List the various situations which would justify the much greater cost of setting up a central boiler system compared to a localized forced air heating system
What will be an ideal response?
The central system could burn cheaper fuel such as heavier grades of oil,
wood, or coal. It could provide the hot water needed for a floor or bench heat
distribution system. It could provide steam for a greenhouse range where steam
pasteurization is the desired means of cleaning the root substrate. For a very large
firm the upkeep of a central system could be cheaper than numerous localized
heaters.
