2) Some jurisdictions treat hot water systems more leniently than steam systems. For example, the aforementioned system does not require continuous monitoring by a stationary engineer, and the municipal approvals for 'hot water' were easier than they would have been for steam.
3) It is easier at the loads to use water/water heat exchangers rather than steam/water, if the loads include domestic hot water and hot water heating.
4) Sometimes, there is more potential useful waste heat available to a system that only requires 100-125°C of supply temperature than to a system that is looking for steam as source.
