You will find that all 2nd generation gasification stoves have a high degree of cleaning and maintenance that the older 1st generation stoves don't have. The newer stoves have 1000's of dollars of electronics that control all kinds of sensors and blowers. They all utilize expensive refractories that are usually proprietary to each manufacturer meaning expensive service cost's down the road.
Welcome to the forum. I take issue with BOTH of the statements made above. 1. I clean my boiler about every 5 weeks. It takes me about 30 minutes going slow and being anal. I don't consider that a 'high degree of cleaning' It's a wire boiler brush stuffed in a cordless drill.
As for refractory.. What are a couple nozzles for mine? ( I don't know.. I bought a cast iron replacement) I want to say that they were maybe 50 to 80 bucks for a nozzle. You'd likely have to do them every 3rd year ( I burn A LOT of wood for a single home) I don't consider less than 50 bucks a year amortized much money for a heating system that cost 10k to 15k. Heck.. with the money I'm saving I could HIRE out the few times a year cleaning, and likely not even spend as much as I did on oil boiler mtx.
