We built this rack but added heavy duty castors to the bottom. The weight is definitely a downside. Other than that it hasn't warped at all (it’s about a year old). I wouldn't worry about heat damage either as BPs don't need temps over 90*. Plus melamine is very easy to clean compared to wood. Also, each shelf has a separate strip of heat tape so if the heat tape fails I would only need to replace that one small section. As opposed to my Animal Plastics racks that have one continuous piece of heat tape. I really love this rack.
