Leda Coal Heater

Is anyone familiar with older LEDA coal stoves? (cast innards shrouded by a ceramic coated steel cabinet). I bought one on CL for $75 in excellent condition. Attached to the back side of the loading door is a small ( 6x4x4) perhaps broken, cast or refractory cement hollow box that, when the door is closed, extends into the upper part of the firebox. Does anyone know its purpose? Niether Google or YouTube has info.

looks like a secondary air pre-heat chamber to me.

Secondary pre heat chamber-never heard of one. How would it work? There is no air inlet to that "box", in fact there is no secondary control on this heater- just a thermostatically controlled primary inlet sitting low on the side of the cabinet. There seems to be a hole in the crumbly cement now -should there be?

my bad, I mistook the door handle for an intake spinner.

no clue now.

I believe it may just be a chunk of refractory to keep the door temperature down low. It appears the hollow as an insulating factor. To make a repair, get some heavy gauge screen and shape it to hold itself in the hole and apply refractory cement. Let it cure as instructed and then very long, small fire to finish it off . Probably wood if you can use it. A hot fire may be too much for a repair patch.

Boy, we think alike!! I came up with the same thought. It transfers tempered heat to the door and to repair stuff it with wire fabric and slap cement into it.

Make sure you don't fill the hole up, just cover the opening. You could go a little thicker, make sure you get the new to overlap both in and outside. The overlap can get thicker as required for a strong repair. Scuff the old up with some coarse sandpaper for a good stick. Repairs like this are not a permenant fix but 5-10 years may be?

X3 on the insulated door. looks like a good deal on your stove. Curious to hear about its performance.

I'm beginning to think that the box on the back side of the door originally was completely closed( with no hole). If the box was completely sealed with cement the heated air inside would heat act as insulation to the door. If there was a hole, very hot gas/air would be applied directly to the door- no insulating effect. What d'ya think?

I believe your thought is correct.
