Note that's for the whole home $10K rebate only. For the per-ton rebate, you can leave the existing fossil fueled appliance installed and connected. (It's also new for 2024; the 2023 rules allowed you to leave the appliance in to be used for supplemental heat during extreme cold or during an equipment outage. https://www.masssave.com/-/media/Files/PDFs/Save/Residential... )
Yup, me too. And with my Nest thermostat, I can manually configure the crossover point. I did so at the economic balance point (where the heat pump is cheaper than my gas furnace).
Is there any capability in having a "smart" economic balance point? IE: Accounts for time of day/market pricing of kwh? I guess there needs to be occasional reprogramming of gas prices?
No, unfortunately. But my gas/electricity is fixed price, so it doesn’t matter. I’m sure this will be coming as heat pumps get more common. It’s a pretty easy calculation to do.
