Getting to Zero in NYS – Domestic Hot Water Design

ONLINE WEBINAR!
The building sector relies most heavily on fossil fuels (and consequently emit carbon) for space heating and domestic hot water production. That means that by 2050 these two processes need to be radically reformed. Powered by electricity rather than fossil fuel, we can transfer heat using air source heat pump (ASHP) to transform these systems in buildings small to large. While a cleaner grid would make ASHPs more sustainable, even with today’s grid (which is not zero carbon), ASHPs would have a lower climate penalty than any type of combustion heating.
Learning Objectives
- Distinguish between the different types of hot water heat pump technologies currently available on the US market.
- Identify two main points for selecting commercial-scale heat pump water heaters for cold climate use.
- Determine whether current NYC and NYS electricity grid mixes are favorable to electrification of DHW for carbon savings.
- Summarize the hurdles in pairing hot water heat pump technologies, mixing valves, and intermittent recirculation for a high-performance Energy Code-complaint installation.
- Explain why many large central Energy Code-designed gas-fired water heating plants are shown to performance below target efficiency levels.
