My only question is .. .would the 50-93 be a better unit for us..... We run the 30-95 on 11-12 on the damper on the back... stack temp about 200-300 .. and the stove temp around 400-450 deg I believe..
When the temp outside drops down to zero.. and the wind get really going ... our oil furnace will need to run a little bit... The room with the stove still stays around 70 .. (Floyd's quote)
Floyd, I have been burning my 30-95 for just under 1 year also. I heat my moderately well insulated house of 1200 sq.ft. with a flue temp of about 200* to 225* and a stove side temp of about 400* when it is arround 0* outside. My thermostat setting for the draft is at about 9 and barometric damper is set for .05 WC. This maintains a house temp of 70* to 72* in the living room where the Hitzer is. Temps in other 1st floor rooms probably abut 65* and upstairs about 55*. The lowest outside temps I have seen since using the Hitzer have been -6*. No problem heating at that temp., but I am wondering about the inevitable -20* (or lower) that we almost always get at some point.
To finaly answer your question; yes, I think based on your current output, you probably would have been better off with the 50-93 IF you need to heat 100% with coal. If you can live with a little fuel oil usage, It won't hurt to keep the furnace excersised and running once in a while. You want your furnace to remain functional as a backup should you be away from home too long to keep the coals burning anyway.
I suspect in the coldest weather that my Toyostove space heater may come on occationally also. Be happy you have Hitzer
The things almost run themselves.
