In buildings where a landlord controls the heat, ask the landlord to adjust controls. Do not tamper with controls in any managed building. Do not plug or adjust air vents in any building unless that is your job. Do not directly adjust a furnace. Remove portable space heaters from heated space.
Space heaters confuse a building's heating controls, causing other areas to lose heating.
More space heaters are then requested. The result can consume energy and cost for no net gain. A portable space heater is defined as having a maximum wattage of 250 watts or more. It usually has a fan or a reflector and glowing element. Agencies may provide foot warmers where necessary.
