Why Traditional Heating Systems Fall Short in Small Living Spaces

Traditional heating systems weren’t designed with tiny homes and RVs in mind, which creates several critical limitations. Conventional furnaces and HVAC systems consume valuable square footage—up to 30 cubic feet that could otherwise be used for storage or living space. In compact environments where every inch counts, this spatial inefficiency becomes a major drawback.

Energy consumption presents another significant challenge. Standard heating systems typically require 1200-3500 watts of power, exceeding what most small-space electrical systems can safely deliver, especially when running on limited solar arrays or campground hookups. For mobile tiny homes and RVs, this power demand often means you’ll need to sacrifice other electrical comforts or invest in costly electrical upgrades.

Traditional systems also create problematic heat distribution in small spaces. Without extensive ductwork, you’ll experience uncomfortable hot and cold zones throughout your tiny space—often creating a 10-15°F temperature difference between floor and ceiling. This uneven heating wastes energy and reduces comfort in your limited living area.

Propane Heaters: The Popular Alternative for Off-Grid Living

Propane heaters stand as the backbone of off-grid heating solutions for RVs and tiny homes. They deliver reliable warmth without depending on electrical hookups, making them perfect for boondocking or remote living situations where power access is limited.

Safety Considerations for Propane Heating

Propane heaters require proper ventilation to prevent carbon monoxide buildup. Always install a CO detector within 10 feet of your heater and ensure your space has adequate airflow. Direct-vent models are safest as they pull combustion air from outside and exhaust fumes externally. Never use unvented propane heaters while sleeping, and keep flammable materials at least 3 feet away from all heating surfaces to prevent fire hazards.

Cost-Efficiency and Installation Requirements

A quality propane heater typically costs $200-800, with installation adding another $100-300 if professionally done. The average tiny home or RV uses 1-3 gallons of propane daily during cold weather, costing $3-9 per day at current prices. Installation requires proper clearances (usually 1-2 feet from combustibles), secure mounting, and certified gas line connections. Most units need minimal electricity for ignition and fans, drawing only 2-12 watts, making them compatible with small solar setups.

These efficient units maximize BTU output (3,000-8,000) while minimizing footprint, often requiring just a 12×12-inch hearth pad for installation.

Ventilation and Safety Requirements

Wood stoves require proper clearances—typically 18-36 inches from combustibles—and approved chimney systems. You’ll need to install a double or triple-wall chimney pipe through an approved roof or wall thimble with heat shields. Most tiny home jurisdictions mandate UL-listed stoves and NFPA 211-compliant installations. Always include a carbon monoxide detector and maintain at least 5 inches of clearance between single-wall connector pipes and combustible materials to prevent accidental fires.

Infrared Heating Panels: The Low-Profile Option

Infrared heating panels offer one of the most space-efficient solutions for RV and tiny home dwellers who need warmth without sacrificing precious floor space.

How Infrared Technology Works in Small Spaces

Unlike conventional heaters that warm air, infrared panels emit radiation that directly heats objects and people in the room. This radiant heat works similarly to sunshine, warming surfaces it touches without wasting energy heating the entire air volume. In compact spaces of 100-400 square feet, infrared panels distribute heat evenly with minimal temperature stratification. You’ll experience consistent comfort from floor to ceiling—eliminating those cold spots common with forced-air systems.

Installation and Energy Consumption

Infrared panels mount directly on walls or ceilings, requiring just 1-2 inches of depth and standard 120V outlets. Most panels draw between 300-800 watts—significantly less than traditional heaters—making them compatible with solar setups and limited electrical systems. A 400W panel can effectively heat approximately 100 square feet of well-insulated space. Installation is typically DIY-friendly with basic mounting hardware, allowing you to position panels strategically throughout your tiny living space for zoned heating capabilities.

Diesel Heaters: Powerful Heating for Colder Climates
