Gas boiler decommissioning

Gas decommissioning is the most straightforward of the three decommissioning types. The homeowner has two choices for what happens to their existing gas boiler.

Option A — Leave the shell, remove components

Section titled “Option A — Leave the shell, remove components”

The boiler shell stays in place. All heating components are removed so the unit no longer functions. This is the default and cheapest path.

The entire boiler is removed from the premises. This requires adding a boiler removal adder to the order.

  • All standard decommissioning permits: electrical + mechanical + plumbing (see Permits)
  • The boiler removal adder if going with Option B
  • Equipment to cover full-home BTU (heat pump central air defaults to 5 tons on decommissioning — see Central air)

“Can we just leave the boiler completely in place?” No. The heating components must be removed at minimum. Option A leaves the shell; it does not leave a working boiler.

“Can we keep the boiler as backup?” No. Decommissioning means the gas system is retired as a heat source. If the homeowner wants to keep gas, that’s a non-decommissioning job or a hybrid setup.

Forgetting the boiler-removal adder when the homeowner wants the shell gone. Catch this at the sales appointment so it doesn’t surface as a change order on install day.
