Last month, we discussed how solid thermal energy storage, combined with an air-to-water heat pump and an electric boiler, provides a platform to leverage time-of-use electrical rates in ways that can benefit customers as well as the utility providing the electricity.
A problem is developing with the transition to electric heating: peak demand. Learn how air-to-water heat pumps tackle seasonal needs but struggle during extreme cold, leading to reliance on electric resistance heating.
On Demand This webinar explores how to size HPWH systems, discussing common mistakes, assumptions and limitations that frequently cause oversizing or under-sizing. We will also discuss the impact of varying hot water loads, demand responses, and ambient and groundwater temperatures on the sizing of HPWHs.
