The objective of this project is to evaluate the performance in the laboratory of two small wall-mounted Heat Pump Water Heaters from Europe and their ability to provide hot water in a more efficient manner and with lower total emissions. The HPWHs are commercially available in Europe,...

This project created algorithms predicting the performance of drain water heat recovery devices as a function of their installed angle. The algorithms use the same process as previous Pacific Gas and Electric (PG&E) drain water heat recovery projects1. Four representative DWHR devices, two...

The overall goal of this project is to promote low GWP water heating technologies for central system applications typically found in multifamily and commercial buildings, increasing load shifting capabilities using central water heating systems, and developing best practice guides that simplify the...

This study evaluated the performance of unitary heat pump water heaters (HPWHs) operating in a shared configuration (each unit served four apartments) in an affordable all-electric multi-family project located in Davis, CA. The shared configuration allowed the HPWHs to be placed in close proximity...

A compact, Bluetooth enabled, inline digital natural gas flow meter has entered the market, with two models anticipated for 2018 market entry (Table 1.)  Both models can be installed in tight spaces and do not require venting.  The submeters are represented as being pressure independent...

This project evaluates whether the introduction of high-resolution AMI-dependent household water information to single-family residential consumers results in water, electricity, or gas savings through direct or behavioral changes at the household. This was accomplished by designing and performing...
