Buying Guide For Tiny House Mini Splits
BTU Capacity is crucial for tiny houses. Calculate 20 BTUs per square foot for standard insulation, or 15 BTUs for well-insulated spaces. Most tiny houses need 9,000-12,000 BTU systems, with 9,000 BTU suitable for 400-450 square feet and 12,000 BTU for 600-750 square feet.
Energy Efficiency Ratings directly impact operational costs. Look for SEER2 ratings of 19 or higher and HSPF2 ratings above 8.0 for heating. Inverter technology provides variable speed operation, reducing energy consumption compared to fixed-speed systems.
Installation Requirements vary by system complexity. Consider electrical requirements (most tiny house systems use 115V), mounting space for indoor and outdoor units, and refrigerant line routing. Many systems include installation kits, but professional installation may be required for electrical connections.
Smart Features enhance convenience in tiny spaces. WiFi connectivity, smartphone apps, and voice control through Alexa or Google Assistant allow remote operation. Timer functions, sleep modes, and programmable schedules optimize energy usage and comfort.
Noise Levels matter significantly in small spaces. Look for systems operating below 45dB, with the quietest models running below 40dB. Indoor unit placement away from sleeping areas and vibration-dampening features reduce noise transmission.
Heating Performance is essential for year-round tiny house living. Heat pumps should operate effectively to at least 5°F (-15°C) for most climates. Consider backup heating options for extremely cold regions where heat pump efficiency decreases significantly.
Maintenance Accessibility affects long-term operation. Choose systems with self-cleaning functions, accessible filters, and clear diagnostic features. Regular filter cleaning and annual professional service ensure optimal performance and longevity.
