This research project was performed to support the development and implementation of California’s Title 24, Part 6 Building Energy Efficiency Standards (Title 24) by better understanding the impact of installation location and ventilation on consumer integrated heat pump water heaters (HPWH)...

120V HPWH products are completing lab (UL) testing at this time and are expected to be available for field testing in Q1 2021. A field study of 8 units in SCE service area using 120V products will enhance the understanding of how the products perform and how they can be deployed. This field study...

Develop a tool that assesses energy, emissions, and operating cost for different types of domestic water heating technologies. It will include analysis for the tool and will also assess water heater operation with and without rate responsive load shifting...

The purpose of the Midstream HPWH Market Study was to assess barriers to increasing adoption of connected HPWHs by conducting interviews across seven different types of supply chain stakeholders. The Project Team identified the greatest barriers per stakeholder group and developed implementation...

The main objective was to shift the energy use profile of water heaters on a daily basis from the 4 to 9 pm peak period to lower-cost hours thus, avoiding congestion on the grid and aligning with time of use (TOU) rates. The study assessed two different water heater technologies: smart control...

Codes and Standards will work with ENERGY STAR on two aspects: 1) update the test methods for “connected water heaters” and ENERGY STAR...

Domestic hot water system electrification is a high-potential decarbonization opportunity in multifamily buildings. Based on U.S. government data, this end use accounts for 28% of multifamily residential energy consumption in the United States (EIA, 2016). Centralized heat pump water heating...
