Consider adding thermal curtains over windows and door sweeps to eliminate drafts, which can improve your heater’s efficiency by up to 25%.
Size and BTU Output
Selecting the right-sized heater is crucial for tiny homes. Calculate approximately 3,000 BTUs for most tiny spaces—oversized units waste energy while undersized ones work inefficiently. Use a BTU calculator that factors in your specific square footage, ceiling height, and climate zone for precise sizing that maximizes efficiency without overworking your electrical system.
Placement
Strategic heater placement creates optimal warmth distribution. Install wall-mounted units at least 3 feet from furniture and 12 inches from the ceiling. Position heaters on interior walls rather than exterior ones when possible, and place them near areas where cold air enters (like windows or doors) to intercept drafts before they spread throughout your space.
Optimal Placement in Tiny Home Layouts
Main living areas benefit from wall-mounted heaters installed at knee height for efficient convection flow. Use under-cabinet heaters in kitchens to save valuable counter space. For lofted tiny homes, remember that heat rises—position your primary heater on the main floor with a small secondary unit in the loft if needed.
Ventilation Considerations for Safety
Install carbon monoxide detectors near any combustion-based heater and test them monthly. Ensure proper clearance around all heating units—at least 3 feet from flammable materials. For propane heaters, implement a cross-ventilation system with vents at opposite ends of your tiny home to prevent dangerous gas buildup while maintaining indoor temperature.
Maintaining Your Space Heater for Long-Term Efficiency
Proper maintenance of your space heater ensures optimal performance, extends its lifespan, and maximizes energy efficiency in your tiny home. Regular upkeep not only saves you money but also keeps your heating system operating safely.
