This guide from NEEP (Northeast Energy Efficiency Partners) has 2 main sections.
Part 1 describes the basics of what a heat pump is, how it works, what types are available, and how to think about choosing one for your home.
Part 2 helps organize the process and offers a checklist of questions to ask potential installers, what to look for during the design and installation process, and how it fits into your particular needs.
Air-source heat pumps (ASHPs) are successfully being used in cold climates, but system sizing and selection practices have not always kept up. Poor sizing and system selection can negatively impact performance, comfort, and energy efficiency. This guide will assist installers when sizing and selecting ASHPs for cold climate applications.
