Baseboard Heaters Under Cab
I did it! In the section of toe-kick where the heater resides, I made deeper to accomadate the heater depth and the overall height was increased as well (7" as I recall).
I placed a peice of sheet metal, the length of the heater, behind the heater brackets as I fastened them to the toe-kick backer and it extends up over the heater curling toward the front and stops short of the cabinet face (under the deck). During cold months when the heater is active, the cabinet doors above the heater feel only slightly warm to touch, yet the room is filled with heat as expected.
Looking back (to be extra safe), I should have inserted a layer of foil insullation (the type used to wrap ducts) behind the sheet metal to further insulate the cabinet.
Hope this helps ya,
