0% HEAT Loans still offered to MA residents
MA Homeowners - Per MASS Save website, their 0% HEAT Loan is still being offered. "The Mass Save HEAT Loan offers interest-free financing opportunities up to $25,000 for energy-efficient home upgrades like the installation of air source heat pumps (central or ductless mini-split), ground source heat pumps, heat pump water heaters , insulation, and more."
As someone who has taken advantage of this product, I'd highly recommend looking into this loan if you need to do specific energy improvements to your property. I doubt this will be offered much longer as rates continue to rise. This can also work with house hacks.
