Water, Energy and Time Efficient Hot Water Systems for New Homes – Rebuilding for Comfort, Efficiency, and Affordability
June 1, 2018 @ 1:00 pm - 5:00 pm
In this fifth session, Gary Klein will discuss hot water systems. The session is intended for all audiences: home owners, plumbing construction veterans, and all other building professionals.
Hot water systems include the heater, distribution piping, plumbing fixtures and appliances, and the capture of waste heat that would otherwise run down the drain. Water heating has changed considerably in the past twenty years with increased adoption of on-demand and heat pump technologies. Distribution systems have also been rethought. Occupant expectations have evolved as well. Given these numerous changes, many building professionals design and build hot water systems based on information that is years out of date. Using current information, how can we reduce energy used for delivery and heating of water while also managing the volume of water used?
Gary Klein will explore the following questions that affect the performance of a hot water system.
What are key hot water efficiency considerations to keep in mind when designing a building?
What is the most energy, water, and time efficient way to install a hot water distribution system for a given floor plan?
What criteria should guide selection of a hot water system?
What are criteria by which to select hot water system components?
When should you install water heaters in multiple locations?
When is it appropriate to use drain water heat recovery systems?
How can these many considerations be integrated into a good, efficient hot water system that works with the building design?
This training was organized by PG&E and is offered in collaboration with County of Sonoma Energy and Sustainability Division, County of Marin Community Development Agency, and Sonoma Clean Power. Lunch will be provided for class participants.
