I have fin tube radiation in a building, the problem is they built a cabinets around the radiators with a grill at the bottom and grill at the top both on the front. Granite tops, so I can't put a grill in the Granite. There's not enough convection so the rooms are freezing, inside the cabinet is roasting hot. Looking for a small blower assembly to put behind the grills which are 3 to 6 feet long and 6 inches high. BTW we talked about having new fronts made and putting muffin fans behind Square grills, it got shot down. 120 VAC is available for power, PE Switch will control the fans.
