Park Tower’s “perimeter heating” is a form of radiant heating (no fan motors) that serves only the living rooms of our two-bedroom units, delivering heat via radiators underneath and running the full radius of the living room windows. Looked at from the outside, that would be around the curved corners of the building’s triangular shape.
Perimeter heating safeguards building integrity, provides warmth to areas closest to the large living room windows, and helps reduce condensation/frost in cold weather. It comes on automatically when the temperature dips to about 45 degrees. The amount of heat it emits varies directly with the outdoor temperatures as they reach and fall below 45 degrees. Residents may not notice at first, but the colder the temperature outside, the warmer the air should be radiating from those perimeter registers.
Don’t expect too much of this perimeter heating! It is and was always intended to be supplemental. The primary source of heat in all Park Tower living rooms is the convector assembly housed in the kitchen pantry. These convectors have motors that residents can set to low, medium, or high speeds, and they respond to thermostat settings. (Convectors heat our bed-rooms, too, and in the summers blow cool, conditioned air.)
So, we could not entirely offset the severity of the recent polar vortex, but perimeter heating is very effective in typical winter conditions.
