Central Heat Pump Water Heater – Advanced Design and Installation (Multifamily)
2024-05-23 09:00 - 12:00 UTC | Online
Overview
This training will take a deeper dive into CHPWH systems, design, sizing, and installation. Targeting contractors, MEPs and installers, the training will cover the content outlined below. The class will include hot water demand calculations to support system sizing and energy consumption modeling to support photovoltaic system sizing to offset usage. Learn about emerging technologies, new applications of existing technologies and controls to support all-electric water heating in multifamily buildings. Participants will work through an exercise using tools to size a system and consider equipment selection.
