I have three CB-70 racks from Rich. Love 'em.
If your room is on the cool side, you should have some supplemental heat, above and beyond the heat tape - but that's pretty normal. The instruction sheet will tell you not to set the rack on carpeting - listen to it.
Among the best features about RB racks is the customer service you'll get from Rich - you won't be unhappy with this choice!
