2 ply liners suck and filling around it is not a guarantee that the liner will not be touching the bricks unless spacers are used all the way down. It would be much better to install a pre-insulated liner or just insulate the outside of the liner with the wrap.
I don't understand why oval vs round would change anything as far as the crock goes. Either the crock needs work or it doesn't the shape of the liner doesn't matter.

Double wall liners suck.

You don't have enough room for proper pour in insulation in your chimney with a round liner.

So I need to learn the difference between them. So what do I want? Most people call the double wall liner "stainless".

All metal liners are stainless. There are basically 4 types of ss liners. Regular corrugated light wall which is .005" or .006" thick.

2 ply smooth wall liner which is the same thickness but has an inner overlapping edge that is unsupported on the bottom forming a smooth interior.

Mid weight and heavy wall which are .010" or .015" respectively. They are an interlocking coil which is much more durable and smooth wall.

Rigid pipe which is just sections of pile joined together to form a full liner.

2 ply is the least durable. Rigid and heavy flex are about the same for most durable

Thank you, I will refer to this when trying to figure it out.
 
Do you happen to know if any of the Regency stoves are larger than that? Do you like them over the Princess? I cannot remember why but when I was doing my research I was gravitating toward the Ashford 30.2 over the Princess 32.
What did you go with? I’m struggling to decide between the tried and true princess design versus the aesthetic of the Ashford
