Anyone thinking about doing any upgrades or new systems in Mass should do some research on upcoming incentives. I listended to a webinar yesterday from the Mass DOER and they have lots of money to spend on all sorts of renewable options, they listed upcoming programs for pellet boilers, wood stove upgrades, OWB replacements, solar hot water and electirc, geothermal and probably a few others. They didnt discuss the value of the rebates but many of the options have one hundred to 1 millions dollars int he kitty. A lot of the programs are not in place but will be phased in. Most have limited numbers of systems so its first come first served. Might be worth doing some reasearch at Mass Clean Enery Center website and see if there are any incentives now or upcoming that might fit a project you already planned. I dont live in Mass, so I will let those who do figure out the details.
