I had one installed 2 years ago, and I love it. I have a 2.5 story cape house in New England. The living room fireplace is on the ground floor (we have 8 foot ceilings, so the flue goes over 20 feet to the top) the flue has a slight bend in it, and the chimney is exposed on the north side of the house. When I tried to build a regular fire in the fireplace, it smoked terribly inside the house. The draft was awful. So I never used the fireplace. After 30 years, I decided to try a fireplace insert, after seeing a friend have success with them.
I basically am a complete novice, who has no idea what I'm doing with wood stoves. The local stove place is good, and they recommended the Lopi large insert with the cat, so I got that. Install was a bit of a pain in the ass because the installer gave me not enough info about the electrical conduit to run the fan. The cord runs down the ash dump, into the basement, then is tied into the electrical panel. I had to get an electrician to do this before they installed the stove, the stove place doesn't have an electrician, but the install people didn't give me any useful specs. So the electrician bolted the heat shield cable down, trying to do a good job, except the cable needs to be loose so they can attach it to the stove them slide it in. It sounds obvious after the fact, but I asked the stove place specifically for advice for the electrician, and they weren't clear enough on how to do it.
Another issue was my rectangular chimney flue had gobs of mortar on the inside of it, such that the regular sized metal stove pipe wouldn't fit down it. They had to use a slightly smaller metal stove pipe so it would fit down my flue, then add a cowl to where the pipe exits the stove. So the opening out the top of the stove is narrowed immediately to accommodate the smaller diameter pipe. Sorry if I'm not using the right terminology.
Anyway...After all that, the stove works awesome. I burn wood almost daily from Oct until April. I have an oil furnace, so the woodstove is just to supplement and for ambiance, not to be my main source of heating. But the stove heats well over 50% of the first floor, and of course the heat rises to the second floor.
I burn about 2-2.5 cord of wood a season. The fire starts super easy every time, zero issue with smoke coming out the stove. The draft is a million times better than it was with the conventional fireplace.
I had the chimney swept after the first season, and the guy said there was no issue with creosote, everything looked great.
So basically, I love this wood stove as an appliance that helps heat my house in cold weather, and it looks beautiful. I like to just stare at the fire. It works beautifully, the fire is warm and cozy every night, and it's very simple and easy to use. If you get a glass cleaner, and use it once every few weeks, the glass stays crystal clear.
If I had to give one negative, I would say that the blower fan is pretty loud. If you're sitting in the same room as the fire, you can't have it on high, because the noise will drive you nuts. It sounds almost as loud as a hair dryer. I run it like 50%. If you're not in the room, then you can crank it up all the way.
Any other questions, just let me know.
