We are - I attribute it primarily to the blower, also to adding insulation and milder temps (hasn't been under the teens at night here for a couple weeks, days in the high 40s). We'll really see how the blower works when we hit -20 plus 40mph sustained winds, but the forecast is disappointingly looking like more mild temps for the next week.
The 30 is serious heat at a cheap price; good quality and very simple to operate. Perfect for a huge room, a cabin, or an open house. But as a steel stove you really feel the heat next to it, and it's a hard stove to "just keep warm with" during milder temps. BrotherBart's setup with part of the stove in a fireplace is probably the best way, although side heat shields might help moderate it a bit. Think of it as a Ford Mustang - lots of power, gets the job done, and not a lot of frills.
By contrast, the T6 takes longer to warm up, and often doesn't give that hot woodstove feel next to it. The cast plates really do a good job moderating the intensity of the heat, which is what we wanted for the house layout we have. There are times when I still miss the blasting heat, but usually for about a minute after coming in from outdoors, and roasting all evening for a 2-minute "stove high" doesn't seem worth it... It also stays warmer longer, enough that it's noticeable when I get up in the AM. Overall, while it has taken us a bit to get used to the new stove, I think that the T6 does it's job well in an unassuming way, more like a Caddy - smoothly and before you know it you're cruising at 80.
All depends on what you want, the T6 is a beautiful stove and realistically the difference in price over 10+ years is negligible compared to saws, wood, reduced oil bill, comfort, and all the other economies of wood burning. We considered the Quad 5700, and the Jotul F600 as well; the quad 5700 seemed too much like an Englander with side shields for about 3X the cost, and the Jotul is a radiant stove, and way too much stove for our house (though I'll never repeat that blasphenous statement). The Mansfield was also in the running, but is a lot more $ (not a deciding factor for us, as mentioned) and the PE stoves seemed to have an excellent rep, be well built and simple to maintain (steel stove, with cast shell meant no cast firebox to worry about), and still offer a milder way of heating our home.
