Buying Guide For Mini Split Heater Only Units
Selecting the right mini split heater unit involves considering several key factors to ensure efficient and comfortable heating performance in your space.
Heating Capacity and Room Size
Match the BTU capacity of the mini split heater with the square footage of the room. Units rated around 9000 to 12000 BTU typically heat spaces between 400 to 750 square feet. Oversized units can waste energy while undersized units struggle to maintain warmth.
Energy Efficiency Ratings
Look for SEER2 and HSPF2 ratings which indicate cooling and heating efficiency. Higher ratings mean lower operational costs. Inverter technology improves efficiency by adjusting compressor speed rather than cycling on/off frequently.
Heat Pump vs Electric Resistance
Most mini splits use heat pump technology, which moves heat rather than generating it, resulting in better energy efficiency especially in moderate climates. Resistive heaters consume more power and are less common in mini splits.
Installation and Features
Consider units with included installation kits for ease of setup. Smart features like WiFi control, timers, multiple operating modes, and quiet operation add convenience and flexibility to day-to-day use.
Refrigerant Type
Eco-friendly refrigerants like R32 are increasingly used and reduce environmental impact compared to older refrigerants. Ensure the unit complies with local regulations and availability of refrigerant refills.
By considering these factors, you can find a mini split heater only system that is energy-efficient, easy to install, and capable of providing comfortable heating tailored to your needs.
