Hi!
I have no idea which size heat tape to get for 34qt sterlite tub. It is not a rack system but for one tub. It measures about 26 inch long and 16 inch wide. I am deciding between 11 or 6 heat tape. 11inch heat tape seems to cover about 40% of the tub which seems too much. But 6 inch covers 25% which seems good but I feel like I would need some extra heat help during winter so I was leaning toward 11inch. Any advice or suggestion?
