventilation and safety: Venting requirements vary by model. Ventless options require careful interior layout and ventilation in some cases. Always install according to manufacturer instructions and follow propane safety guidelines, including CO alarms and proper clearances.
- Durability and maintenance: Look for corrosion protection, anode rods, replaceable parts, and ease of maintenance. Porcelain-lined tanks and accessible service components extend lifespan in mobile environments.
- Altitude performance: If you travel to high elevations, select units designed to operate efficiently at altitude to prevent reduced combustion efficiency and propane waste.
- Remote monitoring and controls: Features such as smart remotes or real-time gas usage display add convenience and can help manage propane consumption during trips.
- Installation compatibility: Check mounting options, fit in your RV’s allotted space, and whether the heater can replace existing units or requires adapters or specific door kits.
With the right considerations, you can select an RV gas heater that delivers safe, reliable warmth across diverse trips, from winter getaways to extended stays in cooler climates. Always prioritize safety, ventilation, and compatibility with your RV’s electrical and plumbing systems when choosing a heating solution.
