Hi Firebug we missed you. Love those stoves.
I am starting to put together a Dahlen original pre AGA. I believe it to be the oldest AGA in existence.This stove which was made in Sweden and is a wood burner. It weighs over a ton (my one ton forklift had it's rear wheels off the ground) and thanks to your post it just occurred to me.
Of course, it can be an intermittent heater and supplier of DHW as the mass will take time to cool down. The water is warmed in a 400 pound copper (
) jug as it is a batch water heater. I am wracking my brain to see how it can burn anthracite but that is just not going to happen as it has no ash tray to speak of. I am going to clean it off today and post pics. Massivity works too.
