I recently installed an Emporia Vue with monitoring for the individual circuit my water heater is on. It captured the very significant difference in energy usage from replacing resistive heat with heat pump.
In my area (in the SF Bay Area) there’s barely any upfront cost, as there’s something like $4k in local and state rebates plus the 30% federal tax credit.
