Yes,no and maybe,lol! The Wega's were usually "Americanized" had a bit different control systems. Integras are considered heat monsters. They are quiet,but the room fan moves a lot of air. You will want to get the latest(the last one RIKA ever programmed) prom, as it has a "cleaning" feature, that you now see on other stoves.Once every hour or so, it speeds up combustion fan to max,and reduces pellet input,basically burns out/blows out the pot, it works very well. I used to heat my whole house/cabin with one from the basement.24' square,3 floors. But,getting older,and no need to heat basement that much,I have an Accentra in my living room,upstairs. Cut my pellet usage by almost 1/2, lol! But,I still have Integra, use it when it gets and stays below 0, nice to have warm floors, or if I need to do some work in basement. If you need a spare fire pot,pretty good sale right now. I dropped and broke my spare last year, will be getting one. When running full time,cold weather, I would start fire in spare pot, pull burning one out of stove(mostly out) empty ash pan, put in pan and spare,shut door, turn stove back on. Quick and easy. Stove never cools down.
