Tiny House Propane Heaters

Tiny House Propane Heaters

Heating a tiny house efficiently and safely is one of the most important considerations for comfortable small-space living. Propane heaters have emerged as a popular solution due to their efficiency, affordability, and relatively low environmental impact. This comprehensive guide explores everything you need to know about propane heaters for your tiny house, from types and installation to safety considerations and cost analysis.

Introduction to Tiny House Heating

Heating a tiny house presents unique challenges due to limited space and often off-grid or mobile living situations. Propane heaters have become a go-to solution for many tiny house dwellers because they provide reliable heat without requiring electricity, making them ideal for off-grid situations. They’re also relatively compact, efficient, and can be more affordable than electric heating systems in the long run.

Key Terms:

  • BTU (British Thermal Unit): The measurement of heat output for heaters
  • Direct Vent: Heaters that draw air from outside and exhaust combustion gases outside
  • Ventless/Vent-free: Heaters that don’t require external venting but may introduce moisture into your space
  • Thermostat: Device that regulates temperature by controlling the heater

Types of Propane Heaters for Tiny Houses

Direct Vent Wall Heaters

Direct vent heaters like the Williams 22000 BTU model are popular choices for tiny houses. These units mount on an exterior wall and vent directly outside, making them safe and efficient options. The Williams model, as mentioned by a tiny house owner on Reddit, includes a built-in thermostat and piezo ignition system (which doesn’t require electricity to light).

Benefits include:

  • No electricity required for basic operation
  • Clean burning with combustion gases vented outside
  • Relatively simple installation
  • Available in various BTU ratings to match your space

Marine-Style Heaters

The Dickinson heater, used by Tumbleweed Tiny Houses, is a marine-style propane heater originally designed for boats. These compact units offer both functionality and aesthetic appeal, often resembling small fireplaces. They’re well-suited for the limited space in tiny houses and provide efficient zone heating.

Features include:

  • Attractive design that serves as a focal point
  • Compact size perfect for tiny spaces
  • Reliable heat output
  • Designed for small spaces like boats and tiny houses

Installation Considerations

Installing a propane heater in a tiny house requires careful planning:

  • Location: The heater should be positioned where it can distribute heat effectively throughout your space while meeting clearance requirements for safety.
  • Venting: Direct vent heaters require access to an exterior wall for proper venting.
  • Propane Supply: Consider where your propane tank will be located and how it will connect to your heater.
  • Building Codes: Even in tiny houses, following applicable building codes for gas appliance installation is essential for safety and insurance purposes.

Many tiny house owners opt for professional installation of propane heaters to ensure safety and proper functioning, though DIY installation is possible with the right skills and knowledge.

Efficiency and BTU Requirements

Determining the right size heater for your tiny house is crucial. Too small, and you’ll be cold; too large, and you’ll waste fuel and money.

A general rule of thumb for calculating BTU requirements:

  • For well-insulated tiny houses: 20-30 BTU per square foot
  • For moderately insulated tiny houses: 35-45 BTU per square foot
  • For poorly insulated tiny houses: 50+ BTU per square foot

For example, a well-insulated 200 square foot tiny house would need approximately 4,000-6,000 BTU, while the same house with poor insulation might require 10,000+ BTU.

Safety Considerations

Safety is paramount when using propane heaters in small spaces:

  • Carbon Monoxide Detection: Always install carbon monoxide detectors in your tiny house when using propane appliances.
  • Ventilation: Ensure proper ventilation, especially with ventless heaters.
  • Clearances: Maintain proper clearances around the heater according to manufacturer specifications.
  • Regular Maintenance: Have your heater and propane system inspected annually by a qualified technician.
  • Propane Storage: Store propane tanks outside the living space in a secure, ventilated area.

Cost Analysis

Propane heating for tiny houses is relatively economical:

  • Initial Investment: $500-$1,500 for the heater and installation
  • Fuel Costs: According to sources, expect to spend around $100 per year for heating and cooking with propane in a typical tiny house
  • Maintenance: Annual inspection costs of $50-$100

These costs make propane heating one of the more affordable options for tiny house dwellers, especially those living off-grid.

Alternative Heating Options

While propane heaters are popular, they’re not the only option:

  • Mini-Split Heat Pumps: Efficient electric option that provides both heating and cooling
  • Wood Stoves: Traditional heating method with special small versions designed for tiny houses
  • Pellet Stoves: Wall-mounted versions are available specifically for small spaces
  • Electric Heaters: Simple solution if you have reliable grid connection or robust solar setup

Conclusion

Propane heaters offer an excellent heating solution for tiny houses due to their efficiency, reliability, and relatively low operating costs. Whether you choose a direct vent wall heater like the Williams model or a marine-style option like the Dickinson, proper sizing, installation, and safety precautions are essential.

For tiny house dwellers, especially those living off-grid or in mobile situations, propane heaters provide dependable warmth without requiring electricity. With annual fuel costs around $100 for both heating and cooking, they represent an economical choice that helps make tiny living comfortable year-round.

Before making your final decision, consider your specific needs, climate, tiny house design, and whether you’ll be on or off-grid to determine the best heating solution for your unique situation.
