Ductless minisplits differ from conventional air-source heat pumps in several ways: first of all, they are extremely efficient, in part because of the use of inverter-driven compressors. Secondly, many of these units can operate efficiently at very low outdoor temperatures.
Since a compact home with high levels of insulation can be heated and cooled with just one or two ductless minsplit units, this type of heating system is very affordable.
The new article answers dozens of questions, including:
- What’s the difference between a ductless minisplit system and a conventional air-source heat pump system?
- Can the outdoor unit of a ductless minisplit system handle several indoor units?
- Why are ductless minisplit systems particularly appropriate for renovation work?
- Why are designers of energy-efficient homes showing an increased interest in ductless minisplit systems?
