Note to any non-professionals reading this: Do NOT try this yourself. What I'm about to describe is to be done by knowledgeable professionals ONLY.
This is one of those situations where the owners want to replace an old oil-fired boiler with a gas-fired one, but there is no gas service to the house (though it is in the street). Having to work with BGE, which seems to be on its own time zone, means we don't know when we can do the conversion. Then there's the asbestos abatement, which will of course be expensive. So, what to do? Right, get the existing boiler running as well as it can. It will probably have to run another year and maybe two.
The boiler is a very old National Heat Extractor, which also produces the house's domestic hot water. It has a built-in tankless coil, but someone disconnected that and put on a side-arm coil unit. The boiler water circulates thru the side-arm by gravity. The house was built around 1938, and we think the boiler is original to the house. The heat is forced hot-water with cast-iron radiators.
The burner went off on safety and the oil company said they needed to replace the pump (fuel unit?) again. The owners called us to ask about converting, and we went over to have a look. Here's what we found:
I won't mention the oil company's name, but it's the same one whose work we encountered here:https://forum.heatinghelp.com/discussion/132567/one-of-the-worst-maintained-oil-fired-boilers-weve-seen
