Existing Conditions
Hot water wall-fin convectors, mounted under windows, deliver heat to the suites. Much of the heat is radiated against the outside wall, rather than out into the occupied space. The surface of the wall absorbs most of that radiant heat and then conducts it to adjacent wall areas and out through the insulation and building façade. The colder it is outside, the more heat is conducted out through the walls.
<This is an older building, with very little wall insulation, making this heat loss even more significant than it would be in a new well-insulated building.>
Retrofit Conditions
Reflective panels can be installed behind wallfin radiators to bounce radiant heat back against the metal convector cover. Less heat is absorbed by the outside wall to be conducted outside.
While the convector covers are off, the Contractor will clean the convector fins of any dust accumulation, and will use expanding foam to seal any air leaks between the wall and floor slab.
Once the convector covers are replaced, the installation is invisible.
Installation of reflective panels will increase the effective capacity of the convectors, and so should be accompanied by adjustment to heating plant controls.
