The Heat Pump Technologies fact sheet provides an overview of modern heat pump systems used in existing buildings, including air‑source, water‑source, and variable refrigerant flow (VRF) technologies. It explains how heat pumps deliver high‑efficiency space heating, cooling, and domestic hot water while reducing greenhouse gas emissions compared to conventional systems. The fact sheet also highlights key performance metrics, operational considerations, and recommissioning opportunities to help building owners and operators maximize efficiency and reliability when deploying or optimizing heat pump systems.
The fact sheet was prepared by Prism Engineering on behalf of Natural Resources Canada (NRCan).
