Triple-decker boilers
Each unit may have its own boiler or share one. Narrow basements with stone foundations make access and venting tricky.
Chimney liners
Older chimneys may need liners when boilers are replaced, especially after oil-to-gas conversions.
Rental housing
Many Somerville residents rent. Report heat problems to the owner in writing.

- Boiler starts and shuts off, or shows a lockout light
