Mr. Heater MH9BXRV Buddy Portable RV Radiant Heater
Type: Propane radiant space heater designed for RV and indoor use. Output: 4,000–9,000 BTU for spaces up to 225 sq ft. The unit is described as nearly 100-percent efficient with clean-burning operation.
Safety features include auto shut-off if tipped over, pilot light failure, or low-oxygen sensing. The manufacturer notes potential altitude sensitivity (may shut off above 7,000 ft). This heater provides direct radiant warmth suitable for small RV cabins and intermittent use where propane is available.
Caframo True North Low Profile Electric Heater
Type: Electric space heater with adjustable thermostat and multiple fan/heat settings. The unit offers five settings including steady heat and high output for circulation.

Key features include a built-in anti-freeze setting that turns on automatically below 38°F (3°C) to protect stored spaces, and a solid steel housing suited to compact storage. This model is a practical option when shore power or inverter capacity supports electrical heating and when quiet operation is desired.
RecPro RV Tank Heater Pad For Fresh/Grey/Holding Tanks
Type: Peel-and-stick heater pad for water tanks. Size indicated: 12″ x 18″. Designed for fresh water, grey water, or holding tanks up to 50 gallons.
The pad activates when water temperatures drop below 45°F (5°C) and maintains a target of approximately 68°F (20°C). The adhesive backing allows attachment to most tank surfaces. This product focuses on preventing frozen lines and maintaining flow in cold conditions.
GIRARD Tankless RV Water Heater 12V, 42,000 BTU
Type: On-demand tankless water heater running on 12V control and LP gas. Rated at 42,000 BTU with an onboard microprocessor and digital user control panel.

Features include consistent temperature regulation through monitoring of inlet temperature and flow rate, quiet brushless motor operation, and high efficiency—advertised as consuming roughly half the LP of a comparable 6-gallon tank for the same hot water output. This model targets continuous hot water needs without a storage tank.
Ficstar 15FT Heated Drinking Water Hose For RVs
Type: Heated drinking-water hose with self-regulating thermostat. Length: 15 ft. Inner diameter: 5/8″ with 3/4″ GHT adapter. Rated to remain antifreeze to -45°F.
Construction notes emphasize food-grade materials that avoid odors or harmful chemicals, leak-proof washers, and improved thermal conductivity with internal heated copper wiring. This hose is intended to keep water lines open and safe for consumption in sub-freezing conditions.
Buying Guide: How To Choose The Right RV Heater Options
Selecting the best heating solution for an RV involves assessing cabin heating, water heating, and freeze protection. Below are purchase considerations and comparison perspectives to help match products to needs.
Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Types Of Heating And When To Use Them
- Portable Propane Space Heaters: Good for quick, high-BTU spot heating in small RVs or when off-grid. Consider ventilation, safety sensors, and altitude limitations.
- Electric Space Heaters: Best when connected to shore power or a robust inverter. They offer quiet operation, antifreeze modes, and easy installation but rely on electrical capacity.
- Tank Heater Pads & Heated Hoses: Designed to protect water systems from freezing. Pads stick to tanks; heated hoses protect supply lines—both are preventative rather than primary cabin heat sources.
- Tankless Water Heaters: Provide continuous hot water without a storage tank. Look for BTU rating, control options, and efficiency for family-sized hot water needs.
Key Specifications To Compare
- BTU Output: Higher BTU produces more heat; match to RV interior volume. Example: 4,000–9,000 BTU suits small cabins; 42,000+ BTU applies to water heater demand, not space heating.
- Power Source: Propane, 12V control with LP burner, or pure electric. Confirm availability of fuel and inverter/shore power capacity.
- Safety Features: Tip-over shutoff, low-oxygen sensors, overheat protection, and certifications for indoor use.
- Altitude Performance: Some propane burners may shut down above certain elevations. If you travel high, choose models rated for altitude or with high-altitude modes.
- Efficiency & Fuel Use: For tankless water heaters, check claimed LP consumption and whether the product reduces gas use versus tank heaters.
- Thermostat & Controls: Adjustable thermostats, antifreeze modes, and digital control panels improve usability and protect systems during storage.
Installation & Maintenance Considerations
- Space Heater Placement: Ensure clearances, secure mounting for mobile use, and easy access to shutoff valves for propane units.
- Tank Pads & Hoses: Adhesive pad placement should match tank geometry; heated hoses require proper connectors and may need a dedicated power source.
- Tankless Heater Fit: Confirm door size and rough-in compatibility if replacing a factory unit. Some tankless models list required door openings and optional door kits.
- Anode Rods & Corrosion Prevention: For tank systems, routine inspection and replacement of anode rods prolong tank life. Selecting the correct rod type and size for the make/model is important.
Safety And Cold-Weather Strategy
- Layered Protection: Combine cabin heat (space heater) with tank pads and heated hoses to prevent frozen lines and ensure hot water availability.
- Power Redundancy: For winter camping, plan fuel and electrical redundancy—propane heaters plus a battery/inverter for pumps and controllers is a common approach.
- Monitor And Sensors: Low-oxygen and CO detectors are mandatory when using combustion heaters inside confined RV spaces. Use certified units and follow ventilation guidelines.
Practical Comparison Perspectives
- Off-Grid Use: Propane radiant heaters and tankless LP water heaters offer autonomy from shore power; evaluate BTU, tankless flow rate, and fuel consumption.
- Shore Power / Winter Storage: Electric heaters with antifreeze settings excel for stored RVs or while connected to power. Tank pads and heated hoses protect plumbing regardless of heating source.
- Family/High-Demand Hot Water: Tankless units with higher BTU (40k+ range) deliver continuous hot water; confirm GPM (gallons per minute) rating for simultaneous showers.
- Budget vs Long-Term Value: Initial cost, installation complexity, and maintenance (anode rod replacement, venting, filters) affect lifecycle costs and convenience.
Checklist Before Buying
- Measure interior volume and identify where heat is needed most.
- Confirm available power sources (propane, shore power, inverter capacity, 12V supply).
- Verify installation space, venting needs, and door/opening compatibility for water heaters.
- Prioritize safety certifications and built-in safety cutoffs for combustion heaters.
- Plan for freeze protection: tanks, supply hoses, and system controls.
