Optimized Installations of Air Source Heat Pumps for Single Family Homes

Date: Wednesday, December 13, 2023, 11:00 a.m.?12:00 p.m. CT

Cold climate air source heat pumps (ASHPs) are the technology expected to provide an estimated 25% of total residential electrical savings in the state in the coming decade (MN Energy Efficiency Potential Study [ [link removed] ], 2018). This will be an essential component in meeting Minnesota?s energy conservation goals. As interest in ASHPs increases statewide as well as nationally by stakeholders, installations continue to rise, and more applications are developed, the ability to estimate savings will continue to be important for homeowners, contractors, and programs. Although installations are increasing, barriers remain to meet our local and national goals. In response, Center for Energy and Environment will share research results in this webinar, such as:


* Installation and evaluation of a sample of cold climate ASHP systems in Minnesota homes, including: the trade-offs of different ASHP applications and approaches, installation best practices, the importance and impact of good controls, and interactions with existing and supplemental heating sources.
* Detailed performance data and impact of installation and control decisions on final results, as evaluated over a at least one full heating season.
* Analysis of the performance of ductless multi-head heat pump applications, the first analysis done in cold climates.
* Implications on savings calculations important to the state?s Technical Reference Manual.

Air-to-Water Heat Pumps: A Cold Climate Solution for High-Efficiency Cooling, Space Heating, and Water Heating

Date: Tuesday, December 19, 2023, 11:00 a.m.?12:00 p.m. CT

Air-to-water heat pump (AWHP) systems are a flexible type of air source heat pump that could extend heat pump savings to more customers and integrate hot water loads. However, with this flexibility comes complexity that may hinder adoption of this new technology. In response, Center for Energy and Environment will share research results in this webinar to fill knowledge gaps and provide context to AWHP systems for Minnesota consumers. System configurations for serving heating, cooling, and hot water loads in cold climate single-family homes will be clarified based on recent market research. The strengths and weaknesses of commercially available AWHPs will be uncovered further by examining detailed field monitoring results of four AWHP retrofits in Minnesota. These field results provide real-world data on the cost-effectiveness and energy saving capabilities of AWHPs in cold climates.

Join us on December 13 [ [link removed] ] to hear key findings on ?Optimized Installations of Air Source Heat Pumps for Single Family Homes?, and/or join us on December 19 [ [link removed] ] to hear key findings on ?Air-to-Water Heat Pumps: A Cold Climate Solution for High-Efficiency Cooling, Space Heating, and Water Heating? that can be leveraged to target ECO offerings and tailor interventions to most effectively impact the market.

The purpose of the Conservation Applied Research and Development (CARD) Grant Program is to identify new technologies, strategies and program approaches that utilities can implement to help achieve the annual state energy-conservation goal as established by the Next Generation Energy Act of 2007 and modernized by the Energy Conservation and Optimization Act passed in 2021.
