Hi I'm new to this forum. I'm interested if there are any owners of Hwam wood stoves out there? My interest is in finding information on fire brick.

Hwam stoves are made in Denmark. I'm guessing they were around the USA for about 10 years. My wife and myself purchased a Classic #7 about five years ago before they decided to pull their entire line out of the USA. At this time, I'm in need of new firework which is going to cost a fortune to import. From what research I have done already, it appears a standard fire brick for a wood stove is about 9"x 4.5"x1.25". Is it possible to purchase fire brick larger than this but the same thickness? As a contractor I'm thinking I can do some fabrication to make them work in my stove. Thank you for your time.
They are high quality and efficiency wood stove makers and regular contenders in the Green Heat wood stove decathalons.
Which model Hwam is this for? What is the size of the firebrick? I have seen 12" x 4.5" x 1.25" in some US or Canadian stoves, though I can't remember which one.

I have the Classic 7 with the bake oven on top. Since they have pulled out of the US, I have to buy parts from a shop in England. They just gave me a quote with shipping for $550. Seems a little excessive. When we stop burning here in Rhode Island, I will do a good job of cleaning out the stove and be able to get some relatively accurate measurements on the existing fire brick. Right now I'm just trying to locate some brick that might be a little larger in size to work with.

You need to know the size of your fire brick. I would think you could cut your own especially since you are a contractor. Firebrick comes in different duty statuses and thicknesses. In wood stoves I think lower or medium duty status bricks are used - usually because these bricks are cheaper than high or super duty status bricks. You could manipulate how your stove burns a little bit by altering the fire brick.
The higher the duty status the heavier and tougher the brick. Lower and medium duty bricks have more sand in them and slow heat transfer down a little bit (more internal voids so higher insulating), and they expand/contract better (some say). Super duty firebrick are used to melt down weapons in kilns - they get these brick up to a high Temp and leave them there. And I'm not including those light insulating bricks - these are a whole different brick, but they tend to be called fire brick too.

Thank you everyone for getting back to me. I'm still doing some research on fire brick. My my thought is, I can use the existing fire brick which is not completely destroyed as a pattern for the new brick that I need.
