B4 2021 Session 3: Air-to-water heat pumps and hydronic systems
May 26, 2021
Technical Session: 12:30–2 p.m. Central
As the energy market shifts toward beneficial electrification, we’ll continue to see an increase in the use of heat pumps as heat sources for many building systems, and hydronic systems are no different. One of the most promising options for hydronic systems is the air-to-water heat pump, which extracts heat from outdoor air—even at sub-zero temperatures—and delivers it through a water-based distribution system. This combination can provide superior comfort while meeting energy efficiency goals, making it a great choice to meet the market demand for decarbonization.
In this session, hydronics expert John Siegenthaler describes the breadth of currently available air-to-water heat pumps, including their performance characteristics. He then shows how to combine these heat pumps in both new and retrofit situations, sharing practical do’s and don’ts as well as several templates that can serve as starting points for optimal system design.
Break: 2–2:10 p.m. Central
Enjoy a performance from Slipstream's house band, Turbulence.
Fireside Chat: 2:10–3 p.m. Central
We continue the overview of air-to-water heat pumps with an interactive discussion of how to apply these technologies to meet our energy efficiency goals.
As a result of this webinar, you will be able to:
- List the benefits of air-to-water heat pumps
- Describe the importance of matching air-to-water heat pumps with low-temperature distribution systems
- Identify potential design or installation mistakes that could compromise system performance
- Select an appropriate system template depending on the loads the heat pump will service
