Heating Thermostat Control for 5 Family Building

[Ariel Cohen]

I closed on a 5 family brownstone in Brooklyn last week. The building was occupied by the owner who lived in one of the units and had the thermostat that controlled the heat for the entire building in her unit.

The heat for the building is produced by a single gas fired steam boiler which was installed last year when the old oil boiler was replaced.

What is the best option for controlling the heat for the property? All of the units will be occupied by tenants.
