This Gas Emerging Technology (GET) study project is proposed to monitor and analyze the potential gas energy savings from replacing non-controlled domestic hot water (DHW) circulator pumps with smart circulator pumps. Smart circulator pumps use either a timer, aquastat, timer + aquastat, or an...

This project is proposed to perform energy modeling and analysis of dual fuel heating systems in the single-family homes of California. The study will model different dual fuel heating scenarios using DEER EnergyPlus single family prototype models built around several parameters such as switchover...

This project will be an updated and broad approach to look at specific measures for enhancing the energy efficiency (EE) of boilers in CA IOU territory. Rather than focusing on boiler retrofits, which are already part of the IOU portfolio, this study will investigate the potential for add on and...

This project is phase 1 of a multi-phase pilot project for gas-fired heat pump water heaters & combination systems. This phase 1 project will do all the groundwork for the future phase 2 and 3 projects to install gas-fired water heating/combination equipment at various sites around California. ...

The project will research emerging Ultra-low NOx (ULN) Burner technologies to provide actionable recommendations of technologies and gaps for further study by the GET program. This project will research and evaluate cost-effective, efficient, and ultra-low emission burner technologies including...

Water heating represents significant energy use in residential applications. Therefore, energy efficient water heating is an essential component to achieve California’s saving goals. Although gas-fired heat pump water heaters (gHPWH) have been around for over three decades, this technology has only...

This Emerging Technology (ET) study project is proposed to research emerging gas-fired water heating technologies in order to provide actionable recommendations of technologies and gaps for further study by the Statewide Gas Emerging Technologies (GET) program. This project will cover both...

This Emerging Technology (ET) study project is proposed to analyze & research natural gas water heating technology adoption trends in existing California Investor-owned utilities (IOUs) offered Energy Efficiency (EE) incentive programs, perform market research to understand technology adoption...

This project is in phase 2F (field study phase) of a multi-phase field study pilot project for gas-fired heat pump water heaters & combination systems. Phase 1 of this pilot is already underway to address initial planning and data gathering necessary for phase 2F to launch. Phase 2F plans to have...

This Emerging Technology (ET) study project is proposed to research & analyze energy efficient (EE) technology adoption trends, barriers to EE equipment adoption, and gain feedback on installed EE equipment in the commercial food service (CFS) market to provide actionable recommendations to improve...
