This is a basement stove of a house built in 1955. It is an Englander. Can anyone comment about how well this stove works, and further- I'd like to know what you think of the hearth (why are there bricks scattered about) and the pipe into the wall (are those creosote stains, and does that mean there is a leak that needs to be sealed? Why is there a second pipe on top, and what are those four dial-like things?
