Best Zero Clearance Wood Option

I am looking for a zero clearance wood solution for new construction shown below in red (it's about 55" between the window and sliding glass doors - obviously the chair shown wouldn't be there if we put a hearth in this spot). I have seen there are at least a few zero clearance inserts like the Lopi Hybrid Fyre and some Superior models. Ideally I'd want a Blaze King Sirocco 25 but those aren't zero clearance compatible AFAIK. This is a very well insulated home with a winter heating design of only 16000-18000 BTUs so we'd only likely want 11-18000 BTU fire burning in it. Any recommendations would be greatly appreciated. Thanks

Does anyone make any like the Rais Visio 3 available in the US:

So anything available or just questionable items like the Lennox CPF-38 (can't seem to find any data about BTUs, emissions, etc)

Saw the superior too but no specs on BTUs, emissions, etc.

The EU units seem to be high efficiency and have better doors on them. Why are the North American makers lazy?

Not sure now if we're doing a fireplace or going back to a woodstove now. The fireplace was considered because we could have a hearth and put a TV over it but we have concern the TV will be too high for comfortable use because you have to tilt your head too much. Even with a zero clearance model it looks like the bottom of the TV would be about 5' off the ground. Does anyone have a TV setup like that - will having a tilt TV wall mount make that less of a problem? We'll be sitting 6' from a 55" TV in the room.

Alternatively we'll put a wood stove or fireplace where we planned but put the TV in the NE corner of the room at normal height so it would 2.5-3' lower but the max TV we could fit in that corner is probably 49"?

I was wondering if anyone can offer feedback on this ZC fireplace - Supreme Astra24CF

Similar to the RSF Opel 3C, it's output is more like what we need in our super tight house but the style is better than the RSF and the fact it doesn't have a cat means we wouldn't have to worry about cat replacement in 5-7 years which can be a significant cost. It's also the most user friendly in log size - 24" logs is huge (vs 18" for RSF) and it burns for up to 10 hours which is nice. It also can use a variety of cheaper 6" chimneys rather than RSF that requires an expensive 7" Excel chimney.

Output is 12,237 to 23,872 BTU/hr which good.

Has an automatic air control feature that reminds me of the thermostat feature on the Blaze King:

Also if we did use the Astra24CF, which 6" chimney do you think is best? I'm not familiar enough to say which one is the best option and have only seen one or two brands in person - I think one was Duravent Plus HTC?

Is it worthwhile to get the more expensive 2" solid packs and which ones? Given that my home is well insulated the majority of the time I'll be burning smaller fires which I assume might create more creosote buildup which is why I was thinking the 2" might be a worthwhile investment (plus if I did end up putting a TV over the fireplace the extra insulation could help protect the TV from heated related problems?)

Any comment on Supreme or their Astra24?

I am thinking the Supreme Astra24CF with Excel 6" would be a great option. Wish I could get some feedback on the fireplace or Supreme in general.

Thanks again.

I looked more and found two options I liked better with lower minimum mantle heights too

Non-cat:
Superior WRT4820

Cat:
FireplaceX 42 Apex Clean Face Wood Fireplace
http://www.fireplacex.com/ProductGuide/ProductDetail.aspx?modelsku=98500107

Given that I will typical run low to med all the time - likely between 13000-18000 BTU/hr, which model do you think would better suit my application?
