Switch It Up! How to Determine Appropriate Switchover Temperatures for Dual Fuel ASHPs

Good news, the client wants to buy the dual fuel heat pump that you've bid! Now comes the fun part, how do we size, install, and set the controls for the optimal switchover temperature? Also, what the heck is a switchover temperature? In this fun and geeky session, Dan, Jordyn, and Ranal will discuss the difference between different target switchovers, or balance points, based on thermal/capacity limitations, economic goals, environmental impacts, and optimized comfort. This session will define these switchover temperatures, explore their driving forces, and discuss the recommended practices for finding and setting them. For the customers most focused on minimizing operational costs, finding and setting the best economic balance point will be critical and probably shouldn't be left to rules of thumb. This is a great opportunity to discuss what approaches make the most sense for you as a contractor or as a program to get this right. We'll include the recommended practices, tools to use, communication strategies for homeowners, and adding to your service/maintenance contracts ways to fine tune this experience for your consumers.
