In one room of our house I have an old style ho****er baseboard heater that
is encased in a heavy gauge metal cabinet that measures 6 feet wide, 30
inches high, and 6 inches deep. There are slotted cuts in the face of the
cabinet near the top to let the heated air out. There is about a 4" gap
under the cabinet to let cold air in at floor level in the front of the
cabinet. The cabinet covers a finned baseboard element about 6 inches deep
2 inches thick and 4 inches above the floor. I want to build a new cabinet
that is the 6 foot width but only about 1 foot high. Would I be losing a
tremendous amount of heating capacity. Thanks for any input.
