You guys also have to remember just because a stove can get long burn times doesn't mean it will heat a person's house burning that long. Yes the stove I am burning can burn 12 or even 24 hours but I rarely do that.
Worth repeating. You put half a million BTU's into a box, and then meter it out over a period of 4 - 24 hours. A
cat stove doesn't create more heat (other than a nearly-insignificant difference in efficiency), it only gives you more flexibility in the rate in which you meter out that load of ~500,000 BTU's. For some, this is an advantage, others may care less about that. Only you and your application will dictate whether that's important to you.
But, I also don't understand why you'd expect a cat stove to be more difficult for your wife to operate. My wife is definitely NOT into this whole wood stove thing, but does enjoy the heat they make. She loads them most weekends, if I'm up and out early, and has never had an issue with it. I've never run a modern non-cat, but to me the cat procedure sure sounds simpler:
1. Open bypass damper, and stick wood into stove, light if not a hot reload.
2. Let it get going, 5 - 15 minutes, then close bypass damper.
3. Run on high 15 - 30 minutes.
4. Turn down to final setting.
Someone who's run a non-cat can help you with the procedure on those, but I read too many threads here on this forum about people having trouble operating their non-cat's, to believe they're somehow much easier to operate. The
real down-sides of the cat stoves are:
1. You can't burn trash, pressure-treated wood, or anything else that might contaminate the catalyst. Only burn cord wood, un-treated lumber, or approved wood substitutes (eg. NEILS). The non-cats can burn treated wood, questionable pallet wood, and other things that we cannot without potentially reducing our catalyst lifespan or performance.
2. Having to replace the catalyst every few years. The oft-quoted number is 12,000 hours, amounting to about 3 years for most full-time burners, but there has always been debate about this with many running 2x - 3x longer with perhaps some accepted increase in emissions.
It also appears some new catalysts are giving much longer life, but perhaps the yearly cost is no different. Expect your catalyst to amortize around $50 - $65 per year, for most brands and models.
3. Possible clogged combustors. This has been an issue on a few stoves when run all day on high settings for maximum output, especially those with very tall chimneys. The issue is caused by fly ash stirred up when running on high, which can get sucked thru the combustor. If you're one with a very strong draft (tall chimney), the issue is resolved by either installing a key damper to bring your draft to within spec for your stove, not running on high all day, or settling for vacuuming your combustor once or twice mid-season.
If I were to buy a non-cat, the T5 would be at the top of my list. But I also don't think I'd ever buy a non-cat, as long as good cat stoves remain an option. Different strokes for different folks, we all have our own preferences.
