Does anyone know the measurements on the T1/A3 boiler (ie diameter and length)?

In particular the melamine and the silicone foam both seem like appealing options, but the silicone is pricy and only 2 feet by 2 feet so if it is not big enough then the price skyrockets even more.

Second any further impressions on if there is any health risk in the melamine as an option? I think since it doesn't contact the water ever it would probably not have any risks, but there if there is any risk I'd rather pay extra and be safe.
