Dismantling, rigging, piping and electrical modifications are needed. Re-use of the existing burner with a new boiler might save some costs. Zone control and piping insulation are being investigated as separate costs. Asbestos abatement is excluded.
Cost estimates have ranged from $30K to $45K. Comparisons are incomplete among the different contractors, but addressing the magnitude of costs for a replacement boiler must be a congregational decision in the coming months.
