Kinda scary looking, on bedrock, bit of a river flowing when it's wet out. Old oil furnace, one of the things I like least about this place. Medium term, it's got to go, possibly replaced with either a forced air electric furnace, or maybe even converted to electric water circulated.
Unsure, definitely open to green options.
Also thinking of doing solar hot water, so possibly we could combine that into home heating as well?
