TRAINING FULL...SECOND TRAINING OFFERED IN 2023..Heat Pump Series: Understanding Common HVAC System Types and their Heat Pump Upgrade Options
Tuesday, October 4, 2022 - 8:30am to 5:00pm
Training Overview:

This one-day course is intended to help attendees become familiar with several different types of HVAC systems commonly used in commercial buildings. We describe how each system works, how to identify them, and what types of buildings it is found in. Then for each system type, we will discuss various ways that it can be upgraded to (or combined with) heat pump technology to improve system efficiency and help with the electrification movement.

Event Benefits:

In-person training focused for groups to ask all questions in relation to Heat Pumps and all applications in your field and work site.

Who Should Attend:

All vendors, and End-Users associated with EVERSOURCE and NGRID.
