I haven’t written about this before, but we had a new heating and cooling system installed in December. Through the City of Somerville’s Heat Smart Cool Smart program, we installed an air source heat pump system in our house. To be sure, our existing heating system was working fine and we already had central air conditioning. But I had a strong preference to electrify my heating, in other words, to stop burning home heating oil. And there are additional benefits, notably that we have five separate zones, instead of just one thermostat for our whole house.
Air source heat pumps aren’t that easy to understand, unfortunately. Today, I presented the program and the technology to Fossil Free Somerville, with a member of the City’s housing office. Added bonus, of course, is that I got to sit in on their meeting and learn more about their divestment campaign in particular.
