Shared steam boiler cleared so each unit of a duplex gets its own furnace
Example project
- Home
- 1910s up-and-down duplex in Minneapolis, both units rented, with one steam boiler in the basement
- Original request
- Replace the shared boiler with a separate furnace for each unit
- Testing
- Samples by an MDH-certified inspector of the boiler jacket, the steam pipe wrap, the elbow fittings and the newer water heater pipe
- Found
- Asbestos in the boiler jacket and in the wrap and fittings on about 100 ft of steam pipe
- Clear
- No asbestos in the insulation on the newer water heater lines
- Work
- Basement sealed under negative air, the jacket and wrap kept wet and removed in sections
- Timeline
- Five-day notice, then three working days
- Cost
- $7,500
In this example, the owner of a 1910s duplex in Minneapolis rents both floors and heats them with one old steam boiler. The plan is a furnace for each unit, so each tenant controls their own heat, and the boiler and most of the steam pipe have to go.
