Common questions
What happens to my oil tank?
Mass Save requires the old fuel source to be removed or disconnected and documented on the invoice when a partial-home rebate fully displaces a heating zone. For a whole-home rebate the heat pump is the sole heating and cooling source. Ask us who handles the tank.
Does my panel need to change?
Sometimes. An electrician checks the service size and panel space. See the panel upgrade page, and send a photo of your panel with the request.
Do I keep my boiler as backup?
You can, as a partial-home project. The rebate is smaller, and Mass Save requires an integrated control on zones where oil, propane or gas stay in use.
Have an oil boiler?
Send a photo of the boiler and one of your panel. We look at them and get back to you.
