Heat Storm Infrared Wall Mounted Heater
The Heat Storm HS-1500-PHX-WIFI is a compact infrared heater designed for wall mounting, preserving floor space in tight RV areas. It includes Wi-Fi connectivity for remote temperature control via a smartphone and a touch screen thermostat for quick adjustments. A tip-over safety shutoff adds a layer of protection in uneven spaces, and a remote is included for convenience. This model suits basement or underfloor zones where wall access is available and space is at a premium.
Key considerations:
– Wall-mounted design minimizes floor usage, ideal for tight basements or underbelly pockets.
– Infrared heating provides direct warmth to objects and people without overheating the entire space.
– Wi-Fi control supports integrated RV smart-home setups, helpful for monitoring temperatures remotely during cold readiness checks.
Dr Infrared Heater Portable Space Heater
The Dr Infrared Heater is a portable option that blends infrared quartz heating with a PTC element, designed to deliver strong warmth in larger areas. It includes Auto Energy Saving mode and a 12-hour timer, which can be useful for pre-warming basement compartments before travel. Safety features include tip-over and overheat protection, while the integrated remote allows operation from a distance. The dual heating system aims for higher perceived warmth with lower energy use.
Key considerations:
– Well-suited for temporary basements or storage areas where a portable unit is preferred.
– High BTU output supports quicker warming of larger or poorly insulated sections.
– Noise is kept low with a quiet blower, aiding in a comfortable environment inside the RV.
GiveBest Smart Wall Heater
The GiveBest Smart Wall Heater offers a 1500-watt capacity with Wi-Fi, a remote, and a touchscreen thermostat. It supports voice control via Alexa, which can integrate into an RV’s smart system. The heater can be mounted on the wall or used with its standing base for floor placement, making it flexible for various basements or engine bays where a stable, compact heat source is needed. It provides three heating modes and a 24-hour timer for scheduled warmth in cold environments.
Key considerations:
– Flexible mounting options help fit irregular RV basements or engine areas.
– Smart features enable remote management when you’re away or inside the living quarters.
– Quick warm-up is expected with 1500W output, suitable for small-to-medium enclosed spaces.
FOGATTI RV Furnace 35,000 BTU Complete Unit
The FOGATTI 35,000 BTU RV furnace is a full unit that includes the motor, chamber, housing, and thermostat. This is designed for rapid and comprehensive heating in camper, motorhome, and travel trailer configurations. It offers multiple heat modes (quick heat, standard, and sleep) with a fault monitor, enabling easier troubleshooting on the road. This complete furnace is ideal for full basements or underbelly compartments where a dedicated RV furnace is appropriate and a full installation is feasible.
Key considerations:
– Complete furnace kit reduces setup complexity for RVs with larger basements or engine bays.
– High BTU output supports rapid warming in colder climates or during winter storage.
– Built-in fault monitoring aids maintenance and operational reliability on extended trips.
Xtreme Heaters Engine Compartment Heater
The Xtreme Heaters unit is designed for engine compartments, bilges, and other underbelly spaces. It uses a self-regulating PTC element and a durable anodized housing with a sealed electronics module and a waterproof fan. It’s compact enough to be mounted in various orientations, including upside down, which can be advantageous for irregular RV layouts. A 150W rating focuses on maintaining temperatures to prevent freezing in critical areas.
Key considerations:
– Self-regulating heat source reduces risk of overheating in enclosed spaces.
– Durable construction suitable for exposure to moisture and vibration in RV environments.
– Flexible mounting orientation supports non-standard basements or compartments.
Buying Guide: Key Purchase Considerations
- Heat source type: Infrared vs forced-air. Infrared feels warmer to occupants directly and is efficient for small to mid-sized spaces; forced-air is better for larger areas or where you need quicker, even distribution.
- Mounting location: Wall-mounted options save floor space, while portable units offer flexibility. For RV basements or engine bays, consider accessibility for venting or heat distribution and the risk of heat damage to surrounding components.
- Control features: Wi-Fi, smart home compatibility, remote control, and programmable timers improve convenience and energy management in off-grid scenarios.
- Safety features: Look for tip-over protection, overheat protection, auto shut-off timers, and proper certifications for RV use and electrical compatibility.
- Power and fuel considerations: Ensure electrical service in your RV matches the heater’s wattage, or verify propane-based or dual-fuel options if you travel with limited power.
- Installation requirements: Complete furnace kits may require professional installation, especially for vented or gas-powered models. Evaluate the complexity against your DIY capability.
- Space and climate needs: For severe cold climates or long-term storage, a dedicated RV furnace or high-output heater may be more reliable; for intermittent use, a portable infrared heater can be sufficient.
- Maintenance: Check for ease of filter replacement, thermostat calibration, and accessibility for routine checks in tight spaces.
- Durability: RV basements and underbelly areas can be rugged; look for corrosion-resistant housings and sealed electronics to withstand moisture and vibration.
