Pacific Gas & Electric

As our electricity supply becomes cleaner, due to an increased use of renewables for generation and a growing number of local ordinances prohibiting gas installs in new homes, electricity becomes an attractive fuel source to designers and builders interested in reducing residential greenhouse gas emissions and creating zero carbon homes. Dan Perunko of Balance Point Home Performance will present on efficiency gains, and overcoming common installation pitfalls from electric heat pump water heaters in new and existing buildings. Class discussion

Electrification is taking form in California. Gas water heaters are being phased out in the Bay Area by 2027 and over 70 municipalities have policies phasing out gas appliances. The massive transition from gas to electric will spark giant demand for all trades, including plumbers. In this session, Electrify My Home will introduce unique business opportunities for plumbers with a focus on heat pump water heaters, strategies for collaborating with other trades (e.g., electricians), and the importance of comprehensive electrification

Part 1 of 2  Part one of this series will provide an overview and introduction to mini split systems. Dan Perunko will also address the pros and cons as well as the relative efficiencies available for each system. In this session, we will also review how these smaller systems provide advantages for mechanical system design and layout. Agenda: Introduction and safety message Overview types of mini split systems Pros and cons of the different system types Load calcs, system layout

Waiting one to two minutes for hot water is excruciating. Yet we don't design our homes around this important goal of minimizing the time to get hot water at the tap. This intermediate level webinar covers the science of hot water distribution with guidelines to get Hot Water Time to Tap (TtT) down to 10 seconds, 20 seconds flat. This webinar will cover architectural compactness, pipe sizing, strategies for recirculation loop systems, and compare the energy efficiency of various systems.

Part two of this series will discuss installation best practices including line set construction and leak management as well as duct system design and installation. There is clear evidence that refrigerant release poses a significant hazard to our environment and Dan Perunko will review best practices to minimize this issue. Finally, this session will look at the new refrigerants options that are entering the market place. Agenda: Introduction and safety message Class poll: refrigerant types, global warming interactions, best practices

In this webinar, Judy Rachel will explain what a heating and cooling load calculation is and how it provides essential information for the successful implementation of electrification projects. Beyond providing the essential information for properly sizing a residence's HVAC system, the heating and cooling load calculation informs electrification project design and planning in significant ways. In addition, this presentation will explore the business case for this important planning step within the construction process. Accurately calculating the heating and cooling loads

This webinar equips participants with the knowledge to make smart, scenario specific choices when selecting heat pump water heaters (HPWHs). We'll begin with a brief overview of why HPWH deployment is a state priority, then explore the key factors that differentiate products, such as noise levels, ducting requirements, physical location constraints, electrical panel capacity, and more. The session concludes with an exercise exploring real world installation scenarios including garages, basements, indoor closets, outdoor closets, outdoor tankless replacements, and attics. Attendees

Part one of this series will start by covering best practices for line set testing, addressing refrigerant leaks and refrigerant line insulation. This session will focus on how efficient heat pump output relies on both refrigerant charge and total system airflow including: improving the airflow in existing systems, measuring and estimating airflow, and adjusting the airflow settings on various types of equipment. Agenda: Introductions and safety message Line set testing using high pressure nitrogen Line set testing and cleaning using

How do you know if a home is truly ready for electrification and what upgrades should come first? This fast paced, practical webinar teaches the core workflow used to assess residential properties for electrification upgrades like heat pumps, heat pump water heaters, induction cooking, EV chargers, and more. In 90 minutes, participants will learn how to evaluate a home’s electrification readiness by assessing electrical infrastructure, mechanical constraints, gas appliance inventory, safety issues, and overall installation feasibility. The session also covers

Part two of this series will prepare technicians, installers, raters and commissioning agents to address common service call complaints for heat pumps by demonstrating how to correctly collect and interpret power, static, temperature and airflow measurements. Dan Perunko will also cover the role of electric resistance heat in the operation of heat pumps and present on fan operation curves.
