If you put several brands of stoves side by side you would see the visual differences.. the reading brand stoves are not cosmeticly very appealiing. I would say they often look a bit 'amateur' in construction... That is not to say bad,, just not a neat, orderly, square and appealing.
The triburner stoker unit is an old design.. it uses a single motor to run the stoker feed, and the combustion fan.. the new design stokers have an addtional combustion fan that runs full time,, this full time fan causes the coal to burn more completely and give you more heat from your coal.. The good news is that it is fairly easy to update the triburner design with an addtional fan that runs full time an creates the better burn in the stoker..
With the market on stoves that we have today,, if you can find a Reading stove that will work for your appication, just plan on adding an addtional combustion fan to the stoker.. and you will have a good unit... ANY coal burning stove is a good unit right now with the price of oil..
When Matthaus gets ot of the hospital I'll ask him to list the part numbers and maybe show a tutorial about how to modify the triburner stoker with the addtional fan..
When there were many stoves and brands to choose from,, I recommended to buy other brands than Reading.. I think the other brands are nicer and have more modern stokers and controls.. But now, with every manufacturer 5 months or more behind in filling new stove orders,, what ever you can find may be what you need to go with.
